 * [VIM-566](https://youtrack.jetbrains.com/issue/VIM-566) Added support for `:set foldlevel` option - control fold visibility level
 
 ### Fixes:
+* [VIM-4135](https://youtrack.jetbrains.com/issue/VIM-4135) Fixed IdeaVim not loading in Rider
+* [VIM-4134](https://youtrack.jetbrains.com/issue/VIM-4134) Fixed undo in commentary - `gcc`/`gc{motion}` changes are now properly grouped as a single undo step
+* [VIM-4134](https://youtrack.jetbrains.com/issue/VIM-4134) Fixed `=` (format/auto-indent) action in split mode
+* [VIM-4134](https://youtrack.jetbrains.com/issue/VIM-4134) Fixed global marks causing errors when used inside write actions (e.g., during document modifications)
 * [VIM-4105](https://youtrack.jetbrains.com/issue/VIM-4105) Fixed `a"` `a'` `a\`` text objects to include surrounding whitespace per Vim spec
 * [VIM-4097](https://youtrack.jetbrains.com/issue/VIM-4097) Fixed `<A-n>` (NextOccurrence) with text containing backslashes - e.g., selecting `\IntegerField` now works correctly
 * [VIM-4094](https://youtrack.jetbrains.com/issue/VIM-4094) Fixed UninitializedPropertyAccessException when loading history
+* [VIM-4016](https://youtrack.jetbrains.com/issue/VIM-4016) Fixed `:edit` command when project has no source roots
 * [VIM-3948](https://youtrack.jetbrains.com/issue/VIM-3948) Improved hint generation visibility checks for better UI component detection
+* [VIM-3473](https://youtrack.jetbrains.com/issue/VIM-3473) Fixed "Reload .ideavimrc" action in remote development (split) mode - no longer causes File Cache Conflict dialogs
+* [VIM-2821](https://youtrack.jetbrains.com/issue/VIM-2821) Fixed undo grouping when repeating text insertion with `.` in remote development (split mode)
+* [VIM-1705](https://youtrack.jetbrains.com/issue/VIM-1705) Fixed window-switching commands (e.g., `<C-w>h`) during macro playback
+* Fixed `pumvisible()` function returning incorrect result (was inverted)
+* Fixed `<Esc>` not properly exiting insert mode in Rider/CLion when canceling a completion lookup
+* Fixed `<Esc>` not exiting insert mode after `<C-Space>` completion in Rider
+* Fixed `<Esc>` in search bar no longer inserts `^[` literal text when search is not found - panel is now properly closed
+* Fixed IdeaVim entering broken state when a VimScript extension plugin fails to initialize
+* Fixed compatibility issues with external plugins (e.g., IdeaVim-EasyMotion, multicursor)
+* Fixed recursive key mappings (e.g., `map b wbb`) causing an apparent infinite loop - `maxmapdepth` limit now properly terminates the entire mapping chain
+* Fixed NERDTree `gs`/`gi` preview split commands to keep focus on the tree
+* Fixed visual marks (`<` and `>`) position tracking after text deletion - `gv` now re-selects correctly
+* Fixed `IndexOutOfBoundsException` when using text objects like `a)` at end of file
 * Fixed high CPU usage while showing command line
 * Fixed comparison of String and Number in VimScript expressions
