 A new API to access markers has been introduced in pytest 3.6 in order to solve the problems with the initial design, providing :func:`_pytest.nodes.Node.iter_markers` method to iterate over markers in a consistent manner and reworking the internals, which solved great deal of problems with the initial design.
 
+Here is a non-exhaustive list of issues fixed by the new implementation:
+
+
+* Marks don't pick up nested classes (`#199 <https://github.com/pytest-dev/pytest/issues/199>`_).
+
+* markers stains on all related classes (`#568 <https://github.com/pytest-dev/pytest/issues/568>`_).
+
+* combining marks - args and kwargs calculation (`#2897 <https://github.com/pytest-dev/pytest/issues/2897>`_).
+
+* ``request.node.get_marker('name')`` returns ``None`` for markers applied in classes (`#902 <https://github.com/pytest-dev/pytest/issues/902>`_).
+
+* marks applied in parametrize are stored as markdecorator (`#2400 <https://github.com/pytest-dev/pytest/issues/2400>`_).
+
+* fix marker interaction in a backward incompatible way (`#1670 <https://github.com/pytest-dev/pytest/issues/1670>`_).
+
+* Refactor marks to get rid of the current "marks transfer" mechanism (`#2363 <https://github.com/pytest-dev/pytest/issues/2363>`_).
+
+* Introduce FunctionDefinition node, use it in generate_tests (`#2522 <https://github.com/pytest-dev/pytest/issues/2522>`_).
+
+* remove named marker attributes and collect markers in items (`#891 <https://github.com/pytest-dev/pytest/issues/891>`_).
+
+* skipif mark from parametrize hides module level skipif mark (`#1540 <https://github.com/pytest-dev/pytest/issues/1540>`_).
+
+* skipif + parametrize not skipping tests (`#1296 <https://github.com/pytest-dev/pytest/issues/1296>`_).
+
+* marker transfer incompatible with inheritance (`#535 <https://github.com/pytest-dev/pytest/issues/535>`_).
+

 .. note::
 
 	in a future major relase of pytest we will introduce class based markers,
