+New Turbo colormap
+------------------
+
+Turbo is an improved rainbow colormap for visualization, created by the Google
+AI team for computer visualization and machine learning. Its purpose is to
+display depth and disparity data. Please see the `Google AI Blog
+<https://ai.googleblog.com/2019/08/turbo-improved-rainbow-colormap-for.html>`_
+for further details.
+
+Below shows Turbo and some other rainbow-esque colormaps:

+Better control of ``Axes.pie`` normalization
+--------------------------------------------
+
+Previously, `.Axes.pie` would normalize its input *x* if ``sum(x) > 1``, but
+would do nothing if the sum were less than 1. This can be confusing, so an
+explicit keyword argument *normalize* has been added. By default, the old
+behavior is preserved.
+
+By passing *normalize*, one can explicitly control whether any rescaling takes
+place and whether partial pies should be created.

 Simple syntax to select fonts by absolute path
 ----------------------------------------------
 
 Fonts can now be selected by passing an absolute `pathlib.Path` to the *font*
 keyword argument of `.Text`.
 
 
+Improved font weight detection
+------------------------------
+
+Matplotlib is now better able to determine the weight of fonts from their
+metadata, allowing to differentiate between fonts within the same family more
+accurately.

 Interactive tool improvements
 -----------------------------
 
+More consistent toolbar behavior across backends
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Toolbar features are now more consistent across backends. The history buttons
+will auto-disable when there is no further action in a direction. The pan and
+zoom buttons will be marked active when they are in use.
+
+In NbAgg and WebAgg, the toolbar buttons are now grouped similarly to other
+backends. The WebAgg toolbar now uses the same icons as other backends.
+
+Toolbar icons are now styled for dark themes
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+On dark themes, toolbar icons will now be inverted. When using the GTK3Agg
+backend, toolbar icons are now symbolic, and both foreground and background
+colors will follow the theme. Tooltips should also behave correctly.
+
 Cursor text now uses a number of significant digits matching pointing precision

+SVG supports URLs on more artists

+
+URLs on more artists (i.e., from `.Artist.set_url`) will now be saved in
+SVG files, namely, ``Tick``\s and ``Line2D``\s are now supported.
