Removed rcParams
2+
````````````````
3+
4+
The following deprecated rcParams are removed:
5+
6+
- ``text.dvipnghack``,
7+
- ``nbagg.transparent`` (use :rc:`figure.facecolor` instead),
8+
- ``plugins.directory``,
9+
- ``axes.hold``,
10+
- ``backend.qt4`` and ``backend.qt5`` (set the :envvar:`QT_API` environment
11+
variable instead).
12+
13+
The associated validator functions ``rcsetup.validate_qt4`` and
14+
``validate_qt5`` are deprecated.
