3.44.20

This is a small refactoring release that changes how Hypothesis tracks some
information about the boundary of examples in its internal representation.

You are unlikely to see much difference in behaviour, but memory usage and
run time may both go down slightly during normal test execution, and when
failing Hypothesis might print its failing example slightly sooner.

3.44.19

This changes how we compute the default average_size for all collection
strategies. Previously setting a max_size without setting an
average_size would have the seemingly paradoxical effect of making data
generation slower, because it would raise the average size from its default.
Now setting max_size will either leave the default unchanged or lower it
from its default.

If you are currently experiencing this problem, this may make your tests
substantially faster. If you are not, this will likely have no effect on you.
