+- Add `bingroup` to `histogram`, `histogram2d` and `histogram2dcontour` to group
+  traces to have compatible auto-bin values [#3845]
+- Add legend `itemclick` and `itemdoubleclick` attributes to set or disable
+  the legend item click and double-click behavior [#3862]
+- Add `insidetextanchor` attribute for `bar` and `waterfall` traces [#3817]
+- Add `textangele` attribute for `bar` and `waterfall` traces [#3817]
+- Add `textinfo` to `waterfall` traces [#3790]
+- Add support for side-by-side `scatter3d` `marker` and `line` colorbars [#3803]
+- Add `meta` attribute to traces to complement `layout.meta` [#3865]

+  border has been updated [#3856]
+- Draw `box` and `violin` points as legend item when other parts have opacity `0` [#3846]
+- Draw `marker.line` for bars with no-span [#3848]

+  without geographic features [#3856]

+- Fix `categoryarray` ordering for `heatmap` and `contour` traces [#3827]
+- Fix `heatmap` brick positioning for non-overlapping categories [#3827]
+- Fix `Plotly.update` calls that resulted in removal of modebar buttons [#3825]
+- Fix auto-range for one-sided `violin` with set `width` [#3842]

+- Fix `scattergl` mode ordering in/out of selections [#3810]
+- Fix `scattergl` unselected styling in/out of select/lasso dragmode [#3810]
+- Fix `automargin` edge cases where draw code can be stuck in infinite loops [#3811]
+- Fix `locationmode: 'USA-states'` on world scope under `50m` resolution [#3856]
+- Fix reset view interactions on geo subplots following `geo.scope` updates [#3856]
+- Fix `Plotly.animate`  on graphs with multiple subplot types [#3860]
