BREAKING CHANGES                                                *news-breaking*

The following changes may require adaptations in user config or plugins.

• |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()`.

NEW FEATURES                                                    *news-features*

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

• Added |vim.lsp.status()| to consume the last progress messages as a string.

• Neovim's LSP client now always saves and restores named buffer marks when
  applying text edits.

• Nvim 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`.

• |vim.iter()| provides a generic iterator interface for tables and Lua
  iterators |luaref-in|.

• Added |vim.ringbuf()| to create ring buffers.

• Added |vim.keycode()| for translating keycodes in a string.

• Added |vim.treesitter.query.omnifunc()| for treesitter query files (set by
  default).

• |'smoothscroll'| option to scroll by screen line rather than by text line
  when |'wrap'| is set.

• |Query:iter_matches()| now has the ability to set the maximum start depth
  for matches.

• Added inline virtual text support to |nvim_buf_set_extmark()|.

• 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.system()| for running system commands.

• Added |nvim_win_text_height()| to compute the number of screen lines occupied
  by a range of text in a given window.

• |nvim_set_keymap()| and |nvim_del_keymap()| now support abbreviations.

• Builtin TUI can now recognize "super" (|<D-|) and "meta" (|<T-|) modifiers in a
  terminal emulator that supports |tui-csiu|.

• Implemented LSP inlay hints: |vim.lsp.inlay_hint()|
  https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#textDocument_inlayHint

• Bundled treesitter parser and queries (highlight, folds) for Markdown,
  Python, and Bash.

• |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.

CHANGED FEATURES                                                 *news-changed*

The following changes to existing APIs or features add new behavior.

• |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.)

• |vim.region()| can use a string accepted by |getpos()| as position.

• vim.diagnostic.config() now accepts a function for the virtual_text.prefix
  option, which allows for rendering e.g., diagnostic severities differently.

• Defaults:
  • '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()|.

==============================================================================
