 =========================
 
 
+bpo-40128: Mostly fix completions on macOS when not using tcl/tk 8.6.11
+(as with 3.9).
+
+bpo-33962: Move the indent space setting from the Font tab to the new Windows
+tab. Patch by Mark Roseman and Terry Jan Reedy.
+
+bpo-40468: Split the settings dialog General tab into Windows and Shell/Ed
+tabs. Move help sources, which extend the Help menu, to the Extensions tab.
+Make space for new options and shorten the dialog. The latter makes the
+dialog better fit small screens.
+
+bpo-44010: Highlight the new match statement's soft keywords: match, case,
+and _. This highlighting is not perfect and will be incorrect in some rare
+cases, especially for some _s in case patterns.
+
 bpo-44026: Include interpreter's typo fix suggestions in message line
 for NameErrors and AttributeErrors.  Patch by E. Paine.
 
+bpo-41611: Avoid occasional uncaught exceptions and freezing when using
+completions on macOS.
+
 bpo-37903: Add mouse actions to the shell sidebar.  Left click and
 optional drag selects one or more lines of text, as with the
 editor line number sidebar.  Right click after selecting text lines
 displays a context menu with 'copy with prompts'.  This zips together
 prompts from the sidebar with lines from the selected text.  This option
 also appears on the context menu for the text.
 
+bpo-43981: Fix reference leaks in test_sidebar and test_squeezer.
+Patches by Terry Jan Reedy and Pablo Galindo

 bpo-37892: Change Shell input indents from tabs to spaces.  Shell input
 now 'looks right'.  Making this feasible motivated the shell sidebar.

+masquerade rules or failure displaying complex colored (non-ascii) characters.
+
 bpo-43283: Document why printing to IDLE's Shell is often slower than
 printing to a system terminal and that it can be made faster by
 pre-formatting a single string before printing.

 bpo-33987: Mostly finish using ttk widgets, mainly for editor,
 settings, and searches.  Some patches by Mark Roseman.

+parentheses inside the parentheses of a function call.
+
+bpo-38439: Add a 256x256 pixel IDLE icon to the Windows .ico file. Created by
+Andrew Clover. Remove the low-color gif variations from the .ico file.
