- Other minor fixes (756, 750, 749, 746)

0.3

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

Major release with several new features.

New Features
^^^^^^^^^^^^

- Revised timing benchmarking. ``asv`` will display and record the
median and interquartile ranges of timing measurement results. The
information is also used by ``asv compare`` and ``asv continuous``
in determining what changes are significant. The ``asv run`` command
has new options for collecting samples. Timing benchmarks have
new benchmarking parameters for controlling how timing works,
including  ``processes`` attribute for collect data by running
benchmarks in different sequential processes.
The defaults are adjusted to obtain faster benchmarking.
(707, 698, 695, 689, 683, 665, 652, 575, 503, 493)

- Interleaved benchmark running. Timing benchmarks can be run in
interleaved order via ``asv run --interleave-processes``, to obtain
better sampling over long-time background performance variations.
(697, 694, 647)

- Customization of build/install/uninstall commands. (699)

- Launching benchmarks via a fork server (on Unix-based systems).
Reduces the import time overheads in launching new
benchmarks. Default on Linux. (666, 709, 730)

- Benchmark versioning. Invalidate old benchmark results when
benchmarks change, via a benchmark ``version``
attribute. User-configurable, by default based on source
code. (509)

- Setting benchmark attributes on command line, via ``--attribute``.
(647)

- ``asv show`` command for displaying results on command line. (711)

- Support for Conda channels. (539)

- Provide ASV-specific environment variables to launched commands. (624)

- Show branch/tag names in addition to commit hashes. (705)

- Support for projects in repository subdirectories. (611)

- Way to run specific parametrized benchmarks. (593)

- Group benchmarks in the web benchmark grid (557)

- Make the web interface URL addresses more copypasteable.
(608, 605, 580)

- Allow customizing benchmark display names (484)

- Don't reinstall project if it is already installed (708)

API Changes
^^^^^^^^^^^

- The ``goal_time`` attribute in timing benchmarks is removed (and now
ignored). See documentation on how to tune timing benchmarks now.

- ``asv publish`` may ask you to run ``asv update`` once after upgrading,
to regenerate ``benchmarks.json`` if ``asv run`` was not yet run.

- If you are using ``asv`` plugins, check their compatibility.  The
internal APIs in ``asv`` are not guaranteed to be backward
compatible.

Bug Fixes
^^^^^^^^^

- Make ``asv compare`` accept named commits (704)
- Fix ``asv profile --python=same`` (702)
- Make ``asv compare`` behave correctly with multiple machines/envs (687)

- Perform benchmark discovery only when necessary (568)
- Fix benchmark skipping to operate on a per-environment basis (603)
- Allow putting ``asv.conf.json`` to benchmark suite directory (717)
- Miscellaneous minor fixes (735, 734, 733, 729, 728, 727, 726,
723, 721, 719, 718, 716, 715, 714, 713, 706, 701, 691, 688,
684, 682, 660, 634, 615, 600, 573, 556)

- Support for Windows. (282)
- New ``setup_cache`` method. (277)
- Exclude/include rules in configuration matrix. (329)

API Changes
^^^^^^^^^^^

- The parent directory of the benchmark suite is no longer inserted
into ``sys.path``. (307)
- Repository mirrors are no longer created for local repositories. (314)
- In asv.conf.json matrix, ``null`` previously meant (undocumented)
the latest version. Now it means that the package is to not be
installed. (329)
- Previously, the ``setup`` and ``teardown`` methods were run only once
even when the benchmark method was run multiple times, for example due
to ``repeat > 1`` being present in timing benchmarks. This is now
changed so that also they are run multiple times. (316)
- The default branch for Mercurial is now ``default``, not ``tip``. (394)
- Benchmark results are now by default ordered by commit, not by date. (429)
- When ``asv run`` and other commands are called without specifying
revisions, the default values are taken from the branches in
``asv.conf.json``. (430)
- The default value for ``--factor`` in ``asv continuous`` and
``asv compare`` was changed from 2.0 to 1.1 (469).
