 * Fix regression, pytest now skips unittest correctly if run with ``--pdb``
   (`#2137`_). Thanks to `@gst`_ for the report and `@mbyt`_ for the PR.
 
+* Ignore exceptions raised from descriptors (e.g. properties) during Python test collection (`#2234`_).
+  Thanks to `@bluetech`_.
+  
+*  
+
 * Replace ``raise StopIteration`` usages in the code by simple ``returns`` to finish generators, in accordance to `PEP-479`_ (`#2160`_).
   Thanks `@tgoodlet`_ for the report and `@nicoddemus`_ for the PR.

-*
+* Skipping plugin now also works with test items generated by custom collectors (`#2231`_).
+  Thanks to `@vidartf`_.
+  
+*  
 
-*
+* Conditionless ``xfail`` markers no longer rely on the underlying test item
+  being an instance of ``PyobjMixin``, and can therefore apply to tests not
+  collected by the built-in python test collector. Thanks `@barneygale`_ for the
+  PR.
