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.

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 (#9024c236e80cf3). Fixing it also for the TUI avoids
problems on Windows, simplifies the logic, and avoids races like #9959.
