Lua
This release introduces "Nvim-Lua standard library". See ":help lua-stdlib".
89d7e24 #9463 Lua stdlib: vim.inspect, string functions
8e941c5 #9740 Lua: generate documentation from docstrings
1cbe014 #9301 lua/stdlib: Introduce vim.shared
c83926c #10123 Lua: introduce vim.loop (expose libuv event-loop)
81e1dbc #10120 Lua: vim.schedule(cb)
1f54f68 #10688 Lua: minimal UTF-16 support needed for LSP
6fb0020 #10513 Lua encoding support
    c0993ed Lua: support getting UTF-32 and UTF-16 sizes of replaced text
    b0e2619 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".
9a1675b #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.
6427894 #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.
3855204 #6917 UIEnter, UILeave
788bcbb #9923 ui: ":syn blend=", 'winblend'
7cf7c0a #9575 ui: 'redrawdebug' option for flexible debugging of redrawing
5c836d2 #9607 wildoptions=pum (enabled by default)
37f8df8 #9571 UI: 'pumblend' option for semi-transparent popupmenu
c403a95 #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.

2816bc8 #8349 edit.c: Disable indent during completion
58f505d #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 c236e80). Fixing it also for the TUI avoids
    problems on Windows, simplifies the logic, and avoids races like #9959.
