1 Changes in 0.6.2
2 - fix for using zsync client on files >2GB on 32bit systems.
3 - fix redirect handling.
4 - improve some edge cases dealing with unusual seed data patterns.
5 - optimise by stopping reading seed files if target file is complete.
6 - fix infinite loop in zsyncmake when given a truncated (invalid) .gz
7 - fix --disable-profile to configure.
8
9 Changes in 0.6.1
10 - recompression support for gzip files made with zlib:gzio.c or gzip -n
11 - fix compilation on MacOS X
12 - allow HTTP redirects on the target file; not sure whether this is a good idea
13 or not...
14 - fix unecessary transfer of whole file where file is smaller than the context
15 size (1x or 2x blocksize)
16 - use sequential_matches=1 when there is only one block; otherwise we're forced
17 to transfer the whole file for files below 2kiB
18 - fix librcksum handling of zsync streams with sequential_matches == 1; it was
19 giving false negatives when applying the rsync algorithm, resulting in poor
20 use of local source data when sequential_matches == 1 (which didn't actually
21 occur in any recent version of zsync)
22
23 Changes in 0.6
24 - fix out-of-bounds memory access when processing last block of non-compressed
25 download (patch from Timothy Lee). Also fix an error handling fault for the
26 same.
27 - fix "try a smaller blocksize" failures when zsyncmakeing for huge compressed
28 files on 32bit systems
29 - preserve mtime on downloaded files
30 - fix potential crash when re/deallocating checksum hash in librcksum (patch
31 from Timothy Lee)
32 - explain status code errors better
33 - better URL handling
34 - add -q as a substitute for -s, as -q is more conventional (re wget). -q also
35 suppresses the 'no relevant local data' warning now.
36 - fix some warnings
37 - code tidy-up and better commenting of what it is doing
38 - tidy up autoconf use
39
40 Changes in 0.5
41 - get large file support where possible
42 - replacement getaddrinfo on systems that lack it
43 - fix compilation on MacOS X
44
45 Changes in 0.4.3
46 - make -s suppress summary info too
47 - add HTTP authentication support
48
49 Changes in 0.4.2
50 - fix CAN-2005-1849 for embedded zlib
51 - obey -s flag
52
53 Changes in 0.4.1
54 - security fix from zlib-1.2.2
55 - generate RFC 1123 date strings in HTTP requests
56 - include port numbers in Host headers
57 - be slightly more accepting in proxy URL syntax
58 - don't generate Accept-Ranges headers
59
60 Changes in 0.4.0

62 - fixed incorrect 100%/done display of progress bar when cleanly disconnected before end by server
63 - updated autoconf/automake scripts
64
65 Changes in 0.3.3
66 - build in gzip in zsyncmake which produces .gz files optimised for zsync
67 - quickly stop downloading from a URL producing bad data
68 - -k option to keep the .zsync file, and redownload only when it changes
69 - fixes some possible crashes that could occur with unexpected remote responses
70
71 Changes in 0.3.2
72 - automatically decompress local seed data when this is appropriate
73 - progress bars with rate and ETA for all downloads
74 - automatically recompress downloaded file if possible
75 - deal better with local .zsyncs containing relative URLs
76
77 Changes in 0.3.1
78 - fix SEGV when downloading with no local data found
79 - fix failure when incomplete final block of uncompressed stream is unknown
80 - fix some memory leaks
81

93
94 Changes in 0.2.1
95 - fixed bug where zsync would loop if fed more than one local source file
96 - enabled zsync to handle gzip files containing stored (uncompressed) blocks (so we should do slightly better on gzipped binaries now - but this is still incomplete and will not work for all files)
97

100 - further fixes for servers refusing to do multipart/byteranges responses
