   16 This is the XScreenSaver source code distribution.  It is strongly recommended
   17 that you install a binary release rather than trying to compile it yourself.
   18 Executables are available for almost all platforms, including macOS, iOS, and
   19 Android.  See the XScreenSaver web site for details.
   20 
   21 
   22 ===============================================================================
   23 To compile for a Unix system with X11:
   24 ===============================================================================
   25 
   26         ./configure --help
   27 
   28         ./configure --prefix=/usr
   29         make
   30         sudo make install
   31         make clean
   32 
   33         xscreensaver &
   34         xscreensaver-settings
   35 
   36     There are many compilation dependencies.  The configure script will
   37     tell you what is missing.  At the least, you will need development
   38     versions of these libraries:
   39 
   40         perl pkg-config gettext intltool libx11 libxext libxi libxt
   41         libxft libxinerama libxrandr libxxf86vm libgl libglu libgle
   42         libgtk2 gdk-pixbuf-2.0 gdk-pixbuf-xlib-2.0 libxml2 libpam
   43         dbus libsystemd elogind
   44 
   45     BSD systems might need gmake instead of make.
   46 
   47 
   48 ===============================================================================
   49 To compile for macOS or iOS:
   50 ===============================================================================
   51 
   52     See OSX/README.  Use the included Xcode project.
   53 
   54 
   55 ===============================================================================
   56 To compile for Android:
   57 ===============================================================================
   58 
   59     See android/README.

   82           and locking impossible.
   83 
   84 6.00	* X11: Major refactor of the `xscreensaver' daemon for improved
   85 	  security, dividing it into three programs: `xscreensaver',

  397 	* Kludged around the macOS pty bug that caused text to be truncated in
  398 	  phosphor, starwars, apple2, etc.
  399 	* New molecule in `molecule'.
  400 	* `glhanoi' now supports an arbitrary number of poles.

  403 
  404 5.11	* New versions of `photopile', `strange'.
  405 	* Worked around macOS 10.6 garbage collector bug that caused the
  406 	  screen saver process to become enormous.
  407 	* Fixed flicker in `pipes', `cubestorm', and `noof'.
  408 	* Fixed EXIF rotation on macOS 10.6.
  409 	* Fixed desktop-grabbing when screen locked on macOS.
  410 	* Minor fixes to `circuit', `polyhedra', `tangram', `gears', `pinion',
  411 	  `substrate', `xanalogtv'.
  412 	* Fixed some leaks in `xanalogtv' and `apple2'.
  413 	* Better seeding of the RNG.
  414 
  415 5.10	* Fixed some crashes and color problems on macOS 10.6.
  416 	* Retired `hypercube' and `hyperball', which are redundant with
  417 	  `polytopes'.
  418 
  419 
  420 5.09	* Ported to macOS 10.6, including various 64-bit fixes.
  421 	* New hack, `rubikblocks'.
  422 	* Fixed another potential RANDR crash.
  423 	* Use correct proxy server on macOS.
  424 	* `molecule' now correctly displays PDB 3.2 files.
  425 	* Updates to `mirrorblob', `glhanoi', and `sonar'.
  426 	* Rewritten version of `klein' hack.
  427 	* New hack, `surfaces', incorporating objects from old `klein' hack,
  428 	  plus new ones.
  429 	* Merged `juggle' and `juggler3d' hacks.
  430 	* Fixed compilation under gcc 4.4.0 (strict aliasing).
  431 	* Fixed intermittent failure in `xscreensaver-command'.
  432 
  433 5.08	* New hack, `photopile'.
  434 	* Rewrote `sonar' and `jigsaw' as OpenGL programs.
  435 	* Minor tweaks to `maze', `m6502', `hypnowheel', and `timetunnel'.
  436 	* Savers that load images now obey EXIF rotation tags.
  437 	* Arrgh, more RANDR noise!  Fixes this time for rotated screens, and
  438 	  for systems where RANDR lies and says the screen size is 0x0.
  439 	* When the password dialog has timed out or been cancelled, don't pop
  440 	  it right back up a second time.
  441 	* Password timeouts/cancels don't count as "failed logins".
  442 	* Retired some of the older, less interesting savers: say goodbye to
  443 	  `bubbles', `critical', `flag', `forest', `glforestfire', `lmorph',
  444 	  `laser', `lightning', `lisa', `lissie', `rotor', `sphere', `spiral',

  446 	* Merged `munch' and `mismunch'.
  447 	* Updated `webcollage' to use twitpic.com as well.
  448

  454 	* `blitspin' works with color images on macOS now.
  455 	* Added transparency to `stonerview'.
  456 	* Improved layout of the preferences dialogs: they should all now be

  458 	* macOS preferences text fields now prevent you from entering numbers
  459 	  that are out of range.
  460 	* Added "Reset to Defaults" button on X11.
  461 	* Added relevant Wikipedia links to many of the screen saver
  462 	  descriptions.
  463 	* All hacks support the `-fps' option, not just GL ones.
  464 	* The `-fps' option now shows CPU load.
  465 
  466 5.06	* Xinerama/RANDR fixes: this time for sure.  It should now work to
  467 	  add/remove monitors or resize screens at any time.
  468 	* New hack, `skytentacles'.
  469 	* New version of `gleidescope'.
  470 	* Added the `-log' option to the xscreensaver daemon, since a truly
  471 	  shocking number of Linux users seem to have no idea how to redirect
  472 	  output to a file.
  473 	* Added `-duration' arg to most image-loading hacks, so that they pick
  474 	  a new image every few minutes.
  475 	* Added an ATM crash to `bsod'.
  476 
  477 5.05	* New hacks, `cubicgrid', `hypnowheel', and `lcdscrub' (which isn't
  478 	  really a screen saver).
  479 	* Updates to `m6502' and `gears'.
  480 	* Fixed double-buffering problems in `cubestorm' and `noof'.
  481 	* Better handling of horizontal scroll wheels.
  482 	* Attempt to work around latest Xinerama braindamage: if the server
  483 	  reports overlapping screens, use the largest non-overlapping
  484 	  rectangles available.
  485 	* Don't warning about receipt of bogus ClientMessages, since Gnome's
  486 	  just never going to stop sending those.
  487 	* Worked around macOS 10.5 perl bug that caused the text-displaying
  488 	  hacks to fail on some systems.
  489 	* Hopefully fixed font-related System Preferences crashes in macOS
  490 	  savers.
  491 	* The recent PAM changes broke the "Caps Lock" warning in the password
  492 	  dialog, the failed login warnings, and syslogging.  Fixed all that.
  493 
  494 5.04	* Fixed a possible crash in the unlock dialog (more fallout from the
  495 	  recent PAM changes...)
  496 	* New hacks, `moebiusgears', `abstractile', and `lockward'.
  497 	* Rewrote `gears' to use better (involute) gear models, and to be more
  498 	  random.
  499 	* Minor updates to `cwaves', `voronoi', `deco', `glcells', `rd-bomb',
  500 	  `fireworkx' and `webcollage'.
  501 	* `pong' can now display the current time as the score.
  502 	* `xmatrix -mode pipe' works better.
  503 	* Minor tweaks for compilation on macOS 10.5.0.
  504 
  505 5.03	* New hacks, `cwaves', `glcells', `m6502', and `voronoi'.
  506 	* Minor fixes to `bsod'.
  507 	* Fixed possible crash with PAM USB-dongle auth.
  508 	* Updated `webcollage' to track recent Google Images and Flickr
  509 	  changes.
  510 
  511 5.02	* Reworked PAM code to support fingerprint readers, etc.
  512 	* Ported `webcollage' to macOS.
  513 	* Added macOS 10.2 and 10.3 kernel panics to `bsod'.
  514 	* Fixed a Xinerama crash when changing the screen count.
  515 	* New blobbier `mirrorblob'.
  516 	* Minor updates to `lisa', `bsod', `ifs', `hypertorus', `polytopes',
  517 	  `circuit', `endgame', `crackberg', `flipflop', `flipscreen3d',
  518 	  `fliptext', and `carousel'.
  519 	* Enabled multi-threaded OpenGL on macOS.
  520 
  521 5.01	* Backed out recent locale-related changes, since they broke far more
  522 	  things than they fixed.
  523 	* Fail gracefully with ridiculously small window sizes.
  524 	* `xflame' and `flag' ignore bitmap option on macOS.
  525 	* `speedmine' prefs work on macOS.
  526 	* Better explosions in `boxed'.
  527 	* More dynamic motion in `sproingies'.
  528 	* More options in `flipflop'.
  529 	* Minor updates to `topblock'.
  530 	* Various other minor fixes.
  531 
  532 5.00	* Ported to macOS! (10.4.0 or newer)
  533 	* API change: instead of providing a single screenhack() function that
  534 	  does not return, screen savers using the screenhack.h framework must
  535 	  now provide "init" and "draw one frame" functions instead.  All
  536 	  bundled savers have been updated; third-party patches will need
  537 	  work.
  538 	* All image-loading happens asynchronously.
  539 	* xscreensaver-getimage-file caches the contents of the image
  540 	  directory for a few hours, so consecutive runs won't have to re-list
  541 	  the whole directory tree.
  542 	* New hacks, `topblock' and `glschool'.
  543 	* Removed `xteevee' (superceded by `xanalogtv').
  544 	* Added variable-sized puzzle pieces to `jigsaw'.
  545 	* Changes to the defaults and command-line options of many hacks to
  546 	  make the .xml files more consistent.
  547 	* Reap zombies in `glslideshow' and `carousel'.
  548 	* `sonar' works without setuid on macOS (dgram icmp).
  549 	* `xmatrix -mode pipe' displays the text of a subprocess.
  550 	* `endgame' has higher resolution chess-piece models.
  551 	* `webcollage' takes a -directory option to get images from a local
  552 	  directory.
  553 	* The RPM spec file no longer auto-restarts xscreensaver when a new
  554 	  version is installed.  Restart it manually.
  555 
  556 4.24	* New versions of `cube21', `glsnake', `celtic'.
  557 	* Backed out a DPMS-related patch that cause desktop flickering with
  558 	  some X servers.
  559 	* Fixed startup crash in getgroups() when running setuid.
  560 	* Default to not displaying stderr on the saver window.
  561 	* Fixed bad free() in "Documentation" button.
  562 	* Don't try to run hacks that aren't installed.
  563 	* Minor fixes to various XML config files and man pages.
  564 
  565 4.23	* New hacks, `glhanoi', `cube21', `timetunnel', `juggler3d', and
  566 	  `celtic'.
  567 	* New versions of `tangram', `webcollage', `hypertorus', `polytopes',
  568 	  and `ripples'.
  569 	* `sonar' is now quiet about unresolvable hosts.
  570 	* Minor corrections to BASIC code in `apple2'.
  571 	* xscreensaver-demo now provides an RPM clue when none of the hacks
  572 	  seem to be installed.
  573 	* Don't install `ant' by default, since there is some Java tool of
  574 	  that name, which was causing confusion.  And also it's boring.
  575 	* Made screen grabbing work again on macOS 10.4.2.
  576 	* No longer prints bogus warnings about ClientMessages intended for
  577 	  the window manager.
  578 	* Ignore unprintable characters in passwd entry field.
  579 	* Fixed yet another cross-host-display image-loading endian problem.
  580 	* `xscreensaver-command -watch' and `-time' now work on 64-bit
  581 	  machines.
  582 
  583 4.22	* Fixed a bug in the new mouse-motion code that caused the screen to
  584 	  never blank on multi-head non-Xinerama systems.  Oops.
  585 	* New hacks, `interaggregate', `antmaze', `tangram', and `crackberg'.
  586 	* Minor tweaks to `fiberlamp', `ifs', `slidescreen', `zoom', `sonar',
  587 	  `fireworkx', `whirlwindwarp', `bubble3d', and `rd-bomb'.
  588 	* Added motion blur to `blinkbox'.
  589 	* `bsod' now includes Longhorn's "RSOD", and OS/2.
  590 	* Fixed `-wireframe' usage in most hacks and man pages.
  591 
  592 4.21	* New hack: `fliptext'.
  593 	* Changed default configure installation directories: /usr/bin/ for
  594 	  xscreensaver, etc.; /usr/libexec/xscreensaver/ for hacks;
  595 	  /usr/share/xscreensaver/config/ for xml files.
  596 	* All the text-manipulating screen savers can have their text source
  597 	  configured via `xscreensaver-demo' now.
  598 	* xscreensaver.spec now builds three RPMs: base (no hacks); extras (2d
  599 	  hacks); and gl-extras.
  600 	* Added `-program' and `-front' option to `gltext'.
  601 	* Added `-shells' to `molecule'.
  602 	* Fixed text-alpha glitch in `carousel'.
  603 	* New `pacman': the ghosts can be killed now.
  604 	* Fixed a bug in screen-grabbing GL hacks where images would be tiled
  605 	  instead of scaled on machines that can't do large textures.
  606 	* `webcollage' can hit Flickr now.
  607 	* New (rewritten) implementation of `ifs'.
  608 	* The unlock dialog can be made to have a "New Login" button that will
  609 	  run `gdmflexiserver'.  Experimental!
  610 	* Fixed non-ASCII display bug in `starwars'.
  611 	* Configure finds a default for imageDirectory.
  612 	* `xscreensaver-command -lock' now works even if in "screensaver
  613 	  disabled" mode.
  614 	* If a bad password is typed while CapsLock is on, the unlock dialog
  615 	  says "CapsLock?" instead of "Sorry".
  616 	* Mouse motion only counts as activity if the mouse moved more than 10
  617 	  pixels (so the screen won't unblank every time you bump your desk.)
  618 	* New mode option "random-same": if you have multiple monitors, this
  619 	  will run the *same* randomly chosen hack on each screen, instead of
  620 	  different ones on each.
  621 
  622 4.20	* New hacks, `fiberlamp', `boing', `boxfit', and `carousel'.
  623 	* Rewrote `glslideshow' again: should be faster now.
  624 	* Sped up loading of images in GL programs.
  625 	* `starwars' uses texture-mapped fonts now.
  626 	* New `bsod' modes: tru64, hppa, and nvidia.
  627 	* Updates to `webcollage', `juggle', `pinion', `fireworkx', `sonar',
  628 	  `extrusion', `substrate', and `pong'.
  629 
  630 4.19	* New hacks, `substrate', `intermomentary', `fireworkx', and `pinion'.
  631 	* New version of `flow'.
  632 	* Made /proc/interrupts work again on Linux 2.6.
  633 	* Made `analogtv' not hog the CPU.
  634 	* Made analogtv-based hacks work properly on PPC/ARM.
  635 	* Fixed a bad memory leak in `piecewise'.
  636 	* Minor updates to `sonar', `molecule', `glmatrix', `galaxy', and
  637 	  `webcollage'.
  638 	* Removed support for GTK 1.x (everyone uses 2.x now.)
  639 
  640 4.18	* Oops, pay no attention to the man behind the curtain.
  641 
  642 4.17	* New hacks, `anemotaxis' and `memscroller'.
  643 	* Fixed a bad bug that caused `vidwhacker' to never die.
  644 	* Fixed normals and lighting in `polyhedra'.
  645 	* Don't reuse the window when changing hacks (to work around bugs in
  646 	  some GL implementations.)
  647 	* Made `xscreensaver-getimage-file' skip thumbnail-sized images.
  648 	* Fixed endian problem in `barcode' on non-x86.
  649 	* Updates to `webcollage', `apple2', `fuzzyflakes', `atunnel', and
  650 	  `pacman'.
  651 	* Timing tweaks to `bubble3d', `bouncingcow', `engine', `gltext',
  652 	  `lavalite', `molecule', `spotlight', `sballs', `boxed', `blinkbox',
  653 	  and `circuit'.
  654 	* Configure updates for Fedora core 2 / xorg 6.7.0.
  655 	* Compile without warnings under gcc 3.3.3.
  656 	* I give up: don't blank or lock the screen if we can't get a keyboard
  657 	  grab.  In that case, both choices are bad.
  658 
  659 4.16	* New hacks, `polyhedra', `fuzzyflakes', `antinspect', and
  660 	  `providence'.
  661 	* Minor updates to `webcollage', `bsod', `endgame', `antspotlight',
  662 	  `xmatrix', and `glmatrix'.
  663 	* Added support for the RANDR (Resize and Rotate) extension to detect
  664 	  when the size of the desktop has been changed while xscreensaver is
  665 	  already running.
  666 	* Possibly-futile attempt to work around "rdesktop" focus/grab idiocy.
  667 	* Made `xscreensaver-getimage -file' still work even if imageDirectory
  668 	  is unset.
  669 	* Convert Latin1 to ASCII in `starwars' and `phosphor' (since the GLUT
  670 	  font only has ASCII glyphs.)
  671 	* Fixed randomization in `noof'.
  672 	* Added "GetViewPortIsFullOfLies" preference to work around
  673 	  longstanding XFree86 bug #421.
  674 	* Made `sonar' subnet pinging work properly on bigendian machines
  675 	  (e.g., PPC.)
  676 
  677 4.15	* New hacks, `wormhole', `mismunch', `noof', and `pacman'.
  678 	* `phosphor' and `apple2' include vt100 emulators now: this means you
  679 	  can do "phosphor -program top", or can use either program as an
  680 	  xterm replacement: "apple2 -text -fast -program 'xemacs -nw'".
  681 	* `analogtv' (and related) fill the screen better.
  682 	* The '-gradient' option works in `atlantis' now.
  683 	* Minor updates to `blinkbox', `queens', `endgame', `glmatrix',
  684 	  `mirrorblob', `blocktube', and `molecule'.
  685 	* Integrated SuSE's "external passwd helper" support.
  686 	* Marginally better /tmp handling in various programs.
  687 	* Updated config defaults for xplanet 1.0.3.
  688 	* Portability fixes.
  689 
  690 4.14	* New hacks, `fontglide', `apple2', `xanalogtv', `pong',
  691 	  `gleidescope', `mirrorblob', and `blinkbox'.
  692 	* New version of `glsnake' (with many more models.)
  693 	* Another Windows crash in `bsod'; also HVX/GCOS6/TPS6.
  694 	* New version of `endgame'.
  695 	* Screen grabbing works on macOS.
  696 	* Various minor fixes.
  697 
  698 4.13	* On Xinerama systems, xscreensaver now runs one hack on each monitor
  699 	  (just like in "real" multi-head mode) instead of running one hack
  700 	  stretching across all the screens.  Note that for this to work with
  701 	  any 3rd party screensavers, they must update their "vroot.h" file.
  702 	* `webcollage' and `vidwhacker' display images using
  703 	  `xscreensaver-getimage' now.
  704 	* Added `ljlatest' script for use with `starwars' and `phosphor'.
  705 
  706 4.12	* New GL hacks, `flipflop', `antspotlight', and `polytopes'.
  707 	* Added VMS to `bsod'.
  708 	* Compile without warnings in `gcc -pedantic'.
  709 	* Updates to `webcollage' and `queens'.
  710 	* Fixed a bug that could cause PAM to hang.
  711 
  712 4.11	* New hacks, `hypertorus', `cubestorm', `glknots', `blocktube', and
  713 	  `glmatrix'.
  714 	* Updates to `cloudlife', `engine', `xmatrix', and `sonar'.
  715 	* Rewrote `glslideshow': it should work on somewhat wimpier video
  716 	  cards now.
  717 	* Various portability tweaks.
  718 
  719 4.10	* New hacks, `cloudlife' and `klein'.
  720 	* Added Apple ][+, HPUX, and OS/390 sessions to `bsod'.
  721 	* Added some Matrix Reloaded text to `xmatrix'.
  722 	* Updates to `webcollage', `eruption', `jigglypuff', `metaballs', and
  723 	  `endgame'.
  724 	* Completely ignore the `memoryLimit' setting now, since it was still
  725 	  causing people GL grief.
  726 	* Various minor fixes.
  727 
  728 4.09	* New hacks, `flyingtoasters', `bouncingcow', `jigglypuff', and
  729 	  `glslideshow'.
  730 	* More models in `engine'.
  731 	* Rewrote `xscreensaver-getimage' to remove reliance on external image
  732 	  loaders (xv, chbg, xloadimage, etc.)  and to reduce flicker when
  733 	  loading files.
  734 	* Made `gflux' and `flipscreen3d' be mouse-spinnable.
  735 
  736 4.08	* New hacks, `atunnels' and `piecewise'.
  737 	* Physics improvement in `fluidballs'.
  738 	* Various fixes for XDarwin systems (X11 on macOS.)
  739 	* Added -clock option to `barcode'.
  740 	* Minor fixes to `endgame', `flurry', `flipscreen3d', and `gflux'.
  741 
  742 
  743 4.07	* New hacks, `flurry', `metaballs', `eruption', `popsquares', and
  744 	  `barcode'.
  745 	* Minor updates to `maze' for high density mazes.
  746 	* Added double buffering to `fluidballs' and `whirlygig'.
  747 	* Bug fixes for running xscreensaver to a remote XFree86 display
  748 	  (which nobody would ever do...)
  749 	* Updated `webcollage' (faster Alta Vista searching.)
  750 	* Updated `glplanet' so the sun sets in the west.
  751 	* Updated `sproingies' with smooth, unsegmented surfaces.
  752 	* Fixed Perl version-sensitivity in `xscreensaver-getimage-file'.
  753 	* Fixed GTK2 scrolling bug in `xscreensaver-demo'.
  754 
  755 4.06	* New hack, `glblur' (disabled by default, since it requires fast
  756 	  OpenGL texture support.)
  757 	* New hack, `halftone'.
  758 	* Updates to `endgame', `queens', `bumps', `glplanet', `engine', and
  759 	  `circuit'.
  760 	* New version of `menger' that uses far fewer polygons.
  761 	* Fixed minor bug in `critical' that could cause some bogus X servers
  762 	  to crash.
  763 	* Better labels in `molecule': the labels now appear to be attached to
  764 	  the atoms, instead of floating in front of the whole scene.
  765 	* Fixed bug that could rarely cause GL hacks to fail to double-buffer
  766 	  (causing intermittent flickering.)
  767 	* Fixed a relative-URL-parsing bug in `webcollage'.
  768 	* Fixed a bug that (sometimes) caused the window manager close box to
  769 	  kill `xscreensaver-demo' with a crash instead of a graceful exit.
  770 	* Updated xscreensaver.pam to the Red Hat 7.3 way.
  771 	* More Gnome2-related configure crap.
  772 	* Updated to latest `config.guess' and `config.sub'.
  773 	* Fixed occasional core dump in `distort'.
  774 	* Added a Linux fsck failure and kernel panic to `bsod'.
  775 	* Added macOS kernel panic to `bsod'.
  776 	* Fixed a bug in `bsod' (all bsod bugs are ironic.)
  777 	* Fixed a bug that caused `xscreensaver-gl-helper' to print a nonsense
  778 	  visual ID with some versions of `printf': this could cause GL
  779 	  programs to display incorrectly (e.g., flickery.)
  780 
  781 4.05	* More `configure' tweaks to try and get things working on systems
  782 	  that both Gtk 1.x and 2.x installed.
  783 	* New hack, `endgame'.
  784 	* Minor updates to `gltext'.
  785 
  786 4.04	* Support for GTK 2.x / GNOME 2.x.
  787 	* The `configure' script will now use `pkg-config' if you have it, in
  788 	  preference to `gtk-config', etc.
  789 	* New hacks, `lavalite', `queens', and `anemone'.
  790 	* Minor updates to `spheremonics', `gltext', `xmatrix'.
  791 	* You can use the mouse to manually spin most of the GL hacks now
  792 	  (when they are displaying in a window.)
  793 	* Fixed a bug in `webcollage' (due to recent Alta Vista url changes)
  794 	  that was causing it to try and load incorrect image URLs.
  795 	* Made `xscreensaver-getimage' use gdk_pixbuf if it is available: this
  796 	  means that those hacks that load images will no longer rely on `xv',
  797 	  `xloadimage', etc.  This will close a race condition that could
  798 	  sometimes cause your desktop background to be changed; and also
  799 	  makes it possible for those programs to operate on image files when
  800 	  running in windowed mode.
  801 	* `webcollage' can now be used in conjunction with `driftnet' to
  802 	  display images snooped from your local ethernet instead of obtained
  803 	  from search engines.
  804 	* Added man pages for all the hacks that didn't have them.
  805 
  806 4.03	* New hack, `spheremonics'.
  807 	* Minor updates to `webcollage', `cage', `moebius', `morph3d',
  808 	  `boxed', `circuit', and `helix'.
  809 	* `pulsar' and `extrusion' can now load texture JPEGs.
  810 	* `rubik' now does non-square cubes.
  811 	* `fluidballs' now does various sizes of balls.
  812 	* `menger' and `sierpinski3d' now also show polygon counts in -fps
  813 	  mode.
  814 	* `molecule' displays real subscripts in the formulae.
  815 	* GTK internationalization/localization support.
  816 	* Better detection of the various versions of libxml.
  817 	* Upgraded to autoconf 2.53 (from 2.13.)
  818 
  819 4.02	* Plugged a few minor leaks in `xscreensaver' and `xscreensaver-demo'.
  820 	* New hacks, `cubenetic' and `fluidballs'.
  821 	* Sped up `pipes'.
  822 	* Fixed sphere projection error in `glplanet'; installed a better
  823 	  image of earth.
  824 	* Added Win2K and MacOS 1 crashes to `bsod'.
  825 	* Put back previous (better) version of `forest' that was
  826 	  accidentially downgraded in the last release.
  827 	* New version of `bumps'.
  828 	* Made FPS computation in GL hacks more efficient: it will influence
  829 	  the results less, thus resulting in higher (but more accurate)
  830 	  reported frame rates.
  831 
  832 4.01	* New hacks: `twang', `glsnake', `boxed', `sballs', and
  833 	  `glforestfire'.
  834 	* New hacks `apollonian', `euler2d', `juggle', `polyominoes' and
  835 	  `thornbird', from xlockmore.
  836 	* Merged recent xlockmore changes into `ant', `braid', `demon',
  837 	  `discrete', `drift', `fadeplot', `forest', `grav', `hopalong',
  838 	  `ifs', `laser', `lightning', `lisa', `lissie', `loop', `mountain',
  839 	  `penrose', `rotor', `sierpinski', `slip', `sphere', `spiral',
  840 	  `strange', and `vines'.
  841 	* Fixed the `gltext' bug that sometimes caused horizontal lines to
  842 	  vanish again.  This time for sure.
  843 	* Sped up `webcollage' by adding a C helper program to replace the PPM
  844 	  pipeline.  It also pastes images semi-transparently now.
  845 	* Added support for the gdk_pixbuf library: if this lib is available,
  846 	  then `blitspin', `xflame', and `flag' can load GIF, JPEG, and PNG
  847 	  images in addition to XPM and XBM.
  848 	* Fixed a rare race condition where the desktop-grabbing hacks could
  849 	  sometimes leave the screen wedged, if the user moved the mouse
  850 	  exactly when they were grabbing the screen image (it would un-wedge
  851 	  the next time the saver timed out or was activated.)
  852 	* Fixed incorrect colors in the screen-grabbing GL hacks (`gflux' and
  853 	  `flipscreen3d'.)
  854 	* Made SIGHUP restart the daemon process (though using
  855 	  `xscreensaver-command -restart' is still the preferred way.)
  856 	* Tweaks to `xspirograph'.
  857 	* Minor configure and portability tweaks.
  858 
  859 4.00	* Redesigned `xscreensaver-demo' GUI: it now includes small-preview
  860 	  and per-hack configuration dialogs.
  861 	* Added three new modes of operation: `One Screen Saver', `Blank
  862 	  Screen', and `Don't Blank' (in addition to the historical `Random
  863 	  Screen Saver').
  864 	* Configure now defaults to installing the hacks in
  865 	  <prefix>/lib/xscreensaver/ instead of <prefix>/bin/.  (Most distros
  866 	  already did it this way.)
  867 	* New GL hacks, `menger', `engine', `flipscreen3d'.
  868 	* Made `sierpinski3d' be more colorful.
  869 	* New versions of `xmatrix' and `nerverot'.
  870 	* Fixed a bug in `starwars' that made the font be drawn with thin
  871 	  lines in -root mode.
  872 	* Fixed a bad colormap bug in `crystal' that could make *subsequent*
  873 	  hacks malfunction!
  874 	* Made `gflux' able to grab screen images (`-mode grab').
  875 	* Updated `webcollage' for recent search engine changes.
  876 	* Removed most command-line options to `xscreensaver': just edit the
  877 	  ~/.xscreensaver file instead.
  878 	* Improved behavior on multi-screen and Xinerama systems: the mouse
  879 	  now stays on the screen where the user left it, and the password and
  880 	  splash dialogs always appear on the screen that has the mouse.
  881 	* Made the splash dialog use more Gtk-like colors; made it have only
  882 	  two buttons, "Settings" and "Help".
  883 	* Made `sonar' understand `.ssh/known_hosts2' format files, and be
  884 	  better about stripping out illegal addresses.
  885 
  886 3.34	* Turned `memoryLimit' off by default, sigh.  Apparently some versions
  887 	  of the GL libraries (appear to) allocate hundreds of megs for every
  888 	  GL program, so `memoryLimit' was causing GL programs to malfunction
  889 	  or crash on those systems.
  890 	* Improved fading on TrueColor XFree86 4.1.x systems.
  891 	* New GL hack, `circuit'.
  892 	* Added `fuzz' mode to `decayscreen'.
  893 	* New version of `whirlygig'.
  894 	* Added links to `xplanet' and `sphereEversion'.
  895 	* Fixed rare race condition that could make `sonar' hang.
  896 	* Fixed potential crash in `speedmine'.
  897 	* Made `xscreensaver-demo' not crash when imageDirectory was set to a
  898 	  non-existent directory.
  899 	* Made `xscreensaver-getimage-video' invoke XawTV's `streamer' program
  900 	  better.
  901 	* Made `phosphor' and `starwars' deal with CR, LF, or CRLF line
  902 	  endings.
  903 	* Changes for Cygwin compilation environments.
  904 	* Made `sonar' compile on systems that can't ping.
  905 	* Configure changes for HPUX 10.20.
  906 	* Made PAM code work on Red Had 4.2 systems.
  907 	* Made `xscreensaver-command -deactivate' work when the saver is not
  908 	  active: what that does is reset the idle timer, as if keyboard input
  909 	  had been detected.  This was added for the benefit of people writing
  910 	  DVD-playing software: they can now prevent the screensaver from
  911 	  kicking in by sending a -deactivate message once a minute while the
  912 	  movie is playing and not paused.
  913 	* Various minor portability tweaks.
  914 
  915 3.33	* New hacks, `speedmine' and `whirlygig'.
  916 	* Sped up `pyro', made the explosions look a bit better.
  917 	* Added better stars to `glplanet' and `starwars'.
  918 	* Many internal changes to `webcollage'.
  919 	* Some new options to `attraction'.
  920 	* Minor fix to `noseguy' to avoid un-erased pixels.
  921 	* Rewrote the screen-eraser effects so that they complete in the same
  922 	  amount of time regardless of how slow your X server is (some of them
  923 	  were glacial on servers with slow blitting.)
  924 	* Fixed a potential free memory reference that could sometimes cause a
  925 	  crash at startup.
  926 	* Possibly fixed a problem that could cause the daemon to crash with
  927 	  an X error.  I was never able to reproduce this problem, but I think
  928 	  I might have figured out what caused it.
  929 	* Worked around a problem that caused PAM authentication to fail on
  930 	  some Red Hat 7.x systems.
  931 	* Added a `memoryLimit' parameter that controls the amount of memory a
  932 	  graphics hack may allocate: if they try to allocate more than this,
  933 	  malloc() will fail (and they will exit or (safely) crash, rather
  934 	  than hogging memory.)  Default is 50M.
  935 	* Made `gnome-help-browser' be the default way to display man pages in
  936 	  `xscreensaver-demo', if running on a GNOME system.
  937 
  938 3.32	* The image-manipulating hacks (`slidescreen', etc.) can now operate
  939 	  on randomly chosen image files from disk, or on frames captured from
  940 	  the system's video input, instead of (or in addition to)
  941 	  manipulating images of the desktop.
  942 	* Rewrote `vidwhacker' to use the new image-grabbing mechanism.
  943 	* Made fading work on TrueColor XFree86 4.x systems.
  944 	* Fixed a subtle rendering bug in `atlantis' (the fish were inside
  945 	  out!)
  946 	* Made `atlantis' have a texture simulating light reflections from the
  947 	  surface of the ocean.
  948 	* Fixed up label placement in `molecule'.
  949 	* Better color bars in `xteevee'.
  950 	* Made `install-strip' not try to strip scripts.
  951 
  952 3.31	* Put in more sensible defaults for DPMS, and updated the
  953 	  documentation to reflect the fact that all your DPMS settings are
  954 	  now belong to xscreensaver.
  955 	* Fixed the `xscreensaver.spec' file so that `--force' is no longer
  956 	  needed.
  957 	* New versions of `rotzoomer' and `nerverot'.
  958 	* Fixed an OSF/1 compilation problem in `molecule'.
  959 
  960 3.30	* New hacks, `molecule', `dangerball', and `rotzoomer'.
  961 	* New version of `gflux'.
  962 	* Made `gltext' able to display the current time.
  963 	* Fixed a floating-point-precision problem in `gltext' that sometimes
  964 	  caused horizontal lines to vanish.
  965 	* Removed the `-window-id' option from the hacks: it never worked
  966 	  right, and was unnecessary.
  967 	* Made the `starwars' hack use thicker lines, antialias the text, and
  968 	  fade out at the far edge instead of just dropping off.
  969 	* Fixed an SHM segment leak in `moire'.
  970 
  971 3.29	* Better rendering of the new logo.
  972 	* New hack, `gltext'.
  973 	* Added `-planetary' option to `gears', to draw a different kind of
  974 	  gear system.
  975 	* Made motion and rotation be smoother in `gears', `glplanet',
  976 	  `moebius', `rubik', and `sierpinski3d'.
  977 	* Improved coloration in `sierpinski3d'.
  978 	* Made the GL hacks react to window size changes.
  979 	* Made most of the GL hacks take a -fps option (like `pulsar' did), so
  980 	  you can use them to benchmark your 3D hardware.
  981 	* Fixed the previous fix to `sonar'.
  982 	* Minor fix to `nerverot'.  Made sonar able to ping hosts on DEC OSF1.
  983 	* Eliminated a bogus "didn't get enough colors" warning in some of the
  984 	  hacks.
  985 
  986 3.28	* New logo for xscreensaver!
  987 	* New hacks, `starwars' and `stonerview'.
  988 	* Made the motion of the bouncing ball in `stairs' be a little less
  989 	  jerky.
  990 	* Made newly-added screenhacks be added to .xscreensaver
  991 	  automatically: if there are hacks in the app-defaults file that are
  992 	  not also in ~/.xscreensaver, they will be added to the end of the
  993 	  list.
  994 	* Redid the `Screensaver Options' part of the control panel;
  995 	  xscreensaver now lets you configure your DPMS settings.
  996 	* Fixed some Makefile problems with non-GL builds.
  997 	* Fixed detection of MesaGL for version 3.3.
  998 	* Better workaround to Red Hat 7.0's broken gcc.
  999 	* Added Sparc Solaris kernel panic to `bsod'.
 1000 
 1001 3.27	* New hacks: `zoom' and `whirlwindwarp'.
 1002 	* Fixed a free-memory-reference bug in `sonar'.
 1003 	* Better error handling when there are no suitable GL visuals.
 1004 	* Added diagnostic dialog when xscreensaver-demo is unable to launch
 1005 	  xscreensaver (e.g., when running as root.)
 1006 	* Fixed a bug that caused screenhack argument changes to be ignored
 1007 	  when xscreensaver-demo was running as root (if "root" and "nobody"
 1008 	  have different home directories.)
 1009 	* Made the programs default to ":0" if $DISPLAY is unset.
 1010 	* Made the `-verbose' output include information about which server
 1011 	  extensions were supported at compile time.
 1012 	* Worked around Red Hat 7.0's broken gcc 2.96.
 1013 	* Updated default delays on the GL hacks to look better on machines
 1014 	  with super-fast 3D hardware.
 1015 	* Install `screensaver-properties-capplet' to work around the usual
 1016 	  egregious GNOME lossage.
 1017 
 1018 3.26	* Added "enabled" checkboxes in the list of hacks in xscreensaver-demo
 1019 	  (Gtk version only.)
 1020 	* New hacks `hyperball', `xrayswarm', and `gflux'.
 1021 	* New versions of `nerverot', `galaxy', and `hypercube'.
 1022 	* Small fixes to `phosphor', `shadebobs', `xflame', and `sonar'.
 1023 	* Added external helper program `xscreensaver-gl-helper' to figure out
 1024 	  which X visual to use for OpenGL programs.
 1025 	* Configure updates for XFree86 4.0, and for BSD.
 1026 	* Made it be more tolerant of bogus /etc/group files.
 1027 	* When installing the PAM config file, first try to just copy an
 1028 	  existing "xdm" or "login" config file, so that xscreensaver does
 1029 	  authentication in the same way as the rest of the system.
 1030 
 1031 3.25	* New hack, `nerverot'.
 1032 	* Added BSD kernel panic to `bsod'.
 1033 	* New version of `shadebobs'.
 1034 	* New version of `petri'.
 1035 	* Updated `webcollage' to handle recent Altavista URL format changes;
 1036 	  made it search the AP photo gallery.
 1037 	* Revamped command-line options of `sonar' and made it properly handle
 1038 	  subnets.
 1039 	* The `bubbles' hack can now trickle up or down the screen.
 1040 	* The `xsublim' hack can now read its text from programs.
 1041 	* Support for GLE version 3 in `extrusion'.
 1042 	* Fixed compilation problems in `maze'.
 1043 	* Fixed a rare crash in `flow'.
 1044 	* Fixes for minor installation problems.
 1045 
 1046 3.24	* Added `-ignorant' option to `maze' hack.
 1047 	* Updates to `critical', `bsod', `xflame', and `flow'.
 1048 	* Added support for Kerberos 5 (via its Kerberos 4 compatibility
 1049 	  layer.)
 1050 	* Fixed a bad leak in `xteevee'.
 1051 	* Updated `webcollage' to handle recent Altavista URL format changes.
 1052 	* Removed xscreensaver-demo's `Ok' and `Cancel' buttons, since they
 1053 	  were confusing people: all changes are now instantanious.
 1054 	* Made xscreensaver-demo install itself into the Gnome Control Center.
 1055 
 1056 3.23	* Fixed some misplaced text fields in the Motif version of
 1057 	  xscreensaver-demo; fixed a crash in the Gtk version that would
 1058 	  happen if the programs list was empty.
 1059 	* Fixed a recently-introduced bug in `pulsar'.
 1060 	* Made `sierpinski3d' use solid tetrahedrons instead of points.
 1061 	* Added `-trace' option to `xmatrix'.
 1062 	* Added new hacks `xteevee' and `xspirograph'.
 1063 
 1064 3.22	* Fixed some bugs in xscreensaver-demo.
 1065 	* Rewrote the Motif version of xscreensaver-demo to match the new Gtk
 1066 	  version.
 1067 	* The Athena toolkit is no longer supported.
 1068 
 1069 3.21	* Tweaked the xscreensaver-demo UI (Gtk only.)
 1070 	* Fixed a few visual selection bugs.  I think the proper GL visual
 1071 	  should be used with nVidia systems now.
 1072 	* Made the Makefiles obey $install_prefix.
 1073 	* Made the `xscreensaver.spec' file able to generate both GL and
 1074 	  non-GL packages simultaneously.
 1075 
 1076 3.20	* Added new hacks `ripples' and `sierpinski3d'.
 1077 	* Made `xscreensaver-command -exit' be silent when no screen saver was
 1078 	  running (instead of complaining.)
 1079 	* Made `webcollage' and `vidwhacker' use `xloadimage' when available
 1080 	  (in addition to `xli' and `xv'.)
 1081 	* Improved memory usage in `petri' and gave it a hard cap on how much
 1082 	  memory it can allocate.
 1083 	* Added `-watch' option to `xscreensaver-command'.
 1084 	* Made `xscreensaver-demo' come up with the most-recently-run hack
 1085 	  selected by default.
 1086 	* Rewrote the Gtk version of `xscreensaver-demo'.  It's a lot easier
 1087 	  to use now.
 1088 	* Extended the format of the programs list in the .xscreensaver file,
 1089 	  for the benefit of the new capabilities of `xscreensaver-demo'.
 1090 	  NOTE: you might want to delete your ~/.xscreensaver file and allow
 1091 	  it to be re-created!  The old one should still work, but
 1092 	  xscreensaver-demo won't be as pretty.
 1093 
 1094 3.19	* Fixed gcc dependencies in `bumps' and `ccurve'.
 1095 	* New hack, `extrusion'.
 1096 	* Some of the web sites that `webcollage' was using as its sources
 1097 	  changed formats; tweaked it to understand the current layouts.
 1098 	* Added typeahead in the password dialog: if the screen is locked, and
 1099 	  you unlock it by typing a character, that key will be automatically
 1100 	  inserted in the password dialog (unless it is Return, Enter, Space,
 1101 	  or a non-printing key like Shift.)
 1102 	* Made `xmatrix' take a `-small' option, since some folks with tiny
 1103 	  screens prefer a smaller font.
 1104 
 1105 3.18	* New versions of `shadebobs', `lmorph', and `distort'.
 1106 	* Added `ccurve', `blaster', and `bumps' hacks.
 1107 	* Replaced `forest' hack with a rewritten version.
 1108 	* Worked around a Xinerama server bug.
 1109 	* Fixed a bug I introduced in 3.10 that caused some hacks to print out
 1110 	  superfluous warnings about not having gotten enough colors.
 1111 	* Made `sproingies' obey the `-delay' option.
 1112 	* Fixed a portability bug in `shadebobs'.
 1113 	* Made `webcollage' and `vidwhacker' use `xli' in preference to `xv',
 1114 	  if it is available.
 1115 	* Added a new source of images to `webcollage'.
 1116 	* If running under KDE, xscreensaver will add itself to KDE's list of
 1117 	  screensavers (via xscreensaver.kss.)
 1118 	* Improved detection of GL libraries.
 1119 	* Made the password dialog include the date and time.
 1120 
 1121 3.17	* New version of `webcollage' -- deals better with corrupted images,
 1122 	  and can use an http proxy.
 1123 	* New hack, `xsublim' (run it in the background, rather than adding it
 1124 	  to the programs list.)
 1125 	* The xscreensaver daemon was leaking a file descriptor each time you
 1126 	  edited your .xscreensaver file.  Fixed.
 1127 
 1128 3.16	* New version of `shadebobs'.
 1129 	* Improved image selection in `webcollage', and sped it up slightly.
 1130 	* Made configure find the right version of perl.
 1131 	* Rewrote the CGI part of `webcollage'.
 1132 	* `make clean' was deleting some things it shouldn't.
 1133 	* Fixed a typo in the default programs list.
 1134 
 1135 3.15	* Added `webcollage' and `shadebobs' hacks.
 1136 	* Added a `-stdout' arg to `vidwhacker' so that it can be used in a
 1137 	  pipeline.
 1138 	* Made `petri' use less memory.
 1139 
 1140 3.14	* Various improvements to the Gtk port.
 1141 	* Turned off PAM by default on Solaris, since PAM seems generally to
 1142 	  be misconfigured out-of-the-box.
 1143 	* Made the `--without-gtk' configure option work.
 1144 	* Made configure check the Gtk version number, since it requires 1.2.
 1145 	* Fixed a bug in the code that attempted to prevent changes of screen
 1146 	  resolution while the screen is locked.
 1147 	* Fixed a race condition in `xscreensaver-demo' that could cause an X
 1148 	  error at startup.
 1149 	* Added `-transparent' option to `deluxe'.
 1150 	* Added `petri' hack.
 1151 
 1152 3.13	* Ported `xscreensaver-demo' to Gtk.
 1153 	* Made it possible to build Motif, Gtk, and Athena versions of
 1154 	  `xscreensaver-demo' in the same directory without reconfiguring.
 1155 	* Made `xscreensaver-demo' chase symlinks before writing the
 1156 	  .xscreensaver file, so that if .xscreensaver is itself a symlink,
 1157 	  the underlying file will be replaced instead.
 1158 	* Some Makefile and configure tweaks for Solaris and FreeBSD.
 1159 	* Made it possible to set the fire color in `xflame'.
 1160 	* Made transparency work in TrueColor (for `goop' and `qix'.)
 1161 	* Fixed a multi-head bug introduced by the virtual viewports stuff.
 1162 
 1163 
 1164 3.12	* Made it so that you can't scroll the screen while the lock dialog is
 1165 	  up (with XFree86 virtual viewports.)
 1166 	* Fixed a bug in `flag' that caused bob's chin to get cut off after a
 1167 	  few iterations.
 1168 
 1169 3.11	* Made `xjack' be black-on-white-ish, so that it looks less like a
 1170 	  computer screen and more like the typewritten paper it's supposed to
 1171 	  be.
 1172 	* New version of `pulsar'.
 1173 	* Fixed Solaris compilation problem in `phosphor'.
 1174 	* Made xscreensaver notice XFree86's virtual root window hack, so that
 1175 	  if the X server's root window is larger than the monitor's
 1176 	  displayable resolution, the screen saver will limit itself to the
 1177 	  area that actually appears on the screen.
 1178 	* Made the xscreensaver daemon do a better job of picking the visual
 1179 	  class that should be used for GL programs.  Less user intervention
 1180 	  should be needed now: you can use the logical visual name `GL'
 1181 	  instead of having to figure out by hand which one to use.
 1182 	* Oops, the visual was defaulting to "best" instead of
 1183 	  "default", because the .xscreensaver file was not being
 1184 	  loaded quite early enough.
 1185 	* Made configure figure out how to build icmp ping support into the
 1186 	  `sonar' hack automatically.
 1187 	* Made warnings about not being able to read shadow passwords not be
 1188 	  printed if compiled with PAM support.
 1189 	* Improved PAM startup diagnostics.
 1190 	* Worked around the Solaris PAM bug that was causing crashes there, so
 1191 	  now PAM is turned on by default.
 1192 	* Made configure detect the number of arguments that pam_strerror()
 1193 	  takes, since on Linux, this apparently changed between 2.0 and 2.2,
 1194 	  sigh.
 1195 	* Made the /proc/interrupts kludge look for "PS/2 Mouse" as well as
 1196 	  "keyboard".
 1197 	* Made xscreensaver notice when there has been a sudden large jump in
 1198 	  wall-clock time, and if so, lock right away, instead of waiting for
 1199 	  "lockTimeout" to expire first.  (Laptops need this for safer
 1200 	  recovery from hibernation.)
 1201 	* Added `-throttle' option to `xscreensaver-command'.
 1202 
 1203 3.10	* Added `phosphor', `xmatrix', and `pulsar' hacks.
 1204 	* Fixed a bug in the color allocator that sometimes caused `starfish'
 1205 	  to fall back to monochrome.
 1206 	* Reduced the amount of code that runs before root privileges are
 1207 	  disavowed: "normal" and "shadow" passwords now do some
 1208 	  initialization as root, but the PAM and Kerberos authorization
 1209 	  schemes will be initialized while running as "nobody".  Supposedly
 1210 	  this closes a potential security hole when using Kerberos.
 1211 	* Added some more sanity checking to configure.
 1212 
 1213 3.09	* Added `compass', `squiral', `xflame', `wander', `spotlight', and
 1214 	  `critical' hacks.
 1215 	* Added some new modes to `decayscreen'.
 1216 	* Made `deluxe' work in monochrome.
 1217 	* Generalized usage of the Double-Buffer server extension in several
 1218 	  hacks (`compass', `deluxe', `interference', `kumppa', and `moire2'.)
 1219 	* Fixed another visual-depth problem in `rd-bomb'.
 1220 	* The screen saver will now defer blanking if neither the keyboard nor
 1221 	  the mouse could be grabbed.  Instead, it will just try again in a
 1222 	  few minutes.  This fixes a bad interaction between xscreensaver and
 1223 	  programs like VMware that hold the mouse and keyboard grabbed for a
 1224 	  long time.
 1225 	* Added a new erase mode (expanding spiral.)
 1226 
 1227 3.08	* Fixed some bugs in my port of `t3d'.
 1228 	* Added `penetrate' and `deluxe' hacks.
 1229 	* When linking against Motif 2.x, also link against XPM.
 1230 	* Added support for using /proc/interrupts for idle detection on
 1231 	  Linux.  Now xscreensaver shouldn't kick in when the user is active
 1232 	  on a non-X virtual console.
 1233 	* Upgraded to autoconf 2.13.
 1234 
 1235 3.07	* Configure tweaks (sometimes -lXmu wasn't getting linked in properly;
 1236 	  check for _Xsetlocale in -lXintl.)
 1237 	* Portability fixes for sonar.c.
 1238 	* Fixed a compilation problem when you have GL but don't have XPM.
 1239 	* Made configure notice when MesaGL requires -lpthread.
 1240 	* Made `flame' ignore SIGFPE (not sure if this is the right fix; it
 1241 	  seems only to be needed on FreeBSD.)
 1242 	* Kludged `rd-bomb' work on visuals that are of depth 24 but that *do
 1243 	  not* support pixmaps of depth 32.
 1244 	* Fixed `halo' to work properly in TrueColor.
 1245 	* Changed `xscreensaver.spec' to install the hacks in
 1246 	  /usr/X11R6/lib/xscreensaver/ by default, since that's where recent
 1247 	  Red Hat distributions put them.
 1248 	* Added `t3d' hack.
 1249 	* Updated versions of `crystal', `hopalong', and `flow' from
 1250 	  xlockmore.
 1251 	* Imported `demon' and `loop' modes from xlockmore.
 1252 
 1253 3.06	* Oops, the "default-n" visual descriptor was broken; it was always
 1254 	  installing a colormap if the `installColormap' preference was set,
 1255 	  meaning that `xearth', `xv' and friends were using the wrong colors
 1256 	  on 8-bit systems.
 1257 	* Turned off HAVE_PING in `sonar', since it compiles on some Linux
 1258 	  systems, but not others of similar vintage...
 1259 
 1260 3.05	* Fixed an off-by-1 in `distort'.
 1261 	* Added `sonar' hack.
 1262 	* New version of `glplanet' (with stars.)
 1263 	* Made all hacks exit when you type `q' or `ESC' at them, and made
 1264 	  them obey the WM_DELETE_WINDOW ClientMessage.
 1265 	* Fixed a nonfatal buffer overrun in lament (note: lament still
 1266 	  doesn't work with MesaGL 3.0: it dies in
 1267 	  lambda_textured_triangle1(), which is Mesa's bug, not mine.)
 1268 
 1269 3.04	* Added an `xscreensaver.spec' file, to make it easier for other folks
 1270 	  to generate RPMs.
 1271 	* Made the password code work on HPUX in the situation where:
 1272 	  "enhanced security" is available; but not used; but the user typed
 1273 	  a password more than 8 characters long anyway.  FTSOHPUX.
 1274 
 1275 3.03	* Made locking work when passwd aging is enabled.
 1276 	* Added support for PAM (Pluggable Authentication Modules.)  It is
 1277 	  still turned off by default, though, since it doesn't seem to work
 1278 	  on Solaris 2.6, and has been behaving erratically on Red Hat 5.1.
 1279 	* Made each possible authentication method be tried in turn until one
 1280 	  succeeds; this means that Kerberos is being used, we will first
 1281 	  check Kerberos, and if that fails, will then consult the local
 1282 	  password file.  Likewise with PAM.
 1283 	* Save and restore the bits under the passwd dialog, to avoid leaving
 1284 	  a black rectangle behind when unlocking is cancelled.
 1285 
 1286 3.02	* Not everyone has sys/select.h, sigh...
 1287 
 1288 3.01	* Some fixes to `reflect'.
 1289 	* Configure tweaks.
 1290 	* Made it log unsuccessful attempts to unlock the screen to syslog.
 1291 	* Fixed a bug where `xscreensaver-demo' could be seeing a different
 1292 	  programs list than `xscreensaver' did.
 1293 
 1294 3.00	* The xscreensaver daemon no longer links against Motif or Athena:
 1295 	  demo-mode and the preferences panel are no longer built in to the
 1296 	  daemon, but are now handled by an external program,
 1297 	  `xscreensaver-demo'.  (I decided that this, along with the recent
 1298 	  addition of the `.xscreensaver' config file, justified bumping the
 1299 	  version number to 3.00, since this is a fairly major architectural
 1300 	  change.)
 1301 	* Lines in the `*programs' resource may now begin with the character
 1302 	  "-", meaning "don't run this hack."  In this way, it's possible to
 1303 	  disable a hack without throwing away the information about it
 1304 	  (making it easier to change your mind later.)  Eventually the
 1305 	  preferences/demo mode GUI should represent this as a checkbox or
 1306 	  something.
 1307 	* Fixed a short race condition where it was possible for xscreensaver
 1308 	  to die with a BadWindow error if it was blanking the screen just as
 1309 	  another window was being deleted.
 1310 	* Made it possible to disable specific modes in `bsod'.
 1311 
 1312 2.34	* Fixed a bug that was making `pipes' generate way too many valves.
 1313 	  Made the viewpoint in `pipes' be selected randomly instead of always
 1314 	  being -10 degrees.
 1315 	* Fixed a bug in the XSHM code, in the case where the server supports
 1316 	  the XSHM extension but is not the same machine as the client.
 1317 	* Made `rd-bomb' default to taking up the whole screen.
 1318 	* Made it not try to do fading/unfading if no PseudoColor visuals
 1319 	  exist.
 1320 	* Initial attempt at supporting VT-locking (doesn't work yet.)
 1321 	* Eliminated the `captureStdout' resource; now `captureStderr'
 1322 	  controls both streams.
 1323 	* Added `-capture-stderr' and `-no-capture-stderr' command-line
 1324 	  arguments.
 1325 	* Added `glplanet' hack.
 1326 	* When a hack is selected with `xscreensaver-command -select', that
 1327 	  hack will be used until further notice (until the saver turns off,
 1328 	  or another activation command is issued.)
 1329 
 1330 2.33	* Made `xscreensaver-command' print error messages: the xscreensaver
 1331 	  daemon now responds to ClientMessage events by writing a response
 1332 	  message on a window property, instead of just writing to its stderr.
 1333 	* Made the ~/.xscreensaver file be automatically reloaded when the
 1334 	  file date changes.
 1335 	* The password dialog and splash screen no longer depend on Motif or
 1336 	  Athena.  This should clear up a number of focus problems, and is the
 1337 	  first step on the path toward moving all of the
 1338 	  Motif/Athena/whatever code out of the xscreensaver daemon, and into
 1339 	  external processes.
 1340 	* Don't complain about LessTif 0.86 any more, since the new password
 1341 	  dialog makes that problem go away.
 1342 	* Configure tweaks for Irix 6.5, SunOS 5.something.
 1343 	* New `-reflect' option to `distort'.
 1344 
 1345 2.32	* Added reading and writing of a ~/.xscreensaver file, so that the
 1346 	  Preferences panel can save its settings.
 1347 	* New version of `rubik'.
 1348 	* Added `-select N' argument to `xscreensaver-command'.
 1349 	* Oops, left out some of the `bubbles3d' files...
 1350 
 1351 2.31	* The cursor was invisible in the password dialog. Fixed.
 1352 	* Made configure warn against MesaGL 2.6.
 1353 	* Fixed X error at startup when using non-default visual.
 1354 	* New version of `crystal', `ant', and `atlantis' from xlockmore.
 1355 	* New hack, `bubble3d'.
 1356 	* Added some new modes to `bsod'.
 1357 
 1358 2.30	* Changed the order in which -lSM and -lICE are linked to be after
 1359 	  Motif instead of before (Lesstif on Irix needs this.)
 1360 
 1361 2.29	* Work around a bash bug in configure.
 1362 	* Tweaked HPUX paths again.  FTSOHPUX.
 1363 	* Made configure recommend against LessTif 0.86, due to a bug in that
 1364 	  version that causes a security hole in the screen locking code.
 1365 	  LessTif 0.87 will fix it.
 1366 	* Made all of the `--with' options to `configure' accept a directory
 1367 	  option as well (so that --with-motif=/FOO will add -I/FOO/include
 1368 	  -L/FOO/lib).  I believe this is the Configure Party Line of how do
 1369 	  to such things.
 1370 	* Fixed a bug where the mouse was left un-grabbed after the first time
 1371 	  the graphics hack was changed (simplified all of the mouse-grabbing
 1372 	  logic.)
 1373 	* Maybe possibly perhaps made `vidwhacker' really not leave stray xv
 1374 	  windows around.  This time for sure.
 1375 	* Added a new erase mode (random dots fizzling out.)
 1376 	* Added `-prefs' argument to `xscreensaver-command', that brings up
 1377 	  the Preferences dialog directly (it seems that nobody ever noticed
 1378 	  the `Preferences' button on the Demo Mode dialog, maybe this will
 1379 	  help.)
 1380 	* Added a splash screen.  Turn it off with *splash:false.
 1381 
 1382 2.28	* Better macsbug text in `bsod'.
 1383 	* New version of `distort' with many new modes.
 1384 	* Plugged a leak in `coral'.
 1385 	* Tweaked configure for HPUX.
 1386 	* Removed some compiler warnings.
 1387 	* More consistent usage of stderr versus stdout.
 1388 	* More diagnostics should an X error occur.
 1389 	* Fixed a possible crash in SGI-specific unfading code.
 1390 
 1391 2.27	* Improved version of `distort'.
 1392 	* Made `lament' compile against OpenGL 1.0 (though it still requires
 1393 	  1.1 to work properly.)
 1394 	* Updated my email address and home page.
 1395 
 1396 2.25	* Improved motion in `rd-bomb'.
 1397 	* Added XSHM (shared memory extension) support to the `distort',
 1398 	  `interference', `moire', `rd-bomb', and `swirl' hacks, which speeds
 1399 	  them up a bit.
 1400 	* Added `lament' hack.
 1401 
 1402 2.24	* Tweaked the order of the -L options again.
 1403 	* Cleaned up configure's `--help' message.
 1404 	* Added `kumppa' hack.
 1405 	* Smarter maze-solving algorithm in `maze'.
 1406 	* Took `xlyap' out of the default list of hacks, since it's just
 1407 	  incredibly buggy (and slow.)  Maybe someday someone will fix it...
 1408 	* Added `distort' hack, but didn't add it to the default list (yet)
 1409 	  because it's still too slow.
 1410 	* Made the Athena demo dialog look more like the Motif version; it has
 1411 	  a text-entry field now, too.
 1412 	* Made the Athena password dialog echo asterisks, like Motif does,
 1413 	  instead of using a flyspeck font.
 1414 	* Some random configure tweaks.
 1415 	* Added a `timestamp' resource that makes the `-verbose' messages
 1416 	  include the time at which they were printed.
 1417 
 1418 2.23	* The fix for SGI's "scheme" nonsense broke things, and let the
 1419 	  user's "*background" resource show through.  Fixed it in a different
 1420 	  way.
 1421 
 1422 2.22	* Added support for the DPMS server extension (Display Power
 1423 	  Management System.)
 1424 	* Made configure advertize the `--enable-subdir' option a little more,
 1425 	  since that seemed to cause some people stress.  Also, made that
 1426 	  directory be built into the xscreensaver executable, as a hardcoded
 1427 	  prefix to $PATH.  (Might help, shouldn't hurt.)
 1428 	* Made configure prefer the two-arg gettimeofday to the one-arg
 1429 	  version, since AIX doesn't have any prototypes.
 1430 	* Made it work with Xaw3d (the 3D Athena library.)
 1431 	* Made `make install' create directories as necessary.
 1432 	* New version of lmorph from Sverre.
 1433 	* Added `crystal' and `discreet' hacks from xlockmore.
 1434 	* Added a new mode to `bsod'.
 1435 
 1436 2.21	* Made `xscreensaver-command -time' use different words.  (It now
 1437 	  describes the two states as "screen blanked since..."  and "screen
 1438 	  non-blanked since..." instead of "active since..." and "inactive
 1439 	  since..." which a lot of people interpreted as meaning the opposite
 1440 	  of what was intended.)
 1441 	* Improved some error messages, in the hopes of making the distinction
 1442 	  between the xscreensaver and xscreensaver-command programs more
 1443 	  obvious.
 1444 	* Rewrote (and reorganized) parts of the xscreensaver and
 1445 	  xscreensaver-command manual pages.
 1446 	* Renamed xscreensaver's `-lock' command-line option to be
 1447 	  `-lock-mode', to avoid confusion with the `-lock' option to
 1448 	  xscreensaver-command, which does a totally different thing.
 1449 	* Removed xscreensaver's `-demo' command-line option for a similar
 1450 	  reason; use `xscreensaver-command -demo' instead.
 1451 	* Disabled SGI's "scheme" nonsense in a better way than
 1452 	  fully-qualifying the background colors in every single hack.
 1453 	* Fixed some other minor cosmetic problems when *sgiMode is turned on.
 1454 	* Fixed an X error in `bsod -root' (how ironic...)
 1455 
 1456 2.20	* Fixed a bug that caused the mouse to sometimes not be grabbed
 1457 	  properly (meaning the window manager menu could pop up over the
 1458 	  demo-mode display.)
 1459 	* Fixed a bug that made the stderr output sometimes get printed twice.
 1460 	* Fixed a bug that made the demo-mode scrollbar move too fast.
 1461 	* Protected against a possible buffer overflow.
 1462 	* Made `vidwhacker' not leave stray xv windows around.
 1463 	* New version of `ant' so that Bagley doesn't calve.
 1464 	* Make configure on AIX get XShm from the right library.
 1465 
 1466 2.19	* One file was missing from the tar file.
 1467 
 1468 2.18	* Oops, atlantis wasn't being built by default.
 1469 	* Added `epicycle' hack.
 1470 	* Added `interference' hack.
 1471 	* Added `truchet' hack.
 1472 	* Added `bsod' hack.
 1473 	* Added some new modes to `vidwhacker'.
 1474 
 1475 2.17	* Added a -window-id argument to most hacks, so that they can draw on
 1476 	  arbitrary externally-provided windows.
 1477 	* Synched with xlockmore 4.11a01.
 1478 	* Added `flow' hack.
 1479 	* Added `atlantis' GL hack.
 1480 	* Renamed `puzzle' hack to `jigsaw', since xlock already had a
 1481 	  different mode called `puzzle'.
 1482 	* Made it self-configure properly when Motif 2.1.0 is being used
 1483 	  (requires -lXp now, sigh...)
 1484 
 1485 2.16	* Made `flag' able to do XPM images.
 1486 	* New look for the xscreensaver logo (`xroger').
 1487 	* Fixed compilation error on Suns with adjunct passwords.
 1488 	* Got multi-architecture builds working again.
 1489 	* Some configure tweaks for building on HPUX and Solaris.
 1490 	* Fixed bug in decayscreen.
 1491 	* Fixed typo in passwd.c.
 1492 	* Made `cynosure' not die when colormap is full.
 1493 
 1494 2.15	* Added `cynosure' hack.
 1495 	* Added `moire2' hack.
 1496 	* Tweaked `erase.c' some more.
 1497 	* Made unfading a bit smoother.
 1498 	* Added `vidwhacker' hack (not installed by default.)
 1499 	* Added `stairs' hack.
 1500 	* Split `escher' into `cage' and `moebius', as per xlockmore.
 1501 	* Changed subprocess handling to use sigaction() instead of signal()
 1502 	  if it's available (this is necessary for SCO but should work fine on
 1503 	  other systems too.)
 1504 	* Various other tweaks.
 1505 
 1506 2.14	* Better fix for the Motif drag-and-die lossage.
 1507 	* Put in some kludges to work around a LessTif bug.
 1508 	* XScreenSaver is known to work with LessTif 0.82 now.
 1509 	* Made fading work on high-end SGI video hardware.
 1510 	* Fixed another SGI-specific bug in screen grabbing; will the madness
 1511 	  never cease?
 1512 	* Fixed another crash in `xlyap'.
 1513 
 1514 2.13	* Made `decayscreen' do directions other than down.
 1515 	* Improved `puzzle'.
 1516 	* Fixed a crash in `xlyap'.
 1517 	* Added CDE info to the man page, removed `cde.txt'.
 1518 	* Configure tweaks for Zippy.
 1519 	* Turned off the signal handling in `bubbles' because it was sometimes
 1520 	  failing to die.
 1521 	* Added `hacks/xscreensaver-sgigl.c' to make it possible to run SGI's
 1522 	  ElectroPaint hack (/usr/demos/bin/ep) with xscreensaver.  Finally!
 1523 	* Fixed a buffer overrun in the locking code that some wily, malicious
 1524 	  cracker must have slipped in.
 1525 	* Disabled Motif drag-and-drool in the dialog box buttons, since it's
 1526 	  broken in some old versions of Motif.
 1527 
 1528 2.12	* Added `README.debugging'.
 1529 	* Added `puzzle' hack.
 1530 	* Added `xlyap' hack.
 1531 	* Added `default-n' as a visual name, so that one can have -install on
 1532 	  by default, but turn it off for certain poorly-behaved hacks (like
 1533 	  xv.)
 1534 	* Added support for grabbing frames of external video (on SGI) to the
 1535 	  screen-grabbing hacks (decayscreen, slidescreen, slip, blitspin, and
 1536 	  puzzle.)
 1537 	* Improved look of tiles in `slidescreen'; fixed its color allocation
 1538 	  problem.
 1539 
 1540 2.11	* Tweaked `blitspin', added it to the default list.
 1541 	* Added `lissie', `mountain', `triangle', `worm', `rotor', and `ant'
 1542 	  from xlockmore.
 1543 	* Updated `sierpinski', `galaxy', and `lisa'.
 1544 	* Thickened the lines in `braid' and `lmorph'.
 1545 	* Updated VMS makefiles.
 1546 	* Renamed `fract' to `vines'.
 1547 	* Added `xjack' hack.
 1548 	* Made a few more hacks use erase.c, and added a few more wipe styles.
