 ## [To Be Released]
 
 ### Features:
-* [VIM-1693](https://youtrack.jetbrains.com/issue/VIM-1693) Added `:autocmd` command - run Ex commands on editor events such as `BufRead`, `BufWrite`, `BufEnter`, `BufLeave`, `InsertEnter`, `InsertLeave`, `WinEnter`, `WinLeave`, `FocusGained`, `FocusLost`, and `FileType`; supports `augroup` and file pattern matching (e.g., `autocmd BufWritePre *.py echo "saving python"`)
-* [VIM-268](https://youtrack.jetbrains.com/issue/VIM-268) Added file name completion in ex commands - press `<Tab>`/`<S-Tab>` to cycle through file matches in `:edit`, `:split`, `:vsplit`, `:write`, `:read`, `:source`, and `:find` commands; use arrow keys to navigate the completion panel
 * New VimScript functions: `add()`, `call()`, `extend()`, `extendnew()`, `filter()`, `flatten()`, `flattennew()`, `foreach()`, `has_key()`, `indexof()`, `insert()`, `items()`, `keys()`, `map()`, `mapnew()`, `reduce()`, `remove()`, `slice()`, `sort()`, `uniq()`, `values()`
 * [VIM-1595](https://youtrack.jetbrains.com/issue/VIM-1595) Added support for `:read` command - insert file content below current line (e.g., `:read file.txt`, `0read file.txt`)
 * [VIM-1595](https://youtrack.jetbrains.com/issue/VIM-1595) Added support for `:read!` command - insert shell command output below current line (e.g., `:read! echo "hello"`)

 * [VIM-566](https://youtrack.jetbrains.com/issue/VIM-566) Added support for `zf` command - create fold from selection or motion
 * [VIM-566](https://youtrack.jetbrains.com/issue/VIM-566) Added support for `:set foldlevel` option - control fold visibility level
-* [VIM-1158](https://youtrack.jetbrains.com/issue/VIM-1158) Added `gw` command - reformat code like `gq` but preserving the cursor position
 
 ### Fixes:
-* [VIM-4197](https://youtrack.jetbrains.com/issue/VIM-4197) Fixed Vim features (e.g., `f`, `w`, text objects) not working in Java files decompiled from Kotlin class files
-* [VIM-4112](https://youtrack.jetbrains.com/issue/VIM-4112) Fixed undo after block-visual edit (`<C-V>...x`, `<C-V>...c`, `<C-V>...I`) leaving stray carets in normal mode
-* [VIM-4176](https://youtrack.jetbrains.com/issue/VIM-4176) Fixed race condition in single-line output panel that could cause `*` search wrapping to behave unreliably
-* [VIM-4175](https://youtrack.jetbrains.com/issue/VIM-4175) Fixed search "not found" showing previous "Hit ENTER" text alongside the error - panel is now cleared before displaying errors like "E486: Pattern not found"
-* [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-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-4195](https://youtrack.jetbrains.com/issue/VIM-4195) Fixed settings not being saved in remote development (split) mode
-* [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 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
-* Fixed `\/`, `\?`, and `\&` in Ex command ranges now correctly report E35/E33 errors when no previous search or substitute pattern exists, instead of crashing
-* [VIM-4172](https://youtrack.jetbrains.com/issue/VIM-4172) IdeaVim is now disabled in Python Console to prevent key interference

-* Fixed NERDTree navigation (`j`/`k`/`G`/`gg`/`p`/`<C-J>`/`<C-K>`) poor performance in split mode - navigation now uses Swing actions directly instead of going through backend RPC
-* [VIM-4180](https://youtrack.jetbrains.com/issue/VIM-4180) Fixed ReplaceWithRegister plugin's default `gr`/`grr` mappings overriding user-defined key mappings
-* Fixed `IndexOutOfBoundsException` when using `:command` with `-nargs` option but without a command name
-* Fixed spurious beep when pressing `<Esc>` to cancel register selection in normal mode (after pressing `"`)
-* [VIM-4202](https://youtrack.jetbrains.com/issue/VIM-4202) Fixed `<S-Tab>` being intercepted by IdeaVim - users can now remap `<S-Tab>` to other IntelliJ actions

-Autocommands
-============
-
-IdeaVim supports Vim's `:autocmd` for running commands on editor events.
-Handlers are registered from `~/.ideavimrc` or interactively in Command-line mode.
-Every effort is made to match Vim's behaviour, but some differences are inevitable
-because the IDE's event model doesn't map 1:1 onto Vim's.
-
-Syntax
-------
-
-```
-autocmd [group] {event}[,{event}...] {pattern} {command}
-autocmd!
-autocmd! {group}
-```
-
-- `{event}` — one or more comma-separated event names (see below).
-- `{pattern}` — file pattern (see "Patterns" below). For `FileType`, the pattern matches the filetype name, not the file
-  path.
-- `{command}` — any Ex command or Vimscript expression.
-- `autocmd!` — clears all registered handlers, or all handlers in the given augroup.
-
-```vim
-augroup my_group
-  autocmd!
-  autocmd BufWritePre *.py echo "saving python"
-augroup END
-```
-
-Patterns
---------
-
-Autocmd file patterns support the following glob syntax:
-
-| Pattern     | Matches                                  |
-|-------------|------------------------------------------|
-| `*`         | Any characters except path separators    |
-| `**`        | Any characters including path separators |
-| `?`         | Any single non-separator character       |
-| `[abc]`     | Any character in the set                 |
-| `{foo,bar}` | Either `foo` or `bar`                    |
-
-If the pattern contains `/` or `\`, it matches against the full path;
-otherwise it matches against the filename only.
-
-`FileType` is special: its pattern matches against the filetype name
-(e.g. `python`, `java`) rather than the file path.
-
-Supported events
-----------------
-
-### Insert mode
-
-| Event         | Fires when           |
-|---------------|----------------------|
-| `InsertEnter` | Entering Insert mode |
-| `InsertLeave` | Leaving Insert mode  |
-
-### Buffers
-
-| Event          | Fires when                                                        |
-|----------------|-------------------------------------------------------------------|
-| `BufEnter`     | A buffer becomes active (every switch)                            |
-| `BufLeave`     | A buffer stops being active                                       |
-| `BufRead`      | A file is loaded into a buffer for the first time                 |
-| `BufReadPost`  | Alias of `BufRead` (same event, two names)                        |
-| `BufNewFile`   | Editing a file that was just created (fires instead of `BufRead`) |
-| `BufWrite`     | Alias of `BufWritePre`                                            |
-| `BufWritePre`  | Before the buffer is written to disk                              |
-| `BufWritePost` | After the buffer has been written to disk                         |

-### Event order
-
-When opening a file for the first time:
-
-```
-BufRead/BufReadPost → FileType → BufEnter
-```
-
-When opening a just-created file:
-
-```
-BufNewFile → FileType → BufEnter
-```
-
-When switching buffers:
-
-```
-BufLeave → WinLeave → WinEnter → BufEnter
-```
-
-When saving:
-
-```
-BufWrite/BufWritePre → (write) → BufWritePost
-```
-
-Differences from Vim
---------------------
-
-**`FileType` names.** IdeaVim maps IntelliJ's file type name to a Vim-style
-filetype. For most languages the lowercased IJ name matches Vim's filetype
-(`Python`→`python`, `JAVA`→`java`). A small override table handles cases where
-Vim's convention differs: `PLAIN_TEXT`→`text`, `C++`→`cpp`, `C#`→`cs`,
-`Shell Script`→`sh`, `ObjectiveC`→`objc`, `JavaScript`→`javascript`,
-`TypeScript`→`typescript`, `Vue.js`→`vue`, `CMakeLists.txt`→`cmake`,
-`Handlebars/Mustache`→`handlebars`.
-
-**`BufNewFile` detection.** IdeaVim tracks files created during the session
-via the VFS. When such a file is opened in an editor, `BufNewFile` fires
-instead of `BufRead`. Files created by VCS pulls, build tools, or external
-processes that you later open in an editor will also be treated as new files.
-
-**`BufWritePre` / `BufWritePost` frequency.** IntelliJ auto-saves on focus
-loss, tab switch, build, and other events. These autocmds fire more often
-than Vim's `:w`, so handlers should be idempotent.
