Arguments

• Axes.text() / pyplot.text() do not support the parameter withdash anymore. Use Axes.annotate() and pyplot.annotate() instead.
• The first parameter of matplotlib.use has been renamed from arg to backend (only relevant if you pass by keyword).
• The parameter warn of matplotlib.use has been removed. A failure to switch the backend will now always raise an ImportError if force is set; catch that error if necessary.
• All parameters of matplotlib.use except the first one are now keyword-only.
• The unused parameters shape and imlim of imshow() are now removed. All parameters beyond extent are now keyword-only.
• The unused parameter interp_at_native of BboxImage has been removed.
• The parameter usetex of TextToPath.get_text_path has been removed. Use ismath='TeX' instead.
• The parameter block of show() is now keyword-only, and arbitrary arguments or keyword arguments are no longer accepted.
• The parameter frameon of Figure.savefig has been removed. Use facecolor="none" to get a transparent background.
• Passing a wx.EvtHandler as the first argument to backend_wx.TimerWx is not supported anymore; the signature of TimerWx is now consistent with TimerBase.
• The manage_xticks parameter of boxplot and bxp has been renamed to manage_ticks.
• The normed parameter of hist2d has been renamed to density.
• The s parameter of Annotation has been renamed to text.
• For all functions in bezier that supported a tolerence parameter, this parameter has been renamed to tolerance.
• axis("normal") is not supported anymore. Use the equivalent axis("auto") instead.
• axis() does not accept arbitrary keyword arguments anymore.
• Axis.set_ticklabels() does not accept arbitrary positional arguments other than ticklabels.
• mpl_toolkits.mplot3d.art3d.Poly3DCollection.set_zsort does not accept the value True anymore. Pass the equivalent value 'average' instead.
• AnchoredText no longer accepts horizontalalignment or verticalalignment keyword arguments.
• ConnectionPatch no longer accepts the arrow_transmuter and connector keyword arguments, which did nothing since 3.0.
• FancyArrowPatch no longer accepts the arrow_transmuter and connector keyword arguments, which did nothing since 3.0.
• TextPath no longer accepts arbitrary positional or keyword arguments.
• MaxNLocator.set_params() no longer accepts arbitrary keyword arguments.
• pie no longer accepts and squeezes non-1D inputs; pass 1D input to the x argument.
• Passing (n, 1)-shaped error arrays to Axes.errorbar() is no longer supported; pass a 1D array instead.

rcParams

• The text.latex.unicode rcParam has been removed, with no replacement. Matplotlib now always supports unicode in usetex.
• The savefig.frameon rcParam has been removed. Set rcParams["savefig.facecolor"] (default: 'auto') to "none" to get a transparent background.
• The pgf.debug, verbose.fileo and verbose.verbose.level rcParams, which had no effect, have been removed.
• Support for setting rcParams["mathtext.default"] (default: 'it') to "circled" has been removed.

Environment variables

• MATPLOTLIBDATA (no replacement).

mathtext

• The \stackrel command (which behaved differently from its LaTeX version) has been removed. Use \genfrac instead.
• The \mathcircled command has been removed. Directly use Unicode characters, such as '\N{CIRCLED LATIN CAPITAL LETTER A}', instead.
