 The following changes may require adaptations in user config or plugins.
 
-• Cscope support is now removed (see |cscope| and |nvim-features-removed|):
-  - Commands removed:
-    - `:cscope`
-    - `:lcscope`
-    - `:scscope`
-    - `:cstag`
-  - Options removed:
-    - `cscopepathcomp`
-    - `cscopeprg`
-    - `cscopequickfix`
-    - `cscoperelative`
-    - `cscopetag`
-    - `cscopetagorder`
-    - `cscopeverbose`
-  - Eval functions removed:
-    - `cscope_connection()`
-
-  Note: support for |ctags| remains with no plans to remove.
-
-  See https://github.com/neovim/neovim/pull/20545 for more information.
-
-• `:hardcopy` is now removed (see |hardcopy| and |nvim-features-removed|):
-  - Commands removed:
-    - `:hardcopy`
-  - Options removed:
-    - `printdevice`
-    - `printencoding`
-    - `printexpr`
-    - `printfont`
-    - `printheader`
-    - `printmbcharset`
-
-• libiconv is now a required build dependency.
+• In some cases, the cursor in the Nvim |TUI| would blink even without
+  configuring 'guicursor' as mentioned in |cursor-blinking|. This was a bug
+  that has now been fixed. If your cursor has stopped blinking, add the
+  following (or similar, adapted to user preference) to your |config| file: >vim
+
+    set guicursor+=n-v-c:blinkon500-blinkoff500
+<
+• |vim.tbl_islist()| now checks whether a table is actually list-like (i.e.,
+  has integer keys without gaps and starting from 1). For the previous
+  behavior (only check for integer keys, allow gaps or not starting with 1),
+  use |vim.tbl_isarray()|.
+
+• "#" followed by a digit no longer stands for a function key at the start of
+  the lhs of a mapping.
+
+• `:behave` was removed.
+  - If you used `:behave xterm`, the following is equivalent: >vim
+
+    set mousemodel=extend
+<
+  - If you used `:behave mswin`, the following is equivalent: >vim
+
+    set selection=exclusive
+    set selectmode=mouse,key
+    set mousemodel=popup
+    set keymodel=startsel,stopsel
+<
+• When switching windows, |CursorMoved| autocommands trigger when Nvim is back
+  in the main loop rather than immediately. This is more compatible with Vim.
+
+• |-l| ensures output ends with a newline if the script prints messages and
+  doesn't cause Nvim to exit.
+
+• |LspRequest| and LspProgressUpdate (renamed to |LspProgress|) autocmds were
+  promoted from a |User| autocmd to first class citizen.
+
+• Renamed `vim.treesitter.playground` to `vim.treesitter.dev`.
+
+• Removed functions from the |vim.json| module:
+  • Unnecessary, undocumented functions which caused global side-effects.
+  • `vim.json.null` is redundant with `vim.NIL`.
+  • `vim.json.array_mt` (and related) is redundant with `vim.empty_dict()`.
+
+• Removed some Vim 5.0<= option compatibilities:
+  • |'backspace'| no longer supports number values. Instead:
+    • for `backspace=0` set `backspace=` (empty)
+    • for `backspace=1` set `backspace=indent,eol`
+    • for `backspace=2` set `backspace=indent,eol,start` (default behavior in Nvim)
+    • for `backspace=3` set `backspace=indent,eol,nostop`
+  • |'backupdir'| and |'directory'| will no longer remove a `>` at the start
+    of the option.
+
+• |LanguageTree:parse()| will no longer parse injections by default and
+  now requires an explicit range argument to be passed. If injections are
+  required, provide an explicit range via `parser:parse({ start_row, end_row })`.
+
+• Float window support hide and show by setting `hide` on `nvim_open_win` and
+  `nvim_win_set_config`.
+
+• |vim.lsp.util.parse_snippet()| will now strictly follow the snippet grammar
+  defined by LSP, and hence previously parsed snippets might now be considered
+  invalid input.
+
+• |OptionSet| autocommand args |v:option_new|, |v:option_old|,
+  |v:option_oldlocal|, |v:option_oldglobal| now have the type of the option
+  instead of always being strings. |v:option_old| is now the old global value
+  for all global-local options, instead of just string global-local options.
+
+• Local value for a global-local number/boolean option is now unset when
+  the option is set (e.g. using |:set| or |nvim_set_option_value()|) without a
+  scope, which means they now behave the same way as string options.
+
+• Signs placed through the legacy |sign-commands| are now stored and displayed
+  as |extmarks| internally. Along with the following changes:
+  • A sign placed twice in the same group with the same identifier will be moved.
+  • Legacy signs are always deleted along with the line it is placed on.
+  • Legacy and extmark signs will show up in both |:sign-place-list| and |nvim_buf_get_extmarks()|.
+  • Legacy and extmark signs are displayed and listed with the same priority:
+      line number -> priority -> sign id -> recently placed

 ==============================================================================
 NEW FEATURES                                                    *news-features*
 
-The following new APIs or features were added.
+The following new APIs and features were added.
+
+• Performance:
+  • 'diffopt' "linematch" scoring algorithm now favours larger and less groups
+    https://github.com/neovim/neovim/pull/23611
+  • Treesitter highlighting now parses injections incrementally during
+    screen redraws only for the line range being rendered. This significantly
+    improves performance in large files with many injections.
+
+• |vim.iter()| provides a generic iterator interface for tables and Lua
+  iterators |for-in|.
+
+• Added |vim.ringbuf()| to create ring buffers.
 
-• |nvim_open_win()| now accepts a relative `mouse` option to open a floating win
-  relative to the mouse. Note that the mouse doesn't update frequently without
-  setting `vim.o.mousemoveevent = true`
+• Added |vim.keycode()| for translating keycodes in a string.
 
-• EditorConfig support is now builtin. This is enabled by default and happens
-  automatically. To disable it, users should add >lua
+• |'smoothscroll'| option to scroll by screen line rather than by text line
+  when |'wrap'| is set.
 
-    vim.g.editorconfig = false
-<
-  (or the Vimscript equivalent) to their |config| file.
+• Added inline virtual text support to |nvim_buf_set_extmark()|.
 
-• Run Lua scripts from your shell using |-l|. >
-      nvim -l foo.lua --arg1 --arg2
-<  Also works with stdin: >
-      echo "print(42)" | nvim -l -
+• 'foldtext' now supports virtual text format. |fold-foldtext|
 
-• Added a |vim.lsp.codelens.clear()| function to clear codelenses.
+• The terminal buffer now supports reflow (wrapped lines adapt when the buffer
+  is resized horizontally). Note: Lines that are not visible and kept in
+  |'scrollback'| are not reflown.
 
-• |vim.inspect_pos()|, |vim.show_pos()| and |:Inspect| allow a user to get or show items
-  at a given buffer position. Currently this includes treesitter captures,
-  semantic tokens, syntax groups and extmarks.
+• |vim.system()| for running system commands.
 
-• Added support for semantic token highlighting to the LSP client. This
-  functionality is enabled by default when a client that supports this feature
-  is attached to a buffer. Opt-out can be performed by deleting the
-  `semanticTokensProvider` from the LSP client's {server_capabilities} in the
-  `LspAttach` callback.
+• Added |nvim_win_text_height()| to compute the number of screen lines occupied
+  by a range of text in a given window.
 
-  See |lsp-semantic_tokens| for more information.
+• |nvim_set_keymap()| and |nvim_del_keymap()| now support abbreviations.
 
-• |vim.treesitter.show_tree()| opens a split window showing a text
-  representation of the nodes in a language tree for the current buffer.
+• Better cmdline completion for string option value. |complete-set-option|
 
-• Added support for the `willSave` and `willSaveWaitUntil` capabilities to the
-  LSP client. `willSaveWaitUntil` allows a server to modify a document before it
-  gets saved. Example use-cases by language servers include removing unused
-  imports, or formatting the file.
+• Builtin TUI can now recognize "super" (|<D-|) and "meta" (|<T-|) modifiers in a
+  terminal emulator that supports |tui-csiu|.
 
-• Treesitter syntax highlighting for `help` files now supports highlighted
-  code examples. To enable, create a `.config/nvim/ftplugin/help.lua` with
-  the contents >lua
-    vim.treesitter.start()
-<
-  Note: Highlighted code examples are only available in the Nvim manual, not
-  in help files taken from Vim. The treesitter `help` parser is also work in
-  progress and not guaranteed to correctly highlight every help file in the
-  wild.
+• Editor
+  • By default, the swapfile "ATTENTION" |E325| dialog is skipped if the
+    swapfile is owned by a running Nvim process, instead of prompting. If you
+    always want the swapfile dialog, delete the default SwapExists handler:
+    `autocmd! nvim_swapfile`. |default-autocmds|
+
+• LSP
+  • LSP method names are available in |vim.lsp.protocol.Methods|.
+  • Implemented LSP inlay hints: |lsp-inlay_hint|
+    https://microsoft.github.io/language-server-protocol/specification/#textDocument_inlayHint
+  • Implemented pull diagnostic textDocument/diagnostic: |vim.lsp.diagnostic.on_diagnostic()|
+    https://microsoft.github.io/language-server-protocol/specification/#textDocument_diagnostic
+  • Added |vim.lsp.status()| to consume the last progress messages as a string.
+  • LSP client now always saves and restores named buffer marks when applying
+    text edits.
+  • LSP client now supports the `positionEncoding` server capability. If a server
+    responds with the `positionEncoding` capability in its initialization
+    response, Nvim automatically sets the client's `offset_encoding` field.
+  • Dynamic registration of LSP capabilities. An implication of this change is
+    that checking a client's `server_capabilities` is no longer a sufficient
+    indicator to see if a server supports a feature. Instead use
+    `client.supports_method(<method>)`. It considers both the dynamic
+    capabilities and static `server_capabilities`.
+  • Added a new `anchor_bias` option to |lsp-handlers| to aid in positioning of
+    floating windows.
+
+• Treesitter
+  • Bundled parsers and queries (highlight, folds) for Markdown, Python, and
+    Bash.
+  • Added |vim.treesitter.query.omnifunc()| for treesitter query files (set by
+    default).
+  • |Query:iter_matches()| now has the ability to set the maximum start depth
+    for matches.
+  • `@injection.language` now has smarter resolution and will now fallback to language aliases and/or attempt lower case variants of the text.
+    language via aliases (e.g., filetype) registered via
+    `vim.treesitter.language.register`.
+  • The `#set!` directive now supports `injection.self` and `injection.parent` for injecting either the current node's language
+    or the parent LanguageTree's language, respectively.
+  • Added `vim.treesitter.query.edit()`, for live editing of treesitter
+    queries.
+  • Improved error messages for query parsing.
+  • Added |vim.treesitter.foldtext()| to apply treesitter highlighting to
+    foldtext.
+
+• |vim.ui.open()| opens URIs using the system default handler (macOS `open`,
+  Windows `explorer`, Linux `xdg-open`, etc.)
+
+• |vim.wo| can now be double indexed for |:setlocal| behaviour. Currently only
+  `0` for the buffer index is currently supported.
 
-• |vim.secure.trust()|, |:trust| allows the user to manage files in trust
-  database.
+• Lua type annotations for:
+  • `vim.*`
+  • `vim.fn.*`
+  • `vim.api.*`
 
-• |vim.diagnostic.open_float()| (and therefore |vim.diagnostic.config()|) now
-  accepts a `suffix` option which, by default, renders LSP error codes.
-  Similarly, the `virtual_text` configuration in |vim.diagnostic.config()| now
-  has a `suffix` option which does nothing by default.
+• Improved messages for type errors in `vim.api.*` calls (including `opts` params)
 
-• |vim.fs.dir()| now has a `opts` argument with a depth field to allow
-  recursively searching a directory tree.
+• Functions that take a severity as an optional parameter (e.g.
+  |vim.diagnostic.get()|) now also accept a list of severities |vim.diagnostic.severity|
 
-• |vim.secure.read()| reads a file and prompts the user if it should be
-  trusted and, if so, returns the file's contents.
+• New RPC client type `msgpack-rpc` is added for `nvim_set_client_info` to
+  support fully MessagePack-RPC compliant clients.
 
-• When using Nvim inside tmux 3.2 or later, the default clipboard provider
-  will now copy to the system clipboard. |provider-clipboard|
+• Floating windows can now show footer with new `footer` and `footer_pos`
+  config fields. Uses |hl-FloatFooter| by default.
 
-• |'showcmdloc'| option to display the 'showcmd' information in the
-  status line or tab line. A new %S statusline item is available to place
-  the 'showcmd' text in a custom 'statusline'. Useful for when |'cmdheight'|
-  is set to 0.
+• The |:terminal| command now accepts some |:command-modifiers| (specifically
+  |:horizontal| and those that affect splitting a window).
 
-• |'splitkeep'| option to control the scroll behavior of horizontal splits.
+• |vim.lsp.util.locations_to_items()| sets the `user_data` of each item to the
+  original LSP `Location` or `LocationLink`.
 
-• |'statuscolumn'| option to customize the area to the side of a window,
-  normally containing the fold, sign and number columns. This new option follows
-  the 'statusline' syntax and can be used to transform the line numbers, create
-  mouse click callbacks for |signs|, introduce a custom margin or separator etc.
+• |$NVIM_APPNAME| can be set to a relative path instead of only a name.
 
-• |nvim_select_popupmenu_item()| now supports |cmdline-completion| popup menu.
+• Added |:fclose| command.
 
-• |'diffopt'| now includes a `linematch` option to enable a second-stage diff
-  on individual hunks to provide much more accurate diffs. This option is also
-  available to |vim.diff()|
+• Added |vim.snippet| for snippet expansion support.
 
-  See https://github.com/neovim/neovim/pull/14537.
+• 'complete' option supports "f" flag for completing buffer names.
 
-• |vim.diagnostic.is_disabled()| checks if diagnostics are disabled in a given
-  buffer or namespace.
+• Added |vim.base64.encode()| and |vim.base64.decode()| for encoding and decoding
+  strings using Base64 encoding.
 
-• |--remote-ui| option was added to connect to a remote instance and display
-  in it in a |TUI| in the local terminal. This can be used run a headless nvim
-  instance in the background and display its UI on demand, which previously
-  only was possible using an external UI implementation.
+• The |TermResponse| autocommand event can be used with |v:termresponse| to
+  read escape sequence responses from the terminal.
 
-• Several improvements were made to make the code generation scripts more
-  deterministic, and a `LUA_GEN_PRG` build parameter has been introduced to
-  allow for a workaround for some remaining reproducibility problems.
+• A clipboard provider which uses OSC 52 to copy the selection to the system
+  clipboard is now bundled by default and will be automatically enabled under
+  certain conditions. |clipboard-osc52|
 
-• |:highlight| now supports an additional attribute "altfont".
+• The 'termsync' option asks the terminal emulator to buffer screen updates
+  until the redraw cycle is complete. Requires support from the terminal.
+
+• Added |vim.text.hexencode()| and |vim.text.hexdecode()| to convert strings
+  to and from byte representations.

+CHANGED FEATURES                                                 *news-changed*
 
 The following changes to existing APIs or features add new behavior.
 
-• 'exrc' now supports `.nvim.lua` file.
-• 'exrc' is no longer marked deprecated.
+• |vim.tbl_contains()| now works for general tables and allows specifying a
+  predicate function that is checked for each value. (Use |vim.list_contains()|
+  for checking list-like tables (integer keys without gaps) for literal values.)
 
-• The |TUI| is changed to run in a separate process (previously, a separate
-  thread was used). This is not supposed to be a visible change to the user,
-  but might be the cause of subtle changes of behavior and bugs.
+• |vim.region()| can use a string accepted by |getpos()| as position.
 
-  Previously, the TUI could be disabled as a build time feature (+tui/-tui),
-  resulting in a nvim binary which only could be run headless or embedded
-  in an external process. As of this version, TUI is always available.
+• vim.diagnostic.config() now accepts a function for the virtual_text.prefix
+  option, which allows for rendering e.g., diagnostic severities differently.
 
-• API calls now show more information about where an exception happened.
+• Defaults:
+  • On Windows 'isfname' does not include ":". Drive letters are handled
+    correctly without it. (Use |gF| for filepaths suffixed with ":line:col").
+  • 'comments' includes "fb:•".
+  • 'shortmess' includes the "C" flag.
+  • Automatic linting of treesitter query files (see |ft-query-plugin|).
+    Can be disabled via: >lua
+      vim.g.query_lint_on = {}
+<
+  • Enabled treesitter highlighting for treesitter query files.
+
+• The `workspace/didChangeWatchedFiles` LSP client capability is now enabled
+  by default.
+
+• |LspRequest| autocmd callbacks now contain additional information about the LSP
+  request status update that occurred.
+
+• `:source` without arguments treats a buffer with its 'filetype' set to "lua"
+  as Lua code regardless of its extension.
+
+• |:checkhealth| buffer now implements |folding|. The initial folding status is
+  defined by the 'foldenable' option.
+
+• |:Man| now respects 'wrapmargin'
+
+• |gx| now uses |vim.ui.open()| and not netrw. To customize, you can redefine
+  `vim.ui.open` or remap `gx`. To continue using netrw (deprecated): >vim
+  :call netrw#BrowseX(expand(exists("g:netrw_gx")? g:netrw_gx : '<cfile>'), netrw#CheckIfRemote())<CR>
+
+• |vim.lsp.start()| now maps |K| to use |vim.lsp.buf.hover()| if the server
+  supports it, unless |'keywordprg'| was customized before calling
+  |vim.lsp.start()|.
+
+• Terminal buffers started with no arguments (and use 'shell') close
+  automatically if the job exited without error, eliminating the (often
+  unwanted) "[Process exited 0]" message.
+
+• |vim.diagnostic.config()| now accepts virtual text relevant options to
+  |nvim_buf_set_extmark()| (e.g. "virt_text_pos" and "hl_mode") in its
+  "virtual_text" table, which gives users more control over how diagnostic
+  virtual text is displayed.
+
+• Extmarks now fully support multi-line ranges, and a single extmark can be
+  used to highlight a range of arbitrary length. The |nvim_buf_set_extmark()|
+  API function already allowed you to define such ranges, but highlight regions
+  were not rendered consistently for a range that covers more than one line break.
+  This has now been fixed. Signs defined as part of a multi-line extmark also
+  apply to every line in the range, not just the first.
+  In addition, |nvim_buf_get_extmarks()| has gained an "overlap" option to
+  return such ranges even if they started before the specified position.
+
+• Extmarks can opt-out of precise undo tracking using the new "undo_restore"
+  flag to |nvim_buf_set_extmark()|
+
+• Extmarks can be automatically hidden or removed using the new "invalidate"
+  flag to |nvim_buf_set_extmark()|
+
+• LSP hover and signature help now use Treesitter for highlighting of Markdown
+  content.
+  Note that syntax highlighting of code examples requires a matching parser
+  and may be affected by custom queries.
+
+• Support for rendering multibyte characters using composing characters has been
+  enhanced. The maximum limit have been increased from 1+6 codepoints to
+  31 bytes, which is guaranteed to fit all chars from before but often more.
+
+  NOTE: the regexp engine still has a hard-coded limit of considering
+  6 composing chars only.
+
+• |vim.wait()| is no longer allowed to be called in |api-fast|.

 REMOVED FEATURES                                                 *news-removed*
 
 The following deprecated functions or APIs were removed.
 
-• It is no longer possible to scroll the whole screen when showing messages
-  longer than 'cmdheight'. |msgsep| is now always enabled even if 'display'
-  doesn't contain the "msgsep" flag.
+• Vimball support is removed.
+  - :Vimuntar command removed.
 
-• `filetype.vim` is removed in favor of |lua-filetype|
-  (Note that filetype logic and tests still align with Vim, so additions or
-  changes need to be contributed there first.)
-  See https://github.com/neovim/neovim/pull/20674.
+• Support for legacy treesitter injection queries is removed.
+
+• Removed 'shortmess' flags:
+  - |shm-f|. Always uses "(3 of 5)", never "(file 3 of 5)"
+  - |shm-i|. Always use "[noeol]".
+  - |shm-x|. Always use "[dos]", "[unix]" and "[mac]"
+  - |shm-n|. Always use "[New]".
