+==================
+
+* pytest no longer generates ``PendingDeprecationWarning`` from its own operations, which was introduced by mistake in version ``3.0.5`` (`#2118`_).
+  Thanks to `@nicoddemus`_ for the report and `@RonnyPfannschmidt`_ for the PR.
+
+
 * pytest no longer recognizes coroutine functions as yield tests (`#2129`_).
   Thanks to `@malinoff`_ for the PR.
 
+* Plugins loaded by the ``PYTEST_PLUGINS`` environment variable are now automatically
+  considered for assertion rewriting (`#2185`_).
+  Thanks `@nicoddemus`_ for the PR.
+
 * Improve error message when pytest.warns fails (`#2150`_). The type(s) of the
   expected warnings and the list of caught warnings is added to the
   error message. Thanks `@lesteve`_ for the PR.
 
+* Fix ``pytester`` internal plugin to work correctly with latest versions of
+  ``zope.interface`` (`#1989`_). Thanks `@nicoddemus`_ for the PR.
+
+* Assert statements of the ``pytester`` plugin again benefit from assertion rewriting (`#1920`_).
+  Thanks `@RonnyPfannschmidt`_ for the report and `@nicoddemus`_ for the PR.
+
 * Specifying tests with colons like ``test_foo.py::test_bar`` for tests in
   subdirectories with ini configuration files now uses the correct ini file
   (`#2148`_).  Thanks `@pelme`_.
 
-*
+* Fail ``testdir.runpytest().assert_outcomes()`` explicitly if the pytest
+  terminal output it relies on is missing. Thanks to `@eli-b`_ for the PR.
