Release 0.8.4
|

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

|
|
|
:Release: 0.8.4
|
|
:Date: TBD

Enhancements
|
|
~~~~~~~~~~~~
|
|
|
|
* Adds a way for users to specify context manager to use when executing the
|
|
scheduled functions (including ``handle_data``). This context manager will be
|
|
passed the :class:`~zipline.protocol.BarData` object for the bar and will
|
|
be used for the duration of all of the functions scheduled to run. This can be
|
|
passed to :class:`~zipline.algorithm.TradingAlgorithm` by the keyword argument
|
|
``create_event_context`` (:issue:`828`).
|
|
|

Experimental Features

Experimental features are subject to change.

|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
* Fixes an issue that would cause the daily/minutely method caching to change
|
|
the ``len`` of a :class:`~zipline.protocol.SIDData` object. This would cause
|
|
us to think that the object was not empty even when it was (:issue:`826`).
|
|
|
|
Performance
|
|
~~~~~~~~~~~
|
|
|
|
* Speeds up `AssetFinder.lookup_symbol` by adding an extension,
|
|
`AssetFinderCachedEquities`, that loads equities into dictionaries and
|
|
then directs `lookup_symbol` to these dictionaries to find matching equities
|
|
(:issue:`830`).
|
|
|
|
Maintenance and Refactorings
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
* Asset databases now contain version information to ensure compatibility
|
|
with current Zipline version (:issue:`815`).
|
|
|
|
Build
|
|
~~~~~
|
|
|
|
* Makes zipline install requirements more flexible (:issue:`825`).
|
|
* Use ``versioneer`` to manage the project ``__version__`` and setup.py version
|
|
(:issue:`829`).
|
|
* Fixed coveralls integration on travis build (:issue:`840`).
|
|
|
|
Documentation
|
|
~~~~~~~~~~~~~
|
|
|
|
* Document the release process for developers (:issue:`835`).
|
|
|
|
Miscellaneous
|
|
~~~~~~~~~~~~~
|
|
|
|
* Adds :func:`~zipline.utils.test_utils.subtest` decorator for creating subtests
|
|
without ``nose_parameterized.expand`` which bloats the test output
|
|
(:issue:`833`).
|
|
* Limits timer report in test output to 15 longest tests (:issue:`838`).
|
|
* Treasury and benchmark downloads will now wait up to an hour to download
|
|
again if data returned from a remote source does not extend to the date
|
|
expected. (:issue:`841`).
