pytest-xdist 2.5.0 (2021-12-10)
===============================

Features
--------

- `#722 <https://github.com/pytest-dev/pytest-xdist/issues/722>`_: Full compatibility with pytest 7 - no deprecation warnings or use of legacy features.

- `#733 <https://github.com/pytest-dev/pytest-xdist/issues/733>`_: New ``--dist=loadgroup`` option, which ensures all tests marked with ``@pytest.mark.xdist_group`` run in the same session/worker. Other tests run distributed as in ``--dist=load``.


Trivial Changes
---------------

- `#708 <https://github.com/pytest-dev/pytest-xdist/issues/708>`_: Use ``@pytest.hookspec`` decorator to declare hook options in ``newhooks.py`` to avoid warnings in ``pytest 7.0``.

- `#719 <https://github.com/pytest-dev/pytest-xdist/issues/719>`_: Use up-to-date ``setup.cfg``/``pyproject.toml`` packaging setup.

- `#720 <https://github.com/pytest-dev/pytest-xdist/issues/720>`_: Require pytest>=6.2.0.

- `#721 <https://github.com/pytest-dev/pytest-xdist/issues/721>`_: Started using type annotations and mypy checking internally. The types are incomplete and not published.


pytest-xdist 2.4.0 (2021-09-20)
===============================

Features
--------

- `#696 <https://github.com/pytest-dev/pytest-xdist/issues/696>`_: On Linux, the process title now changes to indicate the current worker state (running/idle).

  Depends on the `setproctitle <https://pypi.org/project/setproctitle/>`__ package, which can be installed with ``pip install pytest-xdist[setproctitle]``.

- `#704 <https://github.com/pytest-dev/pytest-xdist/issues/704>`_: Add support for Python 3.10.


pytest-xdist 2.3.0 (2021-06-16)
===============================

Deprecations and Removals
-------------------------

- `#654 <https://github.com/pytest-dev/pytest-xdist/issues/654>`_: Python 3.5 is no longer supported.


Features
--------

- `#646 <https://github.com/pytest-dev/pytest-xdist/issues/646>`_: Add ``--numprocesses=logical`` flag, which automatically uses the number of logical CPUs available, instead of physical CPUs with ``auto``.

  This is very useful for test suites which are not CPU-bound.

- `#650 <https://github.com/pytest-dev/pytest-xdist/issues/650>`_: Added new ``pytest_handlecrashitem`` hook to allow handling and rescheduling crashed items.


Bug Fixes
---------

- `#421 <https://github.com/pytest-dev/pytest-xdist/issues/421>`_: Copy the parent process sys.path into local workers, to work around execnet's python -c adding the current directory to sys.path.

- `#638 <https://github.com/pytest-dev/pytest-xdist/issues/638>`_: Fix issue caused by changing the branch name of the pytest repository.


Trivial Changes
---------------

- `#592 <https://github.com/pytest-dev/pytest-xdist/issues/592>`_: Replace master with controller where ever possible.

- `#643 <https://github.com/pytest-dev/pytest-xdist/issues/643>`_: Use 'main' to refer to pytest default branch in tox env names.


pytest-xdist 2.2.1 (2021-02-09)
===============================

Bug Fixes
---------

- `#623 <https://github.com/pytest-dev/pytest-xdist/issues/623>`_: Gracefully handle the pending deprecation of Node.fspath by using config.rootpath for topdir.


pytest-xdist 2.2.0 (2020-12-14)
===============================

Features
--------

- `#608 <https://github.com/pytest-dev/pytest-xdist/issues/608>`_: Internal errors in workers are now propagated to the master node.


pytest-xdist 2.1.0 (2020-08-25)
===============================

Features
--------

- `#585 <https://github.com/pytest-dev/pytest-xdist/issues/585>`_: New ``pytest_xdist_auto_num_workers`` hook can be implemented by plugins or ``conftest.py`` files to control the number of workers when ``--numprocesses=auto`` is given in the command-line.


Trivial Changes
---------------

- `#585 <https://github.com/pytest-dev/pytest-xdist/issues/585>`_: ``psutil`` has proven to make ``pytest-xdist`` installation in certain platforms and containers problematic, so to use it for automatic number of CPUs detection users need to install the ``psutil`` extra::

      pip install pytest-xdist[psutil]


pytest-xdist 2.0.0 (2020-08-12)
===============================

Deprecations and Removals
-------------------------

- `#541 <https://github.com/pytest-dev/pytest-xdist/issues/541>`_: Drop backward-compatibility "slave" aliases related to worker nodes.  We deliberately moved away from this terminology years ago, and it seems like the right time to finish the deprecation and removal process.

- `#569 <https://github.com/pytest-dev/pytest-xdist/issues/569>`_: ``pytest-xdist`` no longer supports Python 2.7.


Features
--------

- `#504 <https://github.com/pytest-dev/pytest-xdist/issues/504>`_: New functions ``xdist.is_xdist_worker``, ``xdist.is_xdist_master``, ``xdist.get_xdist_worker_id``, to easily identify the current node.


Bug Fixes
---------

- `#471 <https://github.com/pytest-dev/pytest-xdist/issues/471>`_: Fix issue with Rsync reporting in quiet mode.

- `#553 <https://github.com/pytest-dev/pytest-xdist/issues/553>`_: When using ``-n auto``, count the number of physical CPU cores instead of logical ones.


Trivial Changes
---------------

- `#541 <https://github.com/pytest-dev/pytest-xdist/issues/541>`_: ``pytest-xdist`` now requires ``pytest>=6.0``.


pytest-xdist 1.34.0 (2020-07-27)
================================

Features
--------

- `#549 <https://github.com/pytest-dev/pytest-xdist/issues/549>`_: Make ``--pdb`` imply ``--dist no``, as the two options cannot really work together at the moment.


Bug Fixes
---------

- `#478 <https://github.com/pytest-dev/pytest-xdist/issues/478>`_: Fix regression with duplicated arguments via $PYTEST_ADDOPTS in 1.30.0.

- `#558 <https://github.com/pytest-dev/pytest-xdist/issues/558>`_: Fix ``rsyncdirs`` usage with pytest 6.0.

- `#562 <https://github.com/pytest-dev/pytest-xdist/issues/562>`_: Do not trigger the deprecated ``pytest_warning_captured`` in pytest 6.0+.


pytest-xdist 1.33.0 (2020-07-09)
================================

Features
--------

- `#554 <https://github.com/pytest-dev/pytest-xdist/issues/554>`_: Fix warnings support for upcoming pytest 6.0.


Trivial Changes
---------------

- `#548 <https://github.com/pytest-dev/pytest-xdist/issues/548>`_: SCM and CI files are no longer included in the source distribution.


pytest-xdist 1.32.0 (2020-05-03)
================================

Deprecations and Removals
-------------------------

- `#475 <https://github.com/pytest-dev/pytest-xdist/issues/475>`_: Drop support for EOL Python 3.4.


Features
--------

- `#524 <https://github.com/pytest-dev/pytest-xdist/issues/524>`_: Add `testrun_uid` fixture. This is a shared value that uniquely identifies a test run among all workers.
  This also adds a `PYTEST_XDIST_TESTRUNUID` environment variable that is accessible within a test as well as a command line option `--testrunuid` to manually set the value from outside.


pytest-xdist 1.31.0 (2019-12-19)
================================

Features
--------

- `#486 <https://github.com/pytest-dev/pytest-xdist/issues/486>`_: Add support for Python 3.8.


Bug Fixes
---------

- `#491 <https://github.com/pytest-dev/pytest-xdist/issues/491>`_: Fix regression that caused custom plugin command-line arguments to be discarded when using ``--tx`` mode.



pytest-xdist 1.30.0 (2019-10-01)
================================

Features
--------

- `#448 <https://github.com/pytest-dev/pytest-xdist/issues/448>`_: Initialization between workers and master nodes is now more consistent, which fixes a number of
  long-standing issues related to startup with the ``-c`` option.

  Issues:

  * `#6 <https://github.com/pytest-dev/pytest-xdist/issues/6>`__: Poor interaction between ``-n#`` and ``-c X.cfg``
  * `#445 <https://github.com/pytest-dev/pytest-xdist/issues/445>`__: pytest-xdist is not reporting the same nodeid as pytest does

  This however only works with **pytest 5.1 or later**, as it required changes in pytest itself.


Bug Fixes
---------

- `#467 <https://github.com/pytest-dev/pytest-xdist/issues/467>`_: Fix crash issues related to running xdist with the terminal plugin disabled.


pytest-xdist 1.29.0 (2019-06-14)
================================

Features
--------

- `#226 <https://github.com/pytest-dev/pytest-xdist/issues/226>`_: ``--max-worker-restart`` now assumes a more reasonable value (4 times the number of
  nodes) when not given explicitly. This prevents test suites from running forever when the suite crashes during collection.

- `#435 <https://github.com/pytest-dev/pytest-xdist/issues/435>`_: When the test session is interrupted due to running out of workers, the reason is shown in the test summary
  for easier viewing.

- `#442 <https://github.com/pytest-dev/pytest-xdist/issues/442>`_: Compatibility fix for upcoming pytest 5.0: ``session.exitstatus`` is now an ``IntEnum`` object.


Bug Fixes
---------

- `#435 <https://github.com/pytest-dev/pytest-xdist/issues/435>`_: No longer show an internal error when we run out of workers due to crashes.


pytest-xdist 1.28.0 (2019-04-02)
================================

Features
--------

- `#426 <https://github.com/pytest-dev/pytest-xdist/issues/426>`_: ``pytest-xdist`` now uses the new ``pytest_report_to_serializable`` and ``pytest_report_from_serializable``
  hooks from ``pytest 4.4`` (still experimental). This will make report serialization more reliable and
  extensible.

  This also means that ``pytest-xdist`` now requires ``pytest>=4.4``.


pytest-xdist 1.27.0 (2019-02-15)
================================

Features
--------

- `#374 <https://github.com/pytest-dev/pytest-xdist/issues/374>`_: The new ``pytest_xdist_getremotemodule`` hook allows overriding the module run on remote nodes.

- `#415 <https://github.com/pytest-dev/pytest-xdist/issues/415>`_: Improve behavior of ``--numprocesses=auto`` to work well with ``--pdb`` option.


pytest-xdist 1.26.1 (2019-01-28)
================================

Bug Fixes
---------

- `#406 <https://github.com/pytest-dev/pytest-xdist/issues/406>`_: Do not implement deprecated ``pytest_logwarning`` hook in pytest versions where it is deprecated.


pytest-xdist 1.26.0 (2019-01-11)
================================

Features
--------

- `#376 <https://github.com/pytest-dev/pytest-xdist/issues/376>`_: The current directory is no longer added ``sys.path`` for local workers, only for remote connections.

  This behavior is surprising because it makes xdist runs and non-xdist runs to potentially behave differently.


Bug Fixes
---------

- `#379 <https://github.com/pytest-dev/pytest-xdist/issues/379>`_: Warning attributes are checked to make sure they can be dumped prior to
  serializing the warning for submission to the master node.


pytest-xdist 1.25.0 (2018-12-12)
================================

Deprecations and Removals
-------------------------

- `#372 <https://github.com/pytest-dev/pytest-xdist/issues/372>`_: Pytest versions older than 3.6 are no longer supported.


Features
--------

- `#373 <https://github.com/pytest-dev/pytest-xdist/issues/373>`_: Node setup information is hidden when pytest is run in quiet mode to reduce noise on many-core machines.

- `#388 <https://github.com/pytest-dev/pytest-xdist/issues/388>`_: ``mainargv`` is made available in ``workerinput`` from the host's ``sys.argv``.

  This can be used via ``request.config.workerinput["mainargv"]``.


Bug Fixes
---------

- `#332 <https://github.com/pytest-dev/pytest-xdist/issues/332>`_: Fix report of module-level skips (``pytest.skip(reason, allow_module_level=True)``).

- `#378 <https://github.com/pytest-dev/pytest-xdist/issues/378>`_: Fix support for gevent monkeypatching

- `#384 <https://github.com/pytest-dev/pytest-xdist/issues/384>`_: pytest 4.1 support: ``ExceptionInfo`` API changes.

- `#390 <https://github.com/pytest-dev/pytest-xdist/issues/390>`_: pytest 4.1 support: ``pytest_logwarning`` hook removed.


pytest-xdist 1.24.1 (2018-11-09)
================================

Bug Fixes
---------

- `#349 <https://github.com/pytest-dev/pytest-xdist/issues/349>`_: Correctly handle warnings created with arguments that can't be serialized during the transfer from workers to master node.


pytest-xdist 1.24.0 (2018-10-18)
================================

Features
--------

- `#337 <https://github.com/pytest-dev/pytest-xdist/issues/337>`_: New ``--maxprocesses`` command-line option that limits the maximum number of workers when using ``--numprocesses=auto``.


Bug Fixes
---------

- `#351 <https://github.com/pytest-dev/pytest-xdist/issues/351>`_: Fix scheduling deadlock in case of inter-test locking.


pytest-xdist 1.23.2 (2018-09-28)
================================

Bug Fixes
---------

- `#344 <https://github.com/pytest-dev/pytest-xdist/issues/344>`_: Fix issue where Warnings could cause pytest to fail if they do not set the args attribute correctly.


pytest-xdist 1.23.1 (2018-09-25)
================================

Bug Fixes
---------

- `#341 <https://github.com/pytest-dev/pytest-xdist/issues/341>`_: Fix warnings transfer between workers and master node with pytest >= 3.8.


pytest-xdist 1.23.0 (2018-08-23)
================================

Features
--------

- `#330 <https://github.com/pytest-dev/pytest-xdist/issues/330>`_: Improve collection performance by reducing the number of events sent to ``master`` node.


pytest-xdist 1.22.5 (2018-07-27)
================================

Bug Fixes
---------

- `#321 <https://github.com/pytest-dev/pytest-xdist/issues/321>`_: Revert change that dropped support for ``pytest<3.4`` and require ``six``.

  This change caused problems in some installations, and was a mistaken
  in the first place as we should not change version requirements
  in bug-fix releases unless they fix an actual bug.


pytest-xdist 1.22.4 (2018-07-27)
================================

Bug Fixes
---------

- `#305 <https://github.com/pytest-dev/pytest-xdist/issues/305>`_: Remove last references to obsolete ``py.code``.

  Remove some unnecessary references to ``py.builtin``.

- `#316 <https://github.com/pytest-dev/pytest-xdist/issues/316>`_: Workaround cpu detection on Travis CI.


pytest-xdist 1.22.3 (2018-07-23)
================================

Bug Fixes
---------

- Fix issue of virtualized or containerized environments not reporting the number of CPUs correctly. (`#9 <https://github.com/pytest-dev/pytest-xdist/issues/9>`_)


Trivial Changes
---------------

- Make all classes subclass from ``object`` and fix ``super()`` call in ``LoadFileScheduling``; (`#297 <https://github.com/pytest-dev/pytest-xdist/issues/297>`_)


pytest-xdist 1.22.2 (2018-02-26)
================================

  start if the first scope had only one test. (`#257
  <https://github.com/pytest-dev/pytest-xdist/issues/257>`_)


Trivial Changes
---------------

- Change terminology used by ``pytest-xdist`` to *master* and *worker* in
  arguments and messages (for example ``--max-worker-reset``). (`#234
  <https://github.com/pytest-dev/pytest-xdist/issues/234>`_)


pytest-xdist 1.22.0 (2018-01-11)
================================

Features

- Drop support for EOL Python 2.6. (`#259
  <https://github.com/pytest-dev/pytest-xdist/issues/259>`_)


Features
--------

- New ``--dist=loadfile`` option which load-distributes test to workers grouped
  by the file the tests live in. (`#242
  <https://github.com/pytest-dev/pytest-xdist/issues/242>`_)


Bug Fixes
---------

- Fix accidental mutation of test report during serialization causing longrepr
  string-ification to break. (`#241
  <https://github.com/pytest-dev/pytest-xdist/issues/241>`_)


pytest-xdist 1.20.1 (2017-10-05)
================================

Bug Fixes
---------

- Fix hang when all worker nodes crash and restart limit is reached (`#45
  <https://github.com/pytest-dev/pytest-xdist/issues/45>`_)

- Fix issue where the -n option would still run distributed tests when pytest
  was run with the --collect-only option (`#5
  <https://github.com/pytest-dev/pytest-xdist/issues/5>`_)


pytest-xdist 1.20.0 (2017-08-17)
================================

Features
--------

- ``xdist`` now supports tests to log results multiple times, improving
  integration with plugins which require it like `pytest-rerunfailures
  <https://github.com/gocept/pytest-rerunfailures>`_ and `flaky
  <https://pypi.python.org/pypi/flaky>`_. (`#206 <https://github.com/pytest-
  dev/pytest-xdist/issues/206>`_)


Bug Fixes
---------

- Fix issue where tests were being incorrectly identified if a worker crashed
  during the ``teardown`` stage of the test. (`#124 <https://github.com/pytest-
  dev/pytest-xdist/issues/124>`_)


pytest-xdist 1.19.1 (2017-08-10)
================================

Bug Fixes
---------

- Fix crash when transferring internal pytest warnings from workers to the
  master node. (`#214 <https://github.com/pytest-dev/pytest-
  xdist/issues/214>`_)


pytest-xdist 1.19.0 (2017-08-09)
================================

Deprecations and Removals
-------------------------

- ``--boxed`` functionality has been moved to a separate plugin, `pytest-forked
  <https://github.com/pytest-dev/pytest-forked>`_. This release now depends on
  `` pytest-forked`` and provides ``--boxed`` as a backward compatibility
  option. (`#1 <https://github.com/pytest-dev/pytest-xdist/issues/1>`_)


Features
--------

- New ``--dist=loadscope`` option: sends group of related tests to the same
  worker. Tests are grouped by module for test functions and by class for test
  methods. See ``README.rst`` for more information. (`#191 <https://github.com
  /pytest-dev/pytest-xdist/issues/191>`_)

- Warnings are now properly transferred from workers to the master node. (`#92
  <https://github.com/pytest-dev/pytest-xdist/issues/92>`_)


Bug Fixes
---------

  <https://github.com/pytest-dev/pytest-xdist/issues/196>`_)


pytest-xdist 1.18.2 (2017-07-28)
================================

Bug Fixes
---------

- Removal of unnecessary dependency on incorrect version of py. (`#105
  <https://github.com/pytest-dev/pytest-xdist/issues/105>`_)

- Fix bug in internal event-loop error handler in the master node. This bug
  would shadow the original errors making extremely hard/impossible for users
  to diagnose the problem properly. (`#175 <https://github.com/pytest-
  dev/pytest-xdist/issues/175>`_)


pytest-xdist 1.18.1 (2017-07-05)
================================

Bug Fixes
---------

- Fixed serialization of ``longrepr.sections`` during error reporting from
  workers. (`#171 <https://github.com/pytest-dev/pytest-xdist/issues/171>`_)

- Fix ``ReprLocal`` not being unserialized breaking --showlocals usages. (`#176
  <https://github.com/pytest-dev/pytest-xdist/issues/176>`_)


pytest-xdist 1.18.0 (2017-06-26)
================================

- ``pytest-xdist`` now requires ``pytest>=3.0.0``.

Features
--------

- Add long option `--numprocesses` as alternative for `-n`. (#168)


Bug Fixes
---------

- Fix serialization and deserialization dropping longrepr details. (#133)


pytest-xdist 1.17.1 (2017-06-10)
================================

Bug Fixes
---------

- Hot fix release reverting the change introduced by #124, unfortunately it
  broke a number of test suites so we are reversing this change while we
  investigate the problem. (#157)


Improved Documentation
----------------------

- Introduced ``towncrier`` for ``CHANGELOG`` management. (#154)

- Added ``HOWTORELEASE`` documentation. (#155)


1.17.0
------

- fix #124: xdist would mark test as complete after 'call' step. As a result,
  xdist could identify the wrong test as failing when test crashes at teardown.
  To address this issue, xdist now marks test as complete at teardown.

1.16.0
------

- ``pytest-xdist`` now requires pytest 2.7 or later.

- Add ``worker_id`` attribute in the TestReport

- new hook: ``pytest_xdist_make_scheduler(config, log)``, can return custom tests items
  distribution logic implementation. You can take a look at built-in ``LoadScheduling``
  and ``EachScheduling`` implementations. Note that required scheduler class public
  API may change in next ``pytest-xdist`` versions.

1.15.0
------

- new ``worker_id`` fixture, returns the id of the worker in a test or fixture.
  Thanks Jared Hellman for the PR.

- display progress during collection only when in a terminal, similar to pytest #1397 issue.
  Thanks Bruno Oliveira for the PR.

- fix internal error message when ``--maxfail`` is used (#62, #65).
  Thanks Collin RM Stocks and Bryan A. Jones for reports and Bruno Oliveira for the PR.


1.14
----

- new hook: ``pytest_xdist_node_collection_finished(node, ids)``, called when
  a worker has finished collection. Thanks Omer Katz for the request and
  Bruno Oliveira for the PR.

- fix README display on pypi

- fix #22: xdist now works if the internal tmpdir plugin is disabled.
  Thanks Bruno Oliveira for the PR.

- fix #32: xdist now works if looponfail or boxed are disabled.
  Thanks Bruno Oliveira for the PR.


1.13.1
-------

- fix a regression -n 0 now disables xdist again


1.13
-------------------------

- extended the tox matrix with the supported py.test versions

- split up the plugin into 3 plugin's
  to prepare the departure of boxed and looponfail.

  looponfail will be a part of core
  and forked boxed will be replaced
  with a more reliable primitive based on xdist

- conforming with new pytest-2.8 behavior of returning non-zero when all
  tests were skipped or deselected.

- new "--max-slave-restart" option that can be used to control maximum
  number of times pytest-xdist can restart slaves due to crashes. Thanks to
  Anatoly Bubenkov for the report and Bruno Oliveira for the PR.

- release as wheel

- "-n" option now can be set to "auto" for automatic detection of number
  of cpus in the host system. Thanks Suloev Dmitry for the PR.

1.12
-------------------------

- fix issue594: properly report errors when the test collection
  is random.  Thanks Bruno Oliveira.

- some internal test suite adaptation (to become forward
  compatible with the upcoming pytest-2.8)


1.11
-------------------------

- fix pytest/xdist issue485 (also depends on py-1.4.22):
  attach stdout/stderr on --boxed processes that die.

- fix pytest/xdist issue503: make sure that a node has usually
  two items to execute to avoid scoped fixtures to be torn down
  pre-maturely (fixture teardown/setup is "nextitem" sensitive).
  Thanks to Andreas Pelme for bug analysis and failing test.

- restart crashed nodes by internally refactoring setup handling
  of nodes.  Also includes better code documentation.
  Many thanks to Floris Bruynooghe for the complete PR.


1.10
-------------------------

- add glob support for rsyncignores, add command line option to pass
  additional rsyncignores. Thanks Anatoly Bubenkov.

- fix pytest issue382 - produce "pytest_runtest_logstart" event again
  in master. Thanks Aron Curzon.

- fix pytest issue419 by sending/receiving indices into the test
  collection instead of node ids (which are not necessarily unique
  for functions parametrized with duplicate values)

- send multiple "to test" indices in one network message to a slave
  and improve heuristics for sending chunks where the chunksize
  depends on the number of remaining tests rather than fixed numbers.
  This reduces the number of master -> node messages (but not the
  reverse direction)


1.9
-------------------------

- changed LICENSE to MIT

- fix duplicate reported test ids with --looponfailing
  (thanks Jeremy Thurgood)

- fix pytest issue41: re-run tests on all file changes, not just
  randomly select ones like .py/.c.

- fix pytest issue347: slaves running on top of Python3.2
  will set PYTHONDONTWRITEYBTECODE to 1 to avoid import concurrency
  bugs.

1.8
-------------------------

- fix pytest-issue93 - use the refined pytest-2.2.1 runtestprotocol
  interface to perform eager teardowns for test items.

1.7
-------------------------

- fix incompatibilities with pytest-2.2.0 (allow multiple
  pytest_runtest_logreport reports for a test item)

1.6
-------------------------

- terser collection reporting

- fix issue34 - distributed testing with -p plugin now works correctly

- fix race condition in looponfail mode where a concurrent file removal
  could cause a crash

1.5
-------------------------

- adapt to and require pytest-2.0 changes, rsyncdirs and rsyncignore can now
  only be specified in [pytest] sections of ini files, see "py.test -h"
  for details.
- major internal refactoring to match the pytest-2.0 event refactoring
  - perform test collection always at slave side instead of at the master
  - make python2/python3 bridging work, remove usage of pickling
- improve initial reporting by using line-rewriting
- remove all trailing whitespace from source

1.4
-------------------------

- perform distributed testing related reporting in the plugin
  rather than having dist-related code in the generic py.test
  distribution

- depend on execnet-1.0.7 which adds "env1:NAME=value" keys to
  gateway specification strings.

- show detailed gateway setup and platform information only when
  "-v" or "--verbose" is specified.

1.3
-------------------------

- fix --looponfailing - it would not actually run against the fully changed
  source tree when initial conftest files load application state.

- adapt for py-1.3.1's new --maxfailure option

1.2
-------------------------

- fix issue79: sessionfinish/teardown hooks are now called systematically
  on the slave side
- introduce a new data input/output mechanism to allow the master side
  to send and receive data from a slave.
- fix race condition in underlying pickling/unpickling handling
- use and require new register hooks facility of py.test>=1.3.0
- require improved execnet>=1.0.6 because of various race conditions
  that can arise in xdist testing modes.
- fix some python3 related pickling related race conditions
- fix PyPI description

1.1
-------------------------

- fix an indefinite hang which would wait for events although no events
  are pending - this happened if items arrive very quickly while
  the "reschedule-event" tried unconditionally avoiding a busy-loop
  and not schedule new work.

1.0
-------------------------

- moved code out of py-1.1.1 into its own plugin
- use a new, faster and more sensible model to do load-balancing
  of tests - now no magic "MAXITEMSPERHOST" is needed and load-testing
  works effectively even with very few tests.
- cleaned up termination handling
- make -x cause hard killing of test nodes to decrease wait time
  until the traceback shows up on first failure
