Hypothesis

------------------

Codename: T-1 days.

* floats_in_range would not actually have produced floats_in_range unless that
range happened to be (0, 1). Fix this.

------------------

Codename: T-2 days.

* Fix a bug where if you defined a strategy using map on a lambda then the results would not be saved in the database.
* Significant performance improvements when simplifying examples using lists, strings or bounded integer ranges.

------------------

Codename: The final countdown

This release could also be called 1.0-RC1.

It contains a teeny tiny bugfix, but the real point of this release is to declare
feature freeze. There will be zero functionality changes between 0.9.0 and 1.0 unless
something goes really really wrong. No new features will be added, no breaking API changes
will occur, etc. This is the final shakedown before I declare Hypothesis stable and ready
to use and throw a party to celebrate.

Bug bounty for any bugs found between now and 1.0: I will buy you a drink (alcoholic,
caffeinated, or otherwise) and shake your hand should we ever find ourselves in the
same city at the same time.

The one tiny bugfix:

* Under pypy, databases would fail to close correctly when garbage collected, leading to a memory leak and a confusing error message if you were repeatedly creating databases and not closing them. It is very unlikely you were doing this and the chances of you ever having noticed this bug are very low.

------------------

Codename: Hygienic macros or bust

* You can now name an argument to given 'f' and it won't break (:issue:`38`)
* strategy_test_suite is now named strategy_test_suite as the documentation claims and not in fact strategy_test_suitee
* Settings objects can now be used as a context manager to temporarily override the default values inside their context.

------------------

Codename: Point releases go faster

* Better string generation by parametrizing by a limited alphabet
* Faster string simplification - previously if simplifying a string with high range unicode characters it would try every unicode character smaller than that. This was pretty pointless. Now it stops after it's a short range (it can still reach smaller ones through recursive calls because of other simplifying operations).
* Faster list simplification by first trying a binary chop down the middle
* Simultaneous simplification of identical elements in a list. So if a bug only triggers when you have duplicates but you drew e.g. [-17, -17], this will now simplify to [0, 0].

-------------------

Codename: Starting to look suspiciously real

This is probably the last minor release prior to 1.0. It consists of stability
improvements, a few usability things designed to make Hypothesis easier to try
out, and filing off some final rough edges from the API.

* Significant speed and memory usage improvements
* Add an example() method to strategy objects to give an example of the sort of data that the strategy generates.
* Remove .descriptor attribute of strategies
* Rename descriptor_test_suite to strategy_test_suite
* Rename the few remaining uses of descriptor to specifier (descriptor already has a defined meaning in Python)
