API
f5c56f03bb #9170 API/Lua: nvim_buf_attach: support Lua callback
82d48c0dab #9896 API: emit nvim_error_event on failed async request
b9ad12e6c2 #9992 UI/nvim_ui_attach(): add `override` option
3d1ed7c959 #9993 UI/ext_messages: learn more message kinds
8ed54bbec3 #9547 proper multiline error message for rpcrequest, API wrappers

Lua
This release introduces "Nvim-Lua standard library". See ":help lua-stdlib".
89d7e24891 #9463 Lua stdlib: vim.inspect, string functions
8e941c59ec #9740 Lua: generate documentation from docstrings
1cbe014569 #9301 lua/stdlib: Introduce vim.shared
c83926cd0a #10123 Lua: introduce vim.loop (expose libuv event-loop)
81e1dbca99 #10120 Lua: vim.schedule(cb)
1f54f68732 #10688 Lua: minimal UTF-16 support needed for LSP
6fb0020df4 #10513 Lua encoding support
    c0993ed343 Lua: support getting UTF-32 and UTF-16 sizes of replaced text
    b0e26199ec Lua: add {old_byte_size} to on_lines buffer change event

UI:
- The Nvim 0.3.4 UI protocol introduced line-based updates instead of
  legacy char-based updates. Nvim 0.4 continues to evolve the UI
  protocol. See ":help ui". Legacy UI clients are supported. See
  ":help api-contract".
9a1675b065 #6619 Floating windows
  - Can be (re)positioned, anchored, external.
  - Are real windows showing real buffers. No shortcuts, hacks, or compromises.
  - Support all features and API of normal windows, plus more.
6427894d89 #8455 Multigrid: "windows drawn on separate grids"
  - Windows are logically isolated internally.
  - Windows are sent to UIs as distinct objects, so that UIs can control
    layout instead of being stuck with the classic TUI layout.
  - Per-window font-size, dimenions, line-spacing.
  - Compositor: Internal subsystem for composing grids.
3855204f58 #6917 UIEnter, UILeave
788bcbba24 #9923 ui: ":syn blend=", 'winblend'
7cf7c0a0b8 #9575 ui: 'redrawdebug' option for flexible debugging of redrawing
5c836d2ef8 #9607 wildoptions=pum (enabled by default)
37f8df8824 #9571 UI: 'pumblend' option for semi-transparent popupmenu
c403a95a52 #9446 Visual: highlight char-at-cursor
  - Traditionally Vim's visual selection does "reverse mode", which
    perhaps conflicts with the non-blinking block cursor. But
    'guicursor' defaults to a vertical bar for selection=exclusive, and
    this confuses users who expect to see the text highlighted.

2816bc8620 #8349 edit.c: Disable indent during completion
58f505dc74 #9829 startup: remove TUI init special-case
    Historically Vim/Nvim does backflips to handle input and show messages
    before a UI is available. This logical contradiction was already fixed
    for remote UIs (#9024 c236e80cf3). Fixing it also for the TUI avoids
    problems on Windows, simplifies the logic, and avoids races like #9959.

Packages Debian CI Downloads

Neovim is a project that seeks to aggressively refactor Vim in order to:

See the Introduction wiki page and Roadmap for more information.

Features

See :help nvim-features for the full list!

Install from package

Pre-built packages for Windows, macOS, and Linux are found on the Releases page.

Managed packages are in Homebrew, Debian, Ubuntu, Fedora, Arch Linux, Gentoo, and more!

Install from source

The build is CMake-based, but a Makefile is provided as a convenience.

make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install

To install to a non-default location:

make CMAKE_INSTALL_PREFIX=/full/path/
make install

To skip bundled (third-party/*) dependencies:

  1. Install the dependencies using a package manager.
    sudo apt install gperf luajit luarocks libuv1-dev libluajit-5.1-dev libunibilium-dev libmsgpack-dev libtermkey-dev libvterm-dev
    sudo luarocks build mpack
    sudo luarocks build lpeg
    sudo luarocks build inspect
    
  2. Build with USE_BUNDLED=OFF:
    make CMAKE_BUILD_TYPE=RelWithDebInfo USE_BUNDLED=OFF
    sudo make install
    

To inspect the build, these CMake features are useful:

  • cmake --build build --target help lists all build targets.
  • build/CMakeCache.txt (or cmake -LAH build/) contains the resolved values of all CMake variables.
  • build/compile_commands.json shows the full compiler invocations for each translation unit.

See the Building Neovim wiki page for details.

Transitioning from Vim

See :help nvim-from-vim for instructions.
