BREAKING CHANGES IN HEAD OR EXPERIMENTAL                    *news-breaking-dev*

              ====== Remove this section before release. ======

The following changes to UNRELEASED features were made during the development
cycle (Nvim HEAD, the "master" branch).

EVENTS

• todo

EXPERIMENTS

• todo

LSP

• todo

LUA

• vim.pos, vim.range always require the `buf` parameter.
• range.cursor() and range.to_cursor() are removed.
  Use range.mark() and range.to_mark() instead.
• pos.to_cursor() returns a (`row,` `col)` tuple
  instead of returning them as separate values.
• Renamed current_level param of vim.log.new().
• `vim.opt.{option}:get()` has improved structure for dict-like options.
  Some shapes changed:
  - "key:value" list options (e.g. 'diffopt', 'mousescroll') return a map
    `{ key = value }` instead of an array of `"key:value"` strings.
  - The `,,` literal-comma convention (e.g. 'isfname') is not reconstructed in
    the structured view; the raw string value is unchanged.

DIAGNOSTICS

• todo

OPTIONS

• When |ui2| is enabled, since the ruler is no longer a left-aligned box of
  fixed width, there is no longer an inconsistent special handling of item
  groups in 'rulerformat' to configure that fixed width. An old-style left-
  aligned fixed-width ruler can now be achieved by using item groups exactly
  as they are documented, e.g. `%-20.20(...%)`.

TREESITTER

• todo

UI

• Healthchecks for |vim.ui.img| were moved to `:checkhealth vim.health`.
• |ui2| messages pager no longer uses <CR> by default; use |g<| or set
  'messagesopt' "pager", e.g. `:set messagesopt+=pager:<CR>`.
• |ui2| `cfg.pager_char` and `cfg.msg.msg.timeout` were replaced by the
  'messagesopt' items "pager" and "timeout".

BREAKING CHANGES                                                *news-breaking*

These changes may require adaptations in your config or plugins.

API

• API results containing a Lua function reference (e.g. a "callback" reported
  by |nvim_get_keymap()| or |nvim_get_autocmds()|, or a "callback" option
  value) are serialized over RPC as a human-readable `"<Lua …>"` hint string,
  instead of nil.
• |nvim_create_autocmd()|, |nvim_exec_autocmds()| and |nvim_clear_autocmds()|
  no longer treat an empty non-nil pattern as nil.
• |nvim_clear_autocmds()| no longer treats an empty array event as nil.
• |vim.o|, |vim.opt|, and |nvim_set_option_value()| expand `~` and environment
  variables (|expand-env|).

DIAGNOSTICS

• `vim.diagnostic.Opts.Status.format` no longer accepts the table mapping
  from severity to text. Use `vim.diagnostic.Opts.Signs.text` instead.
• `current_line` property of |vim.diagnostic.Opts.VirtualLines| and
  |vim.diagnostic.Opts.VirtualText| is now applied on |CursorHold| event.
  Make sure your 'updatetime' is reasonable.

EDITOR

• Interactive |Ex-mode| (|:exmode|, `nvim -e`) is a persistent |cmdwin|. This is much
  more flexible and makes "Ex mode" more useful as a kind of "cmdline REPL",
  with the tradeoff of dropping some POSIX Ex-mode quirks.
  • |mode()| returns "n" or "i"; "cv" indicates |-es| (script mode) only.
  • Ex mode is entered with "1q:" or |:exmode|, not "gQ".
  • ":global/pat/visual" no longer switches to Normal mode per matching line.
• Non-interactive Ex-mode (|-es|, "script mode") executes stdin as Ex commands
  directly. It is a "script host", not "POSIX Ex mode".
  • Output ends with a final newline.
  • |:visual| is |:edit|: it does not switch to reading stdin as Normal-mode
    commands, and ":global/pat/visual" does not enter Normal mode per
    matching line.
  • Commands that wait for typed input (|input()|, |getchar()|, …) stop Nvim
    at end-of-input instead of consuming the next stdin line.
  • An empty line is a no-op instead of advancing the cursor (or failing
    with |E501| at end-of-file).
• On Windows, the |trust| db now stores paths with "/" slashes. This means the
  trust store will be reset (one time).
• `stdpath("log")` moved to `stdpath("state")/logs`.
• An operator on a target that creates a Visual selection ("cgn") does not
  change |'<| |'>|. |gv|
• |cmdwin| (|q:|, |q/|, |q?|, |c_CTRL-F|):
  • Only supports one "cmdline level", not "infinite recursion".
  • Expr-register (|i_CTRL-R_=|, |c_CTRL-R_=|) no longer supports opening
    cmdwin via |c_CTRL-F|.
• Behavior of |:restart| changed. Use "!" (|:restart!|) to get the old behavior.
  • |ZR| now performs |:restart|. Add a count to change the behavior.
• |ins-repeat| replays the full Insert session, including cursor-moves.
  Undo and |quote.| still restart at each cursor-move. Use |i_CTRL-O| to get
  the old behavior: >vim
    inoremap <Left>  <C-o><Left>
    inoremap <Right> <C-o><Right>
• |visual-repeat| is "semantic" instead of "fixed-size". See
  |visual-fixed-size| if you prefer Vim's "fixed-size" Visual-repeat.
• |:diffget|, |:diffput| (|do|, |dp|) can be |.| repeated.
• |Q| adds a |multicursor| instead of replaying the last recorded register.
  To get the old behavior: >lua
    vim.keymap.set('n', 'Q', function()
      local reg = vim.fn.reg_recorded()
      return reg == '' and '' or ('@' .. reg)
    end, { expr = true })
<

EVENTS

• |vim.on_key()| callbacks are not invoked for keys consumed by |getchar()|.
• |BufModifiedSet| has been removed. Use the |OptionSet| event with pattern
  "modified" instead.
• |ui-messages| `msg_show.bufwrite` and `msg_show.completion` messages are now
  `msg_show.progress` events.

LSP

• `vim.lsp.ClientConfig.cmd` given as a string array now uses
  `vim.lsp.ClientConfig.root_dir` as its default process working directory.
• `client.attached_buffers[buf]` now stores `languageId` string (was boolean).

LUA

• "standalone" Lua interpreter mode `nvim -ll` was removed. Use |-l| script
  mode instead.
• |vim.opt| no longer supports chaining multiple infix operators (e.g.
  `vim.opt.wildignore + '*.o' + '*.obj'`). Instead, use tables:
  `vim.opt.wildignore + {'*.o', '*.obj'}`

OPTIONS

• The 'statusline' `%=` item is no longer ignored in item groups. It applies
  to the containing item group and its `minwid`.
  An `%<` item inside an item group now only applies to the containing group
  and its `maxwid`. Therefore, multiple `%<` can now be effective.
  The default truncation of item groups is now at the first contained item.
  To restore the previous truncation from the left, add a `%<` to the start.
  The same applies to 'rulerformat', 'statuscolumn', 'tabline', 'winbar',
  'titlestring', and 'iconstring'.
• 'rulerformat' can no longer be set empty, the new default expression will be
  restored instead.

PLUGINS

• todo

TREESITTER

• todo

UI

• The bottom right cell of the screen is no longer left empty when the ruler
  is shown. This was originally intended to prevent unwanted scrolling on
  quirky terminals.

VIMSCRIPT

• Removed: ctxget(), ctxpop(), ctxpush(), ctxset(), ctxsize(). Use
  |nvim_get_context()| and |nvim_load_context()| instead.

==============================================================================
NEW FEATURES                                                    *news-features*

The following new features were added.

API

• |nvim_win_resize()| resizes a window with a specified anchor edge.
  |nvim_win_set_height()| and |nvim_win_set_width()| are now deprecated.
• |api-contract| treats `opts` and any parameters thereafter, as optional
  (equivalent to passing an empty dict). Clients may omit such optional
  parameters.
  • The Lua |vim.api| bridge is also a "client" and thus may omit `opts` and
    any following parameters: >lua
    -- Before:
    vim.print(vim.api.nvim_get_mark('A', {}))
    -- After:
    vim.print(vim.api.nvim_get_mark('A'))
• |nvim_buf_call()| and |nvim_win_call()| now preserve multiple return values.
• |nvim_del_keymap()|, |nvim_buf_del_keymap()| and |vim.keymap.del()| can
  match only {lhs}, not {rhs}, with `opts.lhs=true`.
• |nvim_set_hl()| supports "font" key.
• |nvim_open_win()| `zindex` controls whether the UI will use a dimmed cursor
  shape when an unfocused float is on top of the cursor.
• |nvim_echo()| distinguishes zero percent from omitted percent for Progress
  events.
• |nvim_create_user_command()| accepts `desc` for Vimscript commands.
• Support for tabpage-local options ('cmdheight'):
  • |gettabvar()|
  • |gettabwinvar()|
  • |nvim_get_option_info2()|
  • |nvim_get_option_value()|
  • |nvim_set_option_value()|
• |nvim_buf_set_extmark()| `virt_lines_overflow` accepts "wrap" to enable
  wrapping onto extra rows and "auto" which enables horizontal scrolling when
  'nowrap' is set and wrapping when 'wrap' is set.
• |nvim_buf_set_extmark()|  `virt_lines` can extend the last `hl` in each `virt_line`
  till the end of the line.
• |nvim_set_option_value()| accepts a new `operation` field to modify the
  existing option value.
• |nvim_set_option_value()| returns the new option value.
• |nvim_create_autocmd()| is now |api-fast|, so it can be called from a fast
  event context (e.g. |vim.uv| callbacks).
• |nvim_create_autocmd()| callback |event-args| provide `win`.
• |nvim_chan_set()| sets channel properties. With `detach=false`, any RPC
  channel can enable Nvim "self-exit on channel-close" behavior.

BUILD

• Building using "zig build" requires zig 0.16.x.
• zig build: "-Dcross" option was removed. Often cross-compilation is now
  detected, so e.g. from a linux host: >
   zig build -Dtarget=aarch64-macos
<  will automatically compile a host Lua for use during build.
• zig build: The new "-Dhost={target_string}" option can be used to override
  the used host. Use "-Dhost=native" to force cross-compiling or "-Dhost="
  (empty string) to assume that target binaries can run on the host during the
  build process (e.g. if target is x86 on a x86_64 system, or if emulation set
  up with binfmt or similar).
• zig build: Nvim can now be built to produce a WebAssembly binary via
  "-Dtarget=wasm32-emscripten", which can run inside a web browser. A basic
  browser-based demo for running it is also included. Still very
  experimental.

DEFAULTS

• 'rulerformat' default is exposed as a statusline expression (previously it
  was implemented as an internal C routine).
• 'termpastefilter' no longer removes TAB chars ("HT") when pasting into
  |:terminal|.

DIAGNOSTICS

• |vim.diagnostic.status()| uses the severity names defined by the `signs`
  field of |vim.diagnostic.config()|, if any.
• `virtual_lines.overflow` in |vim.diagnostic.config()| controls
  how virtual lines wider than the window are displayed.

EDITOR

• Multiple cursors (|multicursor|): edit in many places at once.
  • Toggle cursors with |Q|, |<C-LeftMouse>|, or via API (the
    "nvim.multicursor" extmarks namespace).
  • Toggle "follow mode" with |q=|.
  • Clear cursors with |CTRL-L|, restore them with |gQ|.
  • |zq| places a cursor at all targets of a motion. E.g. "zqgn" places at
    every match (and "gv" selects the matches), "Vzqw" places at every
    Visual-selected word.
• |:bcd| sets a buffer-local directory. |getcwd()| and |haslocaldir()| take
  `bufnr` as a third parameter.
• |:lcd!| |:tcd!| |:bcd!| unsets the directory of that scope.
• |:command-completion-customlist| can return a list of dictionaries with
  kind/menu/info/abbr for the popup menu.
• |cmdwin| (|q:|, |q/|, |q?|, |c_CTRL-F|) is implemented as a "normal"
  buffer+window instead of a nested-state modal loop:
  • You can create/navigate windows/tabpages while cmdwin is active. Chaos!
  • 'inccommand' works in cmdwin!
  • API calls (e.g. |nvim_buf_delete()|) that previously failed with
    "E11: Invalid in command-line window" while cmdwin was open, now work
    normally. Async plugins no longer need special |CmdwinLeave| workarounds.
  • The |cmdwin-char| is shown via 'statuscolumn'.
• |gf| and |<cfile>| support `file://…` URIs.
• |:help| files can contain tables, see |help-table|. Example:
  |supported-platforms| (https://neovim.io/doc/user/support/#supported-platforms).
• |:help| documentation is available as PDF via:
  https://neovim.io/doc/user/nvim-help.pdf
• |:log| opens log files.
• |:marks| can list |extmarks| for a given |namespace|.
• |:marks| gained tab-completion.
• |:restart| saves/restores the current session (window layout, buffers, …).
  • |:restart!| (with a bang "!") does not save/restore the session.
• |ZR| restarts Nvim (|:restart|).
• |:detach| with range "%" detaches all UIs except the current one.
• |:detach!| (with bang "!") marks the current UI as detachable: Nvim will
  continue running if the UI disconnects unexpectedly (e.g. if you
  accidentally close your terminal, ssh connection lost, etc.).
  Use |:connect| to reattach.
• |:uptime| displays uptime.
• |:packupdate| and |:packdel| for managing |vim.pack|.
• 'scrollback' is now also valid in |prompt-buffer| buffers to limit the
  number of history lines kept above the prompt.
• |v_al| and |v_il| text objects select the whole buffer and the current line
  without leading or trailing white space.
• 'autoread' uses file system watchers to detect external changes in
  real-time, instead of only on |FocusGained| or |:checktime|.
• During |complete()|-triggered completion, CTRL-N and CTRL-P are now subject
  to insert-mode mappings.
• |undo| restores the cursor to its original position ("diw", "atest<Esc>",
  "d^", …), instead of jumping to the start of the changed text.
• |undo| no longer restores the old (wrong) position of a mark that you moved
  (|m|, |:mark|) later. The mark shifts with the text it was moved to, the
  same as a mark the change never touched.
• Multibyte characters, translated by 'langmap', now invoke correct
  mappings.
  Example: >vim
    set langmap=õ]
<    Typing õõ in |Normal-mode| now invokes a mapping bound to ]].
• New |complete-items| field "commit_chars": characters that accept the
  selected completion item when typed.

EVENTS

• |:delmarks| now triggers the |MarkSet| autocommand with line==col==0, same
  as |nvim_buf_del_mark()|
• |ChanClose| is triggered after a channel is closed, before it is removed.
• |CmdAtom| fires after each atomic user action (motion, mapping, operator,
  insert session, visual, Ex command, …).
• |SessionWritePre| event emits just before |:mksession|.
• |TextPutPre| and |TextPutPost| are triggered before/after putting text.
• |TabMoved| is triggered when tabs are reordered.
• |DirReadPost| is triggered after each |dir| listing is rendered, so it can
  be sorted or filtered. See |dir-render|.

HIGHLIGHTS

• `Dimmed` for text that should be de-emphasized.
• |vim.hl.hl_op()| highlights text regions for |TextYankPost| and
  |TextPutPost| events. It replaces the now deprecated `vim.hl.on_yank()`.

LSP

• LSP capabilities:
  • Completion supports `CompletionItem.preselect` if 'completeopt' has
    "preselect". https://microsoft.github.io/language-server-protocol/specification/#completionClientCapabilities
  • `textDocument/foldingRange` |vim.lsp.foldtext()| highlights collapsed text.
    https://microsoft.github.io/language-server-protocol/specification/#textDocument_foldingRange
  • Completion supports `CompletionList.applyKind`: a server can ask for
    `commitCharacters` and `data` from `itemDefaults` to be merged with the
    item's own values instead of replacing them.
    https://microsoft.github.io/language-server-protocol/specification/#completionItemApplyKinds
  • Completion supports a `completionProvider` registered with
    `client/registerCapability` instead of declared at `initialize`. Nvim does
    not advertise `completion.dynamicRegistration` by default; set it in
    |vim.lsp.Config| `capabilities` to opt in.
    https://microsoft.github.io/language-server-protocol/specification/#client_registerCapability
• `:checkhealth vim.lsp` highlights the "current buffer".
• |vim.lsp.buf.declaration()|, |vim.lsp.buf.definition()|,
  |vim.lsp.buf.type_definition()|, and |vim.lsp.buf.implementation()|
  now follows 'switchbuf'.
• |vim.lsp.buf.declaration()|, |vim.lsp.buf.definition()|,
  |vim.lsp.buf.type_definition()|, and |vim.lsp.buf.implementation()|
  now supports passing arbitrary positions.
• Support for nested snippets.
• |lsp-completion| supports `commitCharacters`: typing a commit character
  while a completion item is selected accepts the item as with
  |complete_CTRL-Y|, then inserts the character. Previously
  `commitCharacters` had no effect.
• The `reuse_client` predicate now passes the target buffer. See |vim.lsp.Config| and
  |vim.lsp.start()|
• |vim.lsp.formatexpr()| now falls back to `textDocument/formatting` if the whole
  buffer is being formatted and the language server doesn't support
  `textDocument/rangeFormatting`.
• |vim.lsp.buf.format()| respects an explicit `timeout_ms` with `async=true`.
  The timeout applies per client. Async requests have no timeout when the
  option is omitted.
• Support for `workspace/foldingRange/refresh`:
  https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#workspace_foldingRange_refresh
• |vim.lsp.completion.get()| accepts a `client_id` to request from only the
  given clients.

LUA

• |lua-async|: `vim.async` provides structured concurrency primitives for Lua
  code, including task handles, await helpers, cooperative cancellation,
  completion-order iteration, and semaphores.
• |vim.inspect_pos()| and |vim.show_pos()| support byte ranges with `end_row`
  and `end_col`. |:Inspect| accepts line ranges, including Visual selections.
• |vim.ui.img| can display images. Use `:checkhealth vim.health` to confirm
  your terminal supports it.
• |vim.net.request()| can specify custom headers by passing `opts.headers`.
• |vim.net.request()| can now accept  `method` param overload for multiple HTTP methods.
• |writefile()| treats Lua and RPC strings as |Blob|, so it can be used to
  write binary data.
• |vim.fs.abspath()| gained `cwd` and `plain` parameters.
• |vim.fs.dir()| with `opts.err=true`, reports errors. An inaccessible root
  dir yields a single (name, nil, err) item.
• |vim.fs.dir()| gained a `plain` parameter.
• |vim.fs.find()| returns a list of errors as its second return value.
• |vim.fs.mkdir()| creates directories, including parent directories with
  `opts.parents=true`.
• |vim.fs.slug()| generates a filesystem-safe file name from an arbitrary
  identity string, with an optional length bound.
• |vim.filetype.inspect()| returns a copy of the internal tables used for
  filetype detection.
• Added `__eq` metamethod to |vim.VersionRange|. 2 distinct but representing
  the same range instances now compare equal.
• Documentation for |vim.fn| now points to preferred Lua alternatives when
  available.
• |vim.list.unique()| and |vim.list.bisect()| now support passing a string
  as a shorthand of a `key`
• |vim.isnil()| tests if a value is `nil` or |vim.NIL|.
• |vim.nonnil()| returns the first argument which is not nil.
• |vim.npcall()| calls the function `fn` in protected-mode like |pcall()|,
  but returns `nil` on error.
• |vim.pos| can now convert between positions and buffer offsets.
• |vim.pos| and |vim.range| can now convert between mark positions.
• |vim.pos.cursor()| without arguments returns the cursor position of the
  current window.
• |vim.ui.input()| now allows setting input scope.
• |vim.log| provides a logging interface.
• |vim.pack.get()| output includes revision of a pending update.
• |vim.pack.get()| can fetch new updates before computing the output.
• |vim.pack| supports |vim.pack-manifest| of plugins.
• |vim.o| now accepts table style values for assignment.
• |vim.keycode()| returns structured info as return value 2.
• |Iter:count()| counts items in the iterator.

OPTIONS

• Lua functions/closures can be assigned to "func" and "expr" options:
  |option-value-function| (e.g. `vim.o.operatorfunc`), |expr-option-function|
  (e.g. `vim.wo.foldexpr`, `vim.bo.indentexpr`). Reading such an option:
  • ...from Lua, gets the function itself.
  • ...from Vimscript/RPC, gets a human-readable `"<Lua …>"` hint string.
• 'ttyfast' can be disabled during startup by setting |$NVIM_NOTTYFAST|.
• 'scrolloffpad' allows vertically centering cursor at the end of file.
• 'shortmess' flag |shm-u| silences undo/redo messages.
• 'statusline' supports |stl-%0{| to insert the expression result verbatim.
  The `%=` item is supported within item groups to separate alignment sections
  within the containing group until its `minwid` is reached. The truncation
  of an item group to its `maxwid` can be controlled with the `%<` item.
  The new %#(...%#) item denotes a highlight scope.
  The same applies to 'rulerformat', 'statuscolumn', 'tabline', 'winbar',
  'titlestring', and 'iconstring'.
• 'winpinned' prevents window from closing unless specifically targeted.
• 'packlockfile' sets the path used for |vim.pack-lockfile|.
• 'previewpopup' decides how the preview window is displayed.
• 'messagesopt' items "pager" and "timeout" configure the |ui2| message pager
  key and how long a message stays in the message window.

PERFORMANCE

• LSP shares identical file watcher registrations, reducing startup work in
  large workspaces.
• |treesitter-highlight| performance on large injection-heavy files improves
  by 50% to 100% by reusing edited child-tree ranges.
• Nvim architecture allows pure-Lua implementations of some `vim.fn`
  functions, which skips the Vimscript <=> Lua "bridge" (no data
  conversion/marshalling) entirely, if the `vim.fn` function is called from
  Lua.
• Internal LSP data is cleared using `table.clear`, which reduces GC and
  memory reallocation during each data reset.
• RPC client avoids string allocations when parsing Content-Length messages.
• LSP: "overscan" semantic_token range requests to avoid flicker.
• |vim.hl.range()| and |vim.hl.hl_op()| are faster for large characterwise and
  linewise regions.
• The display of multibyte text with grapheme clusters has been optimized,
  by calculating byte length and cell width of clusters in a single loop.

PLUGINS

• The zip plugin is now |zip|, a read-only archive browser built on |dir|.
  To use the legacy plugin instead: >
  :packadd old-zip
<
• provider: add bun support for Node.js plugins

STARTUP

• |--embed| with |--listen| waits for a UI on the listen address if stdin is
  not a pipe (e.g. tty or /dev/null), instead of exiting.

TERMINAL

• todo

TREESITTER

• |vim.treesitter.get_captures()| returns highlight captures at a given position,
  on a whole line, or overlapping a range. It replaces
  |vim.treesitter.get_captures_at_pos()|.
• |v_]N| |v_[N| expand selection to sibling treesitter node.
• |treesitter-highlight-conceal| can be removed by adding a `@noconceal`
  capture.
• |vim.treesitter.select()| starts or adjusts a visual selection at cursor,
  based on tree nodes.
• The `diff` treesitter parser is bundled.

TUI

• The TUI will re-query the terminal's background color when resuming from
  a suspended state, and Nvim will update 'background' accordingly.
• User can override the builtin "terminfo" via |$NVIM_TERMDEFS|. This is
  similar to Vim's |t_xx| options.

UI

• |:checkhealth| shows filewatcher info in the Performance section.
• Floating window border highlights (|hl-FloatBorder|, |hl-FloatTitle|,
  |hl-FloatFooter|) combine with the window-local |hl-Normal| background
  instead of falling back to the global background.
• These builtin "picker" menus delegate to |vim.ui.select()|:
  • :browse oldfiles
  • |:recover|
  • |:tselect|
  • |z=| (spell suggest)
• The |ui2| dialog window scrolls with the mouse wheel, by 'mousescroll'
  lines.
• The |ui2| `[+x]` "spill" indicator is highlighted with |hl-MoreMsg|.

VIMSCRIPT

• `fnamemodify(':h')` preserves logical roots for more path formats.
• |v:exitreason| is set before |QuitPre|.
• |v:startreason| indicates whether Nvim started normally or by |:restart|.
• |v:starttime| is the process start time (nanoseconds since UNIX epoch).
• |v:useractive| indicates user activity.
• |serverlist()| with `info=true` returns details for each server (own + peers).
• These Vimscript functions may be called from |api-fast| context (e.g.
  |vim.uv| timer/handle callbacks): |keytrans()|, |char2nr()|, |nr2char()|,
  |str2list()|, |strpart()|, |strcharpart()|, |strgetchar()|, |strchars()|,
  |strcharlen()|, |strlen()|, |strdisplaywidth()|, |byteidx()|, |charidx()|,
  |utf16idx()|, |tr()|, |trim()|.

==============================================================================
CHANGED FEATURES                                                 *news-changed*

These existing features changed their behavior.

• Environment variable name (`$NAME`) validity is no longer controlled by
  'isident'.
• `nvim_exec_autocmds({buf=…})` runs in the context of the target buffer.
• |SessionLoadPost| is no longer included in views saved by |:mkview|.
• |OptionSet| is no longer triggered during startup by automatic
  |'background'| detection.
• |SessionWritePre| and |SessionWritePost| are no longer triggered by
  |:mkview|, |:mkvimrc|, or |:mkexrc|.
• Editing a local directory now shows its contents in a `filetype=directory`
  buffer. See |dir|.
• |:Open| with no arguments uses the current file.
• The "buffer" key was renamed to "buf" in these functions (but the old name
  "buffer" is still accepted, for backwards compatibility):
  • |nvim_clear_autocmds()|
  • |nvim_create_autocmd()|
  • |nvim_exec_autocmds()|
  • |nvim_get_autocmds()|
• |vim.keymap.set()| and |vim.keymap.del()| accept a list of strings for `lhs`.
• 'statuscolumn' click function labels can be different across rows.
  |v:virtnum| and |v:lnum| are available during the click function callback.
• Markdown inline highlighting now conceals the backslash in backslash escapes.
• Markdown inline backslash escapes and hard line breaks no longer use the
  `@string.escape` capture.
• |vim.lsp.util.open_floating_preview()| windows (e.g. |vim.lsp.buf.hover()|)
  converted to normal windows (e.g. with |CTRL-W_H|) are no longer closed
  automatically.
• |vim.fs.normalize()| `opts.expand_env=false` key was renamed to
  `opts.plain=true` and now does not expand leading tildes ("~") in addition
  to environment variables ("expand_env" is still accepted, for backwards
  compatibility).
• |:helptags| finds help tags with the "vimdoc" |treesitter| parser (and thus
  requires it to be installed).
• `:helptags ALL` reports |E152| for "doc" directories it cannot write,
  instead of silently skipping them.
• The highlighting groups |hl-CursorLineFold| and |hl-CursorLineSign| are
  always used when 'cursorline' is set.
• |vim.lsp.util.apply_text_edits()| accepts `opts.keep_cursor`, to hold the
  cursor on the text it is on while edits move around it.
• 'tagfunc' is now also used for :tag completion.
• Some character clusters are restored to occupy two cells like they
  did prior to Nvim 0.11. These include Thai syllables like สำ and
  half-width Katakana with voicing marks ｶﾞ. The TUI renders these in
  a safe way which also supports terminals which consider these to be
  single-width.
• in script mode |-l|, |print()| now behaves more similar to standalone
  lua. Printing is done to stdout, and empty lines are not stripped.
  No translation of special characters is done, so escape sequences
  can be used when printing to a terminal.
• It is no longer allowed to change the window layout during a |DiffUpdated|
  autocommand.

REMOVED FEATURES                                                 *news-removed*

These deprecated features were removed.

• Vimscript functions ctxget(), ctxpop(), ctxpush(), ctxset(), ctxsize()
  and the "context stack". Use |nvim_get_context()| and |nvim_load_context()|
  with a script-owned list instead.
• |vim.lsp.buf.declaration()|, |vim.lsp.buf.definition()|,
  |vim.lsp.buf.type_definition()|, and |vim.lsp.buf.implementation()|
  no longer accept the `reuse_win` option.
