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
---------

- Fix serialization of native tracebacks (``--tb=native``). (`#196
  <https://github.com/pytest-dev/pytest-xdist/issues/196>`_)
