2026-04-24fix(lsp): handle self-mapped methods in supports_method #39383nightlyTristan Knight1
Problem: The LSP client incorrectly checks for server capabilities when determining support for self-mapped methods (e.g., 'shutdown'), which do not have corresponding capabilities in the server's response. This leads to false negatives when checking if such methods are supported. This was handled correctly for dynamic registrations, but not for static. Methods such as 'shutdown', do not have a related server capability and should be assumed to be supported. Solution: Update the `supports_method` logic to always return true for self-mapped methods.
2026-04-24feat(tui): restore 'ttyfast' to control tty requests #38699Kyle2
Problem: When running nvim on a remote machine over SSH, if there is high ping, then bg detection may not complete in time. This results in a warning every time nvim is started. #38648 Solution: Restore 'ttyfast' option and allow it to control whether or not bg detection is performed. Because this is during startup and before any user config or commands, we use the environment variable `NVIM_NOTTYFAST` to allow disabling `ttyfast` during initialization.
2026-04-24feat(api): nvim_echo(percent=nil) means "unknown" progress #39029Peter Cardenas3
Problem: No way to signal "unknown" or "indeterminate" progress percentage. Solution: Treat percent=nil as "indeterminate" percent.
2026-04-24fix(lsp): more info in error msg, deduplicate test #39359Justin M. Keyes1
2026-04-24fix(trust): always use "/" slashes in filepaths #39355Justin M. Keyes1
Problem: We should not use "\" (backslashes) except where absolutely required. See references in https://github.com/neovim/neovim/pull/37729 Solution: There is no reason to use "\" slashes in the trust db, so don't.
2026-04-24vim-patch:9.2.0390: filetype: some Beancount files are not recognized (#39360)zeertzjq1
Problem: filetype: some Beancount files are not recognized Solution: Detect *.bean files as beancount filetype (Bruno Belanyi) closes: vim/vim#20037 https://github.com/vim/vim/commit/521eac1877355d408c8c57bc31947cc86f31f41d Co-authored-by: Bruno Belanyi <bruno@belanyi.fr>
2026-04-23feat(excmd): add :uptime command #39331Olivia Kinnear2
Problem Nvim marks its v:starttime, but there is no user-friendly way to get Nvim's uptime. Solution Add :uptime (based loosely on uptime(1)).
2026-04-23fix(lsp): handle null id in JSON-RPC responses #38340atusy1
Problem: LSP spec allows response message to have a null request-id. This may happen when for example client sends unparseable request. https://github.com/microsoft/language-server-protocol/issues/196 Solution: Guard the server response branches against id=vim.NIL (json null), and handle error responses with null id by logging a warning and dispatching on error. Problem: CI (ubuntu asan, ubuntu tsan, windows) reports `uv_loop_close() hang?` from the two new null-id response tests. The leaked handle is the server-side accepted TCP socket created inside `server:listen` callback. The tests closed only the listener but not the accepted socket, so libuv could not finish shutting down the loop and each test session took ~2s extra to exit. Solution: Hoist the accepted socket to the outer `exec_lua` scope and close it at teardown before closing the listener. The close runs synchronously inside `exec_lua`, so the loop has time to dispose the handle before the session exits. * test(lsp): close accepted socket on read-loop exit/error Match the precedent in the handler test ("handler can return false as response") and the shared `_create_tcp_server` helper in `test/functional/plugin/lsp/testutil.lua`: close the accepted socket from inside the `create_read_loop` exit/error callbacks. The teardown close added in the previous commit remains as belt-and-suspenders, so the socket is disposed whether the server goes away first or the client does.
2026-04-23fix(trust): hash unchanged empty buffers as empty files #39027Barrett Ruth1
Problem: `vim.secure.trust()` hashes an unchanged empty buffer as a newline, so trusting an empty file by buffer never works. Solution: Hash unchanged empty-buffers `''` so buffer-based trust matches the on-disk empty file.
2026-04-23fix(lsp): malformed edit if apply_text_edits() is called twice #34954geril071
Problem: Use vim.lsp.util.apply_text_edits to re-apply the same textedit causes an incorrect edit, because apply_text_edits silently modifies the parameter. Solution: - Avoid changing `text_edit._index`. - Document this fun feature. Helped-by: Riley Bruins <ribru17@hotmail.com> Helped-by: Yi Ming <ofseed@foxmail.com> Co-authored-by: Justin M. Keyes <justinkz@gmail.com>
2026-04-23fix(pack): only use tags that strictly comply with semver spec #39342Evgeni Chasnovski1
Problem: Using `version=vim.version.range(...)` in plugin specification is meant to use semver-like tags. Whether a tag is semver-like was decided by a plain `vim.version.parse` which is not strict by default. This allowed treating tags like `nvim-0.6` (which is usually reserved for the latest revision compatible with Nvim<=0.6 version) like semver tags and resulted in confusing behavior (preferring `nvim-0.6` tag over `v0.2.2`, for example). Solution: Use `vim.version.range(x, { strict = true })` to decide if the tag name is semver-like or not. This allows tags like both `v1.2.3` and `1.2.3` while being consistent in what Nvim thinks is a semver string. This is technically not a breaking change since it was documented that only tags like `v<major>.<minor>.<patch>` will be recognized as semver.
2026-04-23fix(lsp): callHierarchy/outgoingCalls ranges are relative to caller, not ↵Ashley Hauck1
callee #39336 Problem: The fromRanges field of the result of callHierarchy/outgoingCalls is documented as being relative to the caller. Using vim.lsp.buf.outgoing_calls() opened the qflist with an entry with the callee's filename, but the caller's line number. Solution: Open the qflist with the callers file (the bufnr from the request), rather than the callees (the uri from the resulting CallHierarchyItem)
2026-04-23fix(lsp): filter code_action diagnostics to the cursor #38988Barrett Ruth1
Problem: Cursor-position `vim.lsp.buf.code_action()` requests include all diagnostics on the current line, so unrelated same-line diagnostics affect the returned actions. Solution: Filter same-line diagnostics to the cursor position for cursor-position requests.
2026-04-22feat(treesitter): expand selection to sibling node #38938altermo2
Problem: Can't expand treesitter-incremental-selection to the next and previous sibling nodes. Solution: Pressing `]N` in visual mode will expand the selection to the next sibling node, and `[N` will do the same with the previous node.
2026-04-22feat(:restart): v:starttime, v:exitreason #39282Justin M. Keyes2
Problem: - The `ZR` feature makes it more obvious that we need some sort of flag so that an `ExitPre` / `QuitPre` / `VimLeave` handler can handle restarts differently than a normal exit. For example, it's common that users want `:mksession` on restart, but perhaps not on a normal exit. - Nvim has no way to report its "uptime". Solution: - Introduce `v:starttime` - Introduce `v:exitreason`
2026-04-22perf(lsp): clear table by table.clear() #39222Yi Ming3

2026-04-22fix(options): default 'titlestring' shows CWD #39233Nick Krichevsky1
Problem: In the default 'titlestring', if the containing directory is the CWD, it renders as "." Solution: Add `:p` to the titlestring.
2026-04-22fix(pack): GIT_DIR/GIT_WORK_TREE env vars may interfere #39279fleesk1
Problem: With GIT_DIR/GIT_WORK_TREE set, the LSP on the vim.pack.update() confirmation buffer does not show the correct git log on hover. Solution: Temporarily remove the git vars from the environment.
2026-04-22vim-patch:9.2.0356: Cannot apply 'scrolloff' context lines at end of filezeertzjq1
Problem: Cannot apply 'scrolloff' context lines at end of file Solution: Add the 'scrolloffpad' option to keep 'scrolloff' context even when at the end of the file (McAuley Penney). closes: vim/vim#19040 https://github.com/vim/vim/commit/a414630393f81c9a5b8fa4d0fcc1287155f67751 Co-authored-by: McAuley Penney <jacobmpenney@gmail.com>
2026-04-22fix(:restart): avoid ERR/WRN logging on Windows with --listen (#39287)zeertzjq1
Problem: :restart leads to ERR/WRN logging on Windows with --listen. Solution: Add a log_level flag to vim._with() and use it to suppress logging from serverstart()/serverstop() during restart.
2026-04-21fix(:restart): reuse --listen addr on Windows #38539Sanzhar Kuandyk1
Problem: On Windows, :restart cannot immediately reuse the canonical --listen address because named pipe release is asynchronous. Solution: Start the new Nvim server on a temporary address; in the new Nvim, retry serverstart() with the original ("canonical") address until it succeeds.
2026-04-21feat(normal): normal-mode ZR does :restartJustin M. Keyes1
Make it a normal-mode command instead of a default mapping.
2026-04-21feat(defaults): map ZR to restartMike J. McGuirk1
Problem: No default mapping for :restart. Solution: Map to ZR in defaults. Closes: https://github.com/neovim/neovim/issues/38942
2026-04-21vim-patch:9.2.0371: filetype: ghostty config files are not recognized (#39267)zeertzjq1
Problem: filetype: ghostty config files are not recognized Solution: Detect ghostty configuration files as ghostty filetype, include a simple ghostty filetype plugin (Bez Hermoso) closes: vim/vim#20002 https://github.com/vim/vim/commit/b30803b231beea13e2efa42fefc04be71a4e9bb5 Co-authored-by: Bez Hermoso <bezalelhermoso@gmail.com> Co-authored-by: Christian Brabandt <cb@256bit.org>
2026-04-20fix(ui2): don't dismiss expanded messages for non-typed key #39247luukvbaal2
Problem: Invalid check for non-typed key to dismiss expanded cmdline. Unable to delay the timer that removes a message from the msg window. Solution: Check for empty string instead of nil to determine whether a key is typed. Restart the timer if it expires while the user is in the msg window. Allow entering the msg window with a mouse click.
2026-04-20fix(ui2): ensure msg window is visible after closing tabLuuk van Baal1
Problem: After closing a tabpage while the msg window is showing a message, it is hidden while the msg window still contains a message. Solution: Unhide the msg window after entering a tabpage and it still contains a message. Co-authored-by: Linykq <yukunlin590@gmail.com>

2026-04-20fix(api): expose fg_indexed/bg_indexed in nvim_get_hl #39210glepnir2
Problem: fg_indexed/bg_indexed were dropped from nvim_get_hl output due to a wrong short_keys guard. HL_FG_INDEXED also wasn't cleared in hl_blend_attrs, and HLATTRS_DICT_SIZE was too small. Solution: Remove the short_keys guard, clear HL_FG_INDEXED in hl_blend_attrs, bump HLATTRS_DICT_SIZE to 24, and clarify docs that these flags mean rgb is an approximation of the cterm palette index.

2026-04-19feat(options): add 'winpinned' to pin a window #39157luukvbaal2
Problem: - Unable to "pin" a window to prevent closing without specifically being targeted. - :fclose closes hidden windows (even before visible windows). Solution: - Add 'winpinned' window-local option. When set, window is skipped by :fclose and :only. Pin the ui2 cmdline window (which should always be visible), so that it is not closed by :only/fclose. - Skip over hidden (and pinned) windows with :fclose.

2026-04-19feat(excmd): add EXX error codes for :lsp, :log #39135Olivia Kinnear1
Also remove the `--add-comments` flag from `xgettext` because it dumped a bunch of comments from Lua files into the `.pot` files.
2026-04-18fix(lsp): stale codelens after external file change (#39203)Jaehwang Jung1
Problem: Codelens virtual lines remain on stale rows after an external file change and buffer reload. Solution: Clear codelens extmarks and cached row/version state in `on_reload` before requesting fresh code lenses.
2026-04-18fix(lsp): show CompletionItem.detail in info popup #38904glepnir1
Problem: completionItem/resolve response's `detail` field is silently dropped. Only `documentation` is shown in the popup. Solution: Prepend `detail` as a fenced code block before `documentation` in the info popup, skipping if documentation already contains it.
2026-04-18docs: misc #39045Justin M. Keyes9
2026-04-18fix(lsp): skip codelens refresh redraw for deleted buffer #39193Jaehwang Jung1
Problem: After on_refresh() sends a textDocument/codeLens request, the buffer may be deleted before the response arrives. The response callback then tries to redraw that deleted buffer and raises Invalid buffer id error. Solution: Check buffer validity before redrawing. AI-assisted: Codex Co-authored-by: Yi Ming <ofseed@foxmail.com>
2026-04-18docs(events): Lua types for autocmd event-data #38518Aditya Malik2
Problem: No LuaLS types for event-data fields (ev.data). Types are only documented ad hoc in scattered locations. Solution: Add runtime/lua/vim/_meta/events.lua defining vim.event.<name>.data classes for events that provide ev.data. Reference the types from each event's help in autocmd.txt, lsp.txt, and pack.txt.
2026-04-18fix(lua): make `vim._with()` work with `buf=0` and `win=0` context #39151Evgeni Chasnovski1
Problem: Using `buf=0`/`win=0` context in `vim._with` should be equivalent to using explicit buffer/window identifier respectively. Solution: Explicitly adjust context in case of `buf=0` or `win=0`.
2026-04-18refactor(vimfn): full-Lua impl of vim.fn.environ()Justin M. Keyes1
2026-04-18feat(vimfn): use Lua for more excmds/vimfnsJustin M. Keyes4
Problem: Too much boilerplate needed to use Lua to impl an excmd or f_xx function. Solution: - Add `nlua_call_vimfn` which takes the args typval, executes Lua, and returns a typval. - refactor(excmd): lua impl for :log, :lsp
2026-04-18fix(vim.filetype): match() fails if g:ft_ignore_pat is not defined #39158Evgeni Chasnovski1
Problem: Calling `vim.filetype.match({ filename = '...', buf = ... })` during startup results in an error due to not yet defined `g:ft_ignore_pat`. Solution: Add a guard to check `g:ft_ignore_pat` related properties only if the variable is defined. This also allows to simplify other tests which did not depend on `g:ft_ignore_pat` but required it explicitly set to work.
2026-04-17fix(lsp): limit number of created highlight groups (#39133)Evgeni Chasnovski1
* fix(api): allow silencing "Too many highlight groups" error Problem: Using Lua's `vim.api.nvim_set_hl(0, 'New', {...})` can fail if there are too many existing highlight groups. However, this error can not be silenced with `pcall`. Solution: Make it possible to silence in `nvim_set_hl` and `nvim_get_hl_id_by_name`. * fix(lsp): limit number of groups created by `document_color()` Problem: A file can contain many string colors that would be highlighted by an LSP server. If this number crosses 19999 (maximum number of allowed highlight groups), there are general issues with creating other highlight groups, which can break functionality outside of `vim.lsp.document_color`. Solution: Limit number of highlight groups that are created by `vim.lsp.document_color` to 10000 (half of allowed maximum). This is not a 100% solution (since there can exist more than 10000 other highlight groups), but explicitly checking number of groups is slow and 10000 should (hopefully) be enough for most use cases.
2026-04-17perf(vim.fn): call Lua-implemented vim.fn.xx() directly #39166Justin M. Keyes2
Problem: - Builtin "Vimscript" functions (f_xx) are mostly implemented in C. Partly that's because there is some boilerplate required to call out to Lua. - Calls to `vim.fn.foo()` always marshall over the Lua <=> Vimscript ("typval") bridge, even if `fn.foo()` is implemented entirely in Lua: ``` Lua => typval => Object => Lua => Object => typval => Lua. ``` Solution: Functions declared in eval.lua with `func_lua` are implemented in entirely in Lua (`_core/vimfn.lua`). - `gen_eval.lua` wires `func_lua` entries to `lua_wrapper`, which handles the typval conversion for Vimscript callers (slow path). - `nlua_call()` detects `func_lua` functions and calls the Lua implementation directly. This eliminates all conversion overhead for Lua callers (fast path). - Validate at build-time that `func`, `func_float`, and `func_lua` are mutually exclusive. - Migrate `hostname()` as a toy example, to show the idea.
2026-04-17vim-patch:8.2.2440: documentation based on patches is outdated (#39144)zeertzjq1
Problem: Documentation based on patches is outdated. Solution: Add changes to documentation in a patch. https://github.com/vim/vim/commit/853886722c051ecaef6d818ce32a822e4f43dc2b Trailing space was removed in later patches. Also fix a few more misplaced error numbers from #8155. Co-authored-by: Bram Moolenaar <Bram@vim.org>
2026-04-16fix(ui2): dialog paging is inconsistent #39128luukvbaal1
Problem: - Paging keys in the dialog window consume input when the user may not expect it. The dismissable title hint intended to mitigate that results in having to press Escape twice to abandon the prompt. - Mimicked "msgsep" float border is taking up unnecessary space when window takes up the entire screen. Solution: - Use (conventional, albeit less convenient) keys intended for scrolling to page the dialog window: <(Mousewheel/Page)Up/Down>, <Home/End>. - Only set the float top border when separation is actually necessary, i.e. window does not reach the first row.
2026-04-16refactor(lsp): provide a default list handler example #39005Yi Ming1
Problem: Difficult for us to provide default handlers for functions like `vim.lsp.buf.definition`. When users wanted to fine-tune the default behavior, they don't know how. Solution: - Document an example providing `on_list` boilerplate to make it easier for users to modify and override. - Also, considering that the parameters of the previous `on_list`(`vim.lsp.ListOpts.OnList`) are compatible with the parameters of `setqflist`, remove that custom type in favor of passing `vim.fn.setqflist.what`.
