The following lists past and future (where dates are replaced with ##) changes to ProPlot. Authors are shown next to each change. Where not indicated, Luke Davis was the author.

See the :ref:`author page <authors>` for a list of contributors, and see the :ref:`contribution guide <contributions>` if you are interested in submitting your own changes.

This will be published when some major refactoring tasks are completed, and deprecation warnings will be removed. See :pr:`89`, :pr:`109`, :pr:`110`, and :pr:`111`.

Deprecated

• Deprecate ~proplot.axes.Axes.format functions in favor of the axes-artist ~matplotlib.artist.Artist.set override (:pr:`89`).

Features

• All ~proplot.axes.Axes.format features are now implemented with individual setters, like in matplotlib, but we still encourage using the bulk set method through documentation examples and by populating the set docstring (so valid arguments are no longer implicit).
• Users can now use ~proplot.subplots.figure with ~proplot.subplots.Figure.add_subplot as an alternative to the recommended ~proplot.subplots.subplots workflow (:pr:`110`). This is a major improvement!
• ~proplot.subplots.GridSpec now accepts physical units, rather than having ~proplot.subplots.subplots handle the units (:pr:`110`).
• Allow "hanging" twin x and y axes as members of the ~proplot.subplots.EdgeStack container. Arbitrarily many siblings are now permitted.
• Use ~proplot.subplots.GeometrySolver for calculating various automatic layout stuff instead of having 1000 hidden ~proplot.subplots.Figure methods (:pr:`110`).
• Use ~proplot.subplots.EdgeStack class for handling stacks of colorbars, legends, and text (:pr:`110`).

Internals

• Add comprehensive unit tests and migrate from Travis CI to Github Actions.
• Validate assignments to ~proplot.config.RcConfigurator and turn the configurator into a monkey patch of ~matplotlib.rcParams (:pr:`109`).
• Implement and document plotting wrappers (e.g. ~proplot.wrappers.standardize_1d) on the individual methods themselves (e.g. ~proplot.axes.Axes.plot; :pr:`111`). This is much easier for users.
• Handle all projection keyword arguments in ~proplot.subplots.Figure.add_subplot instead of ~proplot.subplots.subplots (:pr:`110`).
• Panels, colorbars, and legends are now members of ~proplot.subplots.EdgeStack stacks rather than getting inserted directly into the main ~proplot.subplots.GridSpec (:pr:`110`).

Bug fixes

• Fix issue where deprecated aspect ~proplot.ui.subplots argument is ignored (:commit:`70a8b87d`).
• Fix issue where ~proplot.axes.Axes.parametric ignores interp when selecting DiscreteNorm colormap levels (:commit:`152a3a81`).
• Ensure plot returns tuples of handles instead of lists, and ensure indicate_error returns a singleton tuple containing (line, error) objects (:issue:`260`).
• Fix issue where a-b-c labels are removed in presence of 'top' panels with titleabove=True (:commit:`7873d5e0`).
• Fix issue where thin pyplot-function wrappers e.g. isinteractive do not return results (:commit:`e62e3655`).

Features

• Add pad keyword to legend, colorbar, and panel that controls tight layout padding, analogous to space (:pr:`###`).
• Fix wequal and hequal so they only work between main subplot rows and columns instead of panels.
• Allow variable tight layout padding between subplot panels using wpad and hpad, analogous to wspace and hspace (:pr:`###`).
• Support XDG directories for proplot configuration files, emit warnings if multiple paths found (:issue:`###`).
• Add public ~proplot.config.RcConfigurator.user_file and ~proplot.config.RcConfigurator.user_folder methods for displaying folder locations (:commit:`b11d744a`).
• Add :rcraw:`colorbar.facecolor` and :rcraw:`colorbar.edgecolor` properties analogous to legend properties for controlling frame (:pr:`264`).
• Allow list-of-list "centered row" legend specification with e.g. [h, [h1, h2, h3]] (i.e., mixed list and non-list input) (:pr:`264`).
• Permit partial specification of labels with "centered rows", e.g. labels=['label', None] can be combined with the above (:pr:`264`).
• Treat singleton lists and tuple legend input same as scalar handle input, i.e. never triggers "centered row" specification (:pr:`264`).
• Silently ignore non-artist and non-container input -- e.g., ignore the bins and values returned by hist (:pr:`264`).
• Support auto-detection of tuple-grouped legend handle labels when labels not passed explicitly (:pr:`264`).
• Automatically pull out grouped tuples of artists if they have differing labels (:pr:`264`). This is convenient for passing error indications to legend.
• Support more artist synonyms throughout plotting overrides, e.g. ec for edgecolor, lw for linewidth, fc and fillcolor for facecolor (:pr:`264`). This expands matplotlib synonyms.
• Support list-of-strings parametric coordinate and format on-the-fly colorbar ticks with those string labels (:commit:`02fbda45`).
• Add new :rcraw:`leftlabel.rotation`, :rcraw:`toplabel.rotation`, :rcraw:`rightlabel.rotation`, :rcraw:`bottomlabel.rotation` keywords, make default row label rotation match default y label rotation (:commit:`bae85113`).
• Make ~proplot.axes.colorbar_extras capture matplotlib-native format keyword as alias for formatter and ticklabels (:issue:`262`).
• Permit legends from mappables using ContourSet.legend_elements and Collection.legend_elements (:pr:`264`).
• Add stepx command analogous to plotx and histh, boxploth, and violinploth commands analogous to barh (:pr:`264`). Also add aliases.

Internals

• Convert all plotting wrappers to dedicated overrides of individual functions (:pr:`264`). This massively simplifies the internals and makes learning and adopting proplot much easier for new users.
• Use metaclasses to redirect internal plotting calls to native matplotlib methods (:pr:`264`). Much safer/more stable this way.
• Use metaclasses to efficiently impose defaults latlon=True and transform=PlateCarree() in 90% fewer lines (:pr:`264`).

Deprecated

• Remove v0.6.0 renamed classes (e.g. ProjAxes) from top-level namespace (:commit:`442e6aa6`). These were kept available just for documentation. The renamed functions shade, saturate, and inline_backend_fmt will be available until v0.8.
• Change default :rcraw:`savefig.transparent` back to False (:pr:`252`). Dubious justification for True in the first place, and makes default PNG proplot figures unreadable wherever "dark mode" is enabled.
• Rename SciVisColor colormaps from Blue1, Blue2, etc. to plurals Blues1, Blues2, etc. to avoid name conflict with open-color colors (:commit:`8be0473f`). Requesting the old names (case-sensitive) redirects to the new names (:commit:`3f0794d0`). This permits making monochromatic open-color maps with e.g. plot.Colormap('blue9') and feels more consistent with ColorBrewer convention of using plurals like Blues, Reds, etc.
• Shuffle various SciVisColor colormap names to make them consistent/succinct. Make Browns1 the most colorful/vibrant one, just like Greens1 and Blues1; split up the RedPurple maps into Reds and Purples; and add the Yellows category from the Oranges maps (:commit:`8be0473f`). Requesting the old names (case-sensitive) redirects to the new names (:commit:`3f0794d0`).
• Add :rcraw:`image.discrete` options and discrete keyword for toggling ~proplot.colors.DiscreteNorm application, and disable by default for imshow, matshow, spy, hexbin, and hist2d plots (:issue:`233`, :commit:`5a7e05e4`). Also make hexbin and hist2d behavior with discrete=True more sane by using maximum possible counts for autoscaling, and change ~proplot.colors.DiscreteNorm argument extend to more intuitive name unique.
• Rename :rcraw:`subplots.pad` and :rcraw:`subplots.axpad` to more intuitive :rcraw:`subplots.outerpad` and :rcraw:`subplots.innerpad` (:commit:`3c7a33a8`). Also rename ~proplot.figure.Figure keywords.
• Rename width and height ~proplot.subplots.subplots keyword args to figwidth and figheight to avoid confusion with refwidth/refheight (:commit:`12d01996`). Will accept old keyword args without warning since they are used heavily.
• Rename aspect, axwidth, and axheight keyword args to more intuitive refaspect, refwidth, and refheight (:commit:`12d01996`). Will accept old keyword args without warning since they are used heavily.
• Rename abovetop keyword for moving title/abc labels above top panels, colorbars, and legends to :rcraw:`title.above` (:commit:`9ceacb7b`). Example usage: ax.format(title='Title', titleabove=True).
• Rename the proplot.colors.PerceptuallyUniformColormap.from_color keyword shade to luminance, and add the saturation keyword (:commit:`3d8e7dd0`). These can also be passed to ~proplot.contructor.Colormap when it is called with positional arguments.
• Rename seldom-used Figure argument fallback_to_cm to more understandable mathtext_fallback (:pr:`251`).
• Reduce default :rcraw:`savefig.dpi` to 1000 (:commit:`bfda9c98`). Nature recommends 1000, Science recommends "more than 300", PNAS recommends 1000--1200. So 1000 is fine.
• Increase default :rcraw:`colorbar.insetpad` to avoid recurring issue where ticklabels run close to the background patch (:commit:`f5435976`)
• Use proplot TeX Gyre fonts with ~proplot.config.use_style styles unless specified otherwise (:commit:`6d7444fe`). Styles otherwise build on matplotlib defaults.
• When using medians=True or means=True with indicate_error plot simple error bars by default instead of bars and "boxes" (:commit:`4e30f415`). Only plot "boxes" with central "markers" by default for violin plots (:commit:`13b45ccd`).
• legend_extras no longer returns the background patch generated for centered-row legends (:pr:`254`). This is consistent with colorbar_extras not returning background patches generated for inset colorbars. Until proplot adds new subclasses, it makes more sense if these functions only return ~matplotlib.legend.Legend and ~matplotlib.colorbar.Colorbar instances.

Features

• Add the remaining commonly-used backend-related pyplot functions ion, ioff, isinteractive, and switch_backend to the top-level proplot namespace (:commit:`cd440155`). This avoids forcing users to import pyplot inside a proplot session (the remaining pyplot functions are related to the "non-object-oriented" workflow, which proplot explicitly discourages).
• Add support for local proplotrc files in addition to "hidden" .proplotrc files with leading dot (:commit:`8a989aca`).
• Add minimal support for "3D" ~matplotlib.mpl_toolkits.mplot3d.Axes3D axes (:issue:`249`). Example usage: fig.subplots(proj='3d').
• Add wequal, hequal, and equal options to still use automatic spacing but force the tight layout algorithm to make spacings equal (:pr:`215`, :issue:`64`) by Zachary Moon.
• Determine colormap levels using only in-bounds data if the x or y axis limits were explicitly set (:issue:`209`). Add inbounds ~proplot.axes.apply_cmap keyword and :rcraw:`image.inbounds` setting to control this.
• Allow calling proplot.colors.PerceptuallyUniformColormap.from_hsl by passing hue, saturation, or luminance to ~proplot.constructor.Colormap without any positional arguments (:commit:`3d8e7dd0`).
• Allow passing alpha, luminance, saturation to ~proplot.constructor.Colormap as lists to be applied to each component cmap (:commit:`3d8e7dd0`).
• Add convenient shorthands for channel references throughout colormap functions -- e.g. h for hue, l for luminance, etc. (:commit:`3d8e7dd0`).
• Add the 'Flare' and 'Crest' seaborn colormaps (:commit:`14bc16c9`). These are seaborn's color cycle-friendly alternatives to existing maps.
• Add the ~proplot.utils.shift_hue function analogous to scale_saturation and scale_luminance (:commit:`67488bb1`).
• Add the ~proplot.utils.to_hex function and make all color-manipulation funcs return HEX strings by default (:commit:`67488bb1`). Otherwise scatter throws warnings.
• Use 90 as the default luminance when creating monochromatic colormaps with to_listed set to True (as when ~proplot.constructor.Cycle calls ~proplot.constructor.Colormap; :commit:`3d8e7dd0`).
• Add ~proplot.axes.Axes.plotx and ~proplot.axes.Axes.scatterx commands that interpret plotting args as (y, x) rather than (x, y), analogous to ~proplot.axes.Axes.areax (:pr:`258`).
• Add support for ~proplot.axes.indicate_error horizontal error bars and shading for horizontal plotting commands barh, plotx, and scatterx (:pr:`258`).
• Add support for ax.plot_command('x_key', 'y_key', data=dataset) for virtually all plotting commands using standardize_1d and standardize_2d (:pr:`258`). This was an existing ~matplotlib.axes.Axes.plot feature.
• Add support for the plotting style ax.plot(x1, y1, fmt1, x2, y2, fmt2, ...) as allowed by matplotlib (:pr:`258`).
• Add absolute_width keyword to ~proplot.plot.bar_extras to make width argument absolute (:pr:`258`). Remains False by default.
• Use "sticky" edges in x-direction for lines drawn with plot() and in y-direction for lines drawn with plotx() (:pr:`258`). This eliminates padding along the "dependent" axis when limits are not specified, similar to histograms and barplots and matching a feature we previously added to fill_between (:pr:`166`).
• Add support for "stacked" plots to ~matplotlib.axes.Axes.vlines and ~matplotlib.axes.Axes.hlines (:pr:`258`).
• Add stack as alternative to stacked for bar and area plots (:commit:`4e30f415`). Imperative keywords are better.
• Allow passing e.g. barstds=3 or barpctiles=90 to request error bars denoting +/-3 standard deviations and 5-95 percentile range (:commit:`4e30f415`).
• Add singular indicate_error keywords barstd, barpctile, etc. as alternatives to barstds, barpctiles, etc. (:commit:`81151a58`). Also prefer them in the documentation.
• Permit different colors for ~matplotlib.axes.Axes.boxplot and ~matplotlib.axes.Axes.violinplot using color lists (:issue:`217`, :pr:`218`) by Mickaël Lalande. Also allow passing other args as lists (:commit:`4e30f415`).
• Allow passing means=True to boxplot to toggle mean line (:commit:`4e30f415`).
• Allow setting the mean and median boxplot linestyle with (mean|median)(ls|linestyle) keywords (:commit:`4e30f415`).
• Automatically set fill=True when passing a fill color or color(s) to boxplot_wrapper (:commit:`4e30f415`).
• Allow updating vlines and hlines styling with singular color and linestyle and all of their aliases (:pr:`258`).
• Allow updating axes fonts that use scalings like 'small' and 'large' by passing fontsize=N to format (:issue:`212`).
• Add titlebbox and abcbbox as alternatives to titleborder and abcborder for "inner" titles and a-b-c labels (:pr:`240`) by Pratiman Patel. Borders are still used by default.
• Allow putting title and abc in the same location -- the title and label are simply offset away from ech other (:issue:`402214f9`). Padding between them is controlled by the new param :rcraw:`abc.titlepad`.
• Add new :rcraw:`suptitle.pad`, :rcraw:`leftlabel.pad`, :rcraw:`toplabel.pad`, :rcraw:`bottomlabel.pad`, :rcraw:`rightlabel.pad` settings to control padding used when aligning super labels (:commit:`402214f9`). These can also be passed to ~proplot.axes.Axes.format and applied locally. The new defaults increase super title padding by a bit.
• More robust interpretation of :rcraw:`abc.style` -- now match case with first 'a' or 'A' in string, and only replace that one (:issue:`201`).
• Interpret fontsize-relative legend rc params like legend.borderpad with 'em' as default units rather than 'pt' (:commit:`6d98fd44`).
• Add :rcraw:`basemap` setting for changing the default backend (:commit:`c9ca0bdd`). If users have a cartopy vs. basemap preference, they probably want to use it globally.
• Add :rcraw:`cartopy.circular` setting for optionally disabling the "circular bounds on polar projections" feature (:commit:`c9ca0bdd`).
• Support the standard aliases 'ls', 'linestyle', 'linestyles', etc. in ~proplot.constructor.Cycle calls (:commit:`3d8e7dd0`).
• Add queue keyword to colorbar and legend to support workflow where users successively add handles to location (:pr:`254`).
• Add nozero keyword arg to apply_cmap to remove the zero contour from automatically generated levels (:commit:`10e0f13b`). Example usage: ax.contour(x, y, z, nozero=True).
• Add positive and negative keyword args to apply_cmap for requesting automatically-generated all-positive or all-negative levels (:commit:`335d58f4`). Example usage: ax.contourf(x, y, z, positive=True).
• Add rotation keyword to colorbar_wrapper for rotating colorbar tick labels, like xrotation and yrotation (:commit:`2d835f20`).
• Add tickdir and tickdirection keywords to colorbar_wrapper for controlling tick style, like xtickdir and ytickdir (:commit:`f377f090`).
• Allow specifying labels for auto-generated legends using a 'labels' key in a legend_kw keyword argument (:commit:`a11d1813`).
• Replace legends drawn in the same location by default rather than drawing two legends on top of each other (:pr:`254`).
• Use Artist labels for the default list-of-artist colorbar tick labels if values was not passed -- and if labels are non-numeric, rotate them 90 degrees for horizontal colorbars by default (:commit:`ed8e1314`). Makes the choice between "traditional" legends and "colorbar-style" legends more seamless.
• Use same default-level generation algorithm for contour plots without colormaps as for all other colormap plots (:commit:`10e0f13b`). Makes automatically-generated solid-color contours and colormap-style contours identical.
• Add suffix '_copy' to colormaps converted with to_listed and to_linear_segmented to avoid accidental overwriting (:commit:`91998e93`).
• If available, use :rcraw:`pcolormesh.snap` to repair overlap in transparent colorbar solids rather than manual-blending workaround (:commit:`c9f59e49`).
• Add xmin, xmax, ymin, and ymax keyword args to ~proplot.axes.CartesianAxes.format as alternatives to xlim and ylim (:commit:`ae0719b7`). Example usage: ax.format(xmin=0) as opposed to ax.format(xlim=(0, None)).
• Allow passing full "side" names to lonlabels and latlabels rather than abbreviations, e.g. 'left' instead of 'l' (:commit:`a5060f67`). This is more consistent with rest of package.
• Set default transform to ccrs.PlateCarree when calling matplotlib.axes.Axes.fill on CartopyAxes (:issue:`193`). This is more consistent with rest of package.

• Fix issue where e.g. ax.area(x, 0, y2, negpos=True has positive colors below x-axis and negative above x-axis (:pr:`258`).
• Fix issue where "negpos" plots ignore edgecolor because they pass color rather than facecolor to plotting commands.
• Fix issue where cannot have datetime labels on area plots (:issue:`255`).
• Fix issue where default orientation of barh vertical axis is reversed (:commit:`258`).
• Fix issue where hist with xarray.DataArray or pandas.Dataframe input causes erroneous axis labels; use labels for legend instead (:issue:`195`).
• Fix issue where axis is accidentally inverted for histogram plots (:issue:`191`).
• Fix issue where [xy]minorlocator=1 is not allowed (:issue:`219`).

• Fix issue where non-Cartesian heatmap errors rather than warns (:issue:`238`).
• Fix issue where labels=True with no contours causes error (:issue:`238`).
• Fix issue where ~proplot.colors.Cycle fails to register new names and fails to display in ~proplot.demos.show_cycles (:commit:`94ffc1dc`, :commit:`4a7a3c79`).
• Fix issue where proplot ignores set_under and set_over values when translating matplotlib colormap classes to proplot subclasses (:issue:`190`).

• Fix issue where proplot fails to detect legend entries for "outer" legends (:issue:`189`).
• Fix issue where list-of-list-style legend() handle and label input fails completely (:commit:`a298f81f`). This input style is used to specify "centered" legend rows.

• Fix issue where numeric zero cannot be applied as legend label (:commit:`02417c8c`).
• Fix issue where simple pandas.DataFrame.plot calls with legend=True fail (:pr:`254`, :issue:`198`).
• Fix unnecessary restriction where users can only draw <2 "alt" axes and clean up the alt[xy] and dual[xy] internals (:issue:`226`).
• Fix matplotlib bug where altx and alty reset the minor locator of the shared axis to AutoMinorLocator even if the axis scale is 'log' (:commit:`2f64361d`).

• Fix obscure ~proplot.axes.Axes.parametric bug where numpy.stack tries to make nested ragged arrays from parametric coords (:commit:`b16d56a8`).
• Fix issue where where SubplotSpec.get_active_rows_columns returned incorrect number of "active" rows and columns (:commit:`5cf20b84`).
• For rc lookup with context=True, use most restrictive search mode rather than least. Otherwise ax.format() calls inside context blocks can be overwritten with the default rc values in subsequent ax.format() calls (:commit:`8005fcc1`).

Internals

• Refactor massive standardize_(1d|2d) and (cmap|cycle)_changer wrappers to break things into manageable chunks (:pr:`258`, :commit:`6af22567`, :commit:`d3352720`).
• Refactor colorbar and legend methods and their massive wrappers to clean things up and expand the "queueing" feature beyond wrappers (:pr:`254`).
• Add prefix 'proplot_' to registered axes "projections" (:commit:`be7ef21e`). More clear and guards against conflicts with external packages and other mpl versions.
• Add system for processing flexible keyword arguments across different commands to internals/__init__.py. Analogous to mpl _alias processing.

Documentation

• Finally use pplt as the recommended abbreviation: import proplot as pplt.
• Major clean up of "Why ProPlot?" page and user guide pages.
• Fix incomplete cmap.from_file docstrings (:commit:`54f1bc7c`).

• Rename public/documented func make_mapping_array to private function, following lead of matplotlib's makeMappingArray (:commit:`66ae574b`).
• Rename public/documented funcs cmap_changer and cycle_changer to apply_cmap and apply_cycle (:commit:`86f7699a`).

Features

• Change autoformat from a Figure keyword argument into the :rcraw:`autoformat` rc setting (:commit:`3a7e5a7c`).
• Combine shading and lines when drawing on-the-fly legends with indicate_error shading using tuple of fill_between, plot handles, and have shadelabel and fadelabel instead create separate entries only when passed (:issue:`187`).

Bug fixes

• Fix major issue where calling legend() without any handles triggers error rather than using default handles (:issue:`188`).
• Fix issue where on-the-fly colorbar labels were ignored (:commit:`a642eeed`).
• Stop overwriting existing axis labels when autoformat=True and DataArrays or DataFrames passed to plotting command (:commit:`76c7c586`).

Bug fixes

• Fix issue where proplot import fails if cartopy is not installed (:commit:`e29d49e8`).

Deprecated

• Remove ~proplot.figure.Figure setters like set_sharex, replace with read-only properties (:commit:`7b455008`). These did not work and did not add critical functionality.

Features

• Add autoformat as ~proplot.axes.standardize_1d and ~proplot.axes.standardize_2d keyword arg, so inheriting labels can be turned on/off for individual plots (:commit:`61258280`).
• Share initial limits/scales/tickers from parent subplots when making new panels (:commit:`cf0d5d4e`).
• Permit negative "cuts" with ~proplot.colors.LinearSegmentedColormap.cut to expand the neutral zone of a diverging cmap (:commit:`94548d09`).

• Remove the geoaxes and geogrid rc settings (:pr:`168`). Gridline settings are now controlled with grid.
• Remove the lonstep and latstep settings -- we now use ~proplot.ticker.LongitudeLocator and ~proplot.ticker.LatitudeLocator to select "nice" gridline locations even when zoomed in (:pr:`168`)
• Change default rc settings closer to matplotlib, including margins and line width (:pr:`166`, :commit:`f801852b`). Many were changed for no good reason.
• Change default line style for geographic gridlines from ':' to '-' and match style from primary gridlines (:pr:`166`, :commit:`f801852b`).
• Rename add_errorbars to ~proplot.axes.indicate_error and rename various keyword args (:pr:`166`, :commit:`d8c50a8d`).
• Remove 'rgbcycle' setting (:pr:`166`, :commit:`6653b7f0`).

• Drop support for .rgba files, but optionally read 4th opacity column from .rgb and .txt files (:commit:`4fa72b0c`).
• Stop reversing the 'Spectral' colormap when ProPlot is imported (:pr:`149`, :commit:`ce4ef6a0`).
• Remove 'Blue0' SciVisColor colormap (:pr:`149`, :commit:`7cb4ce0f`). It was odd man out in the table, and not even really perceptually uniform.
• Remove custom ProPlot cycles -- these should be thought out much more carefully (:commit:`43f65d17`).
• Remove "crayola" colors and clean up the ~proplot.setup.register_colors algorithm (:pr:`149`, :commit:`8922d6de`). Crayola color names less intuitive than XKCD.
• Use 'cmap_s' instead of 'cmap_shifted' to quickly get a 180 degree-shifted colormap, similar to 'cmap_r' (:pr:`149`, :commit:`da4ccb08`).
• Rename GrayCycle colormap to MonoCycle to more accurately reflect colormap design origins (:pr:`149`, :commit:`d67e45bf`).
• Rename ~proplot.config.rc_configurator and ~proplot.ui.subplot_grid to ~proplot.config.RcConfigurator and ~proplot.ui.SubplotsContainer to match capitalized class naming convention (:pr:`149`).

The old method names remain with a deprecation warning.

Features

• No longer distinguish between "quick" settings and proplot's "added" settings (:pr:`167`, :commit:`e6dd8314`). Quick settings, added settings, and matplotlib settings can all have "children" so the distinction no longer makes sense.
• Add opacity-preserving functions ~proplot.utils.to_rgba and ~proplot.utils.to_xyza, plus ~proplot.utils.set_alpha for changing alpha channel of arbitrary color (:pr:`171`, :commit:`81c647da`).
• Add to ~proplot.colors.LinearSegmentedColormap.set_alpha the ability to create an opacity gradation, rather than just an opacity for the entire colormap (:pr:`171`, :commit:`4583736`).

• Permit drawing "outer" axes and figure legends without explicitly passing handles (:pr:`149`, :commit:`a69b48eb`). Figure legends use the handles from all axes.
• Add ~proplot.styletools.LinearSegmentedColormap.to_listed and ~proplot.styletools.PerceptuallyUniformColormap.to_linear_segmented methods for handling conversions (:pr:`149`, :commit:`e1a08930`).
• Permit merging mixed colormap types ~proplot.styletools.LinearSegmentedColormap with ~proplot.styletools.PerceptuallyUniformColormap (:commit:`972956b1`).
• Include the alpha channel when saving colormaps and cycles by default (:pr:`149`, :commit:`117e05f2`).
• Permit 8-character hex strings with alpha channels when loading colormaps and color cycles from hex files (:pr:`149`, :commit:`381a84d4`).
• Publicly support "filling" axes with colorbars using loc='fill' (:pr:`149`, :commit:`057c9895`).
• Return both figure and axes in show_ functions; this gives users access to the axes and prevents drawing them twice in notebooks (:pr:`149`, :commit:`2f600bc9`).
• Enable passing callables to ~proplot.axistools.Formatter to create a ~proplot.axistools.FuncFormatter instance.
• Support sampling ~prolot.styletools.LinearSegmentedColormap into ~proplot.styletools.ListedColormaps inside of ~proplot.styletools.Colormap rather than ~proplot.styletools.Cycle (:issue:`84`, :commit:`972956b1`).

Internals

• Include flake8 in Travis CI testing (:commit:`8743b857`).
• Enforce source code PEP8 compliance (:commit:`78da51a7`).
• Use pre-commit for all future commits (:commit:`e14f6809`).
