    2 features:
    3   - Added a new config option ``scheduler_weight_handler``. This is a global
    4     option which specifies how the scheduler should choose from a listed of
    5     weighted pools. By default the existing weigher is used which always
    6     chooses the highest weight.
    7   - Added a new weight handler ``StochasticHostWeightHandler``. This weight
    8     handler chooses pools randomly, where the random probabilities are
    9     proportional to the weights, so higher weighted pools are chosen more
   10     frequently, but not all the time. This weight handler spreads new
   11     shares across available pools more fairly.
