+
+  ToDo: See [example notebook](https://nbviewer.org/github/JetBrains/lets-plot/blob/master/docs/f-24g/interact_pan_zoom.ipynb).

+
+    See [example notebook](https://nbviewer.org/github/JetBrains/lets-plot/blob/master/docs/f-24g/superscript_exponent.ipynb).
+
+- ToDo: In `theme()`:
+  - `legend_margin, legend_spacing, legend_spacing_x, legend_spacing_y, legend_box, legend_box_just, legend_box_spacing` parameters [[#1180](https://github.com/JetBrains/lets-plot/issues/1180)].
+
+    ToDo: See [example notebook](https://nbviewer.org/github/JetBrains/lets-plot/blob/master/docs/f-24g/theme_legend_margins.ipynb).
+
+  - `legend_key, legend_key_size, legend_key_width, legend_key_height, legend_key_spacing, legend_key_spacing_x, legend_key_spacing_y` parameters  [[#1181](https://github.com/JetBrains/lets-plot/issues/1181)].

+
+- Custom `linetype` patterns [[#1198](https://github.com/JetBrains/lets-plot/issues/1198)]:
+  - a list specifying the pattern of dashes and gaps used to draw the line: `listOf(dash, gap, dash, gap, ...)`;
+    - a list with a specified offset: `listOf(offset, listOf(dash, gap, dash, gap, ...))`;
+  - a string of an even number (up to eight) of hexadecimal digits specifying the lengths in consecutive positions in the string.

+
+- `themeLight()` is now the default theme in `qqPlot()`.
+
+- [**BREAKING**] For API deprecated in v4.0 the deprecation level raised to "Error".
