(3.0.2: performance fix)
------------------
3.0.1 - 2016-02-18
------------------
* Fix a case where it was possible to trigger an "Unreachable" assertion when
running certain flaky stateful tests.
* Improve shrinking of large stateful tests by eliminating a case where it was
hard to delete early steps.
* Improve efficiency of drawing binary(min_size=n, max_size=n) significantly by
provide a custom implementation for fixed size blocks that can bypass a lot
of machinery.
* Set default home directory based on the current working directory at the
point Hypothesis is imported, not whenever the function first happens to be
called.

3.0.0 - 2016-02-17
------------------
Codename: This really should have been 2.1.
Externally this looks like a very small release. It has one small breaking change
that probably doesn't affect anyone at all (some behaviour that never really worked
correctly is now outright forbidden) but necessitated a major version bump and one
visible new feature.
Internally this is a complete rewrite. Almost nothing other than the public API is
the same.
New features:
* Addition of data() strategy which allows you to draw arbitrary data interactively
within the test.
* New "exploded" database format which allows you to more easily check the example
database into a source repository while supporting merging.
* Better management of how examples are saved in the database.
* Health checks will now raise as errors when they fail. It was too easy to have
the warnings be swallowed entirely.
New limitations:
* choices and streaming strategies may no longer be used with find(). Neither may
data() (this is the change that necessitated a major version bump).
Feature removal:
* The ForkingTestCase executor has gone away. It may return in some more working
form at a later date.
Performance improvements:
* A new model which allows flatmap, composite strategies and stateful testing to
perform *much* better. They should also be more reliable.
* Filtering may in some circumstances have improved significantly. This will
help especially in cases where you have lots of values with individual filters
on them, such as lists(x.filter(...)).
* Modest performance improvements to the general test runner by avoiding expensive
operations
In general your tests should have got faster. If they've instead got significantly
slower, I'm interested in hearing about it.
Data distribution:
The data distribution should have changed significantly. This may uncover bugs the
previous version missed. It may also miss bugs the previous version could have
uncovered. Hypothesis is now producing less strongly correlated data than it used
to, but the correlations are extended over more of the structure.
Shrinking:
Shrinking quality should have improved. In particular Hypothesis can now perform
simultaneous shrinking of separate examples within a single test (previously it
was only able to do this for elements of a single collection). In some cases
performance will have improved, in some cases it will have got worse but generally
shouldn't have by much.
This is based on HTML files with a global YAML comment, currently with "target"
as the only allowed key.
The tests then do this:
- Open a HTML file in data/hints/html
- Start hinting
- Make sure only one hint is visible
- Follow it, and make sure the page mentioned in "target:" is reached
Some ideas for the future:
- A "scroll" key, to scroll before hinting
- A "zoom" key, to zoom
- Multiple hints via a list
- Checking position of hints?
- A mode to manually check the pages (to check hint positions)
- Fixed Jython compatibility
- Fixed HTML formatter output with leading empty lines
- Added a mapping table for LaTeX encodings and added utf8
- Fixed image formatter font searching on Macs
- Fixed deepcopy-ing of Token instances
- Fixed Julia string interpolation
- Fixed statefulness of HttpLexer between get_tokens calls
- Many smaller fixes to various lexers
Switched to a new changelog format (the one in http://keepachangelog.com/)
since it was contributed by Alexander Artemenko. Re-added a newline to support
old version of Python, as requested by azjps.
* Removed deprecated support for ``ssl_certificate`` and
``ssl_private_key`` attributes and implicit construction
of SSL adapter on Python 2 WSGI servers.
* Default SSL Adapter on Python 2 is the builtin SSL adapter,
matching Python 3 behavior.
* In proxy tool, defer to Host header for resolving the base if no base is
supplied.
- Fix file modes in archive
- Support forcing a platform tag using –plat-name on pure-Python wheels, as
well as nonstandard platform tags on non-pure wheels
- Add SOABI tags to platform-specific wheels built for Python 2.X
- Support reproducible wheel files, wheels that can be rebuilt and will hash to
the same values as previous builds
- Support for changes in keyring >= 8.0
- Use the file context manager when checking if dependency_links.txt is empty,
fixes problems building wheels under PyPy on Windows
- Don’t attempt to (recursively) create a build directory ending with ..
(invalid on all platforms, but code was only executed on Windows)
- Added the PyPA Code of Conduct
