+Neovim is still the [world's most-loved editor](https://insights.stackoverflow.com/survey/2021#most-loved-dreaded-and-wanted-new-collab-tools-love-dread).

+
+Here are some highlights from Neovim 2022 (Nvim 0.8) development.
+
+## UI
+
+## LSP
+
+- LSP documentation hover now uses Nvim's builtin markdown parsing to render
+  markdown in docstrings.
+- LSP client now has support for fswatch, to improve efficiency and performance
+  of watching many files in a big workspace.
+- inlay hint support: [neovim/neovim@643546b](https://github.com/neovim/neovim/commit/643546b82b4bc0c29ca869f81af868a019723d83)
+    - leverages the new inline virtual text: [neovim/neovim@efa9b29](https://github.com/neovim/neovim/commit/efa9b299a7cb68909e9bcd290e4d12bcb6d0bb03).
+
+## Editor
+
+- `grepprg` now use ripgrep if available
+    [neovim/neovim@20b3867](https://github.com/neovim/neovim/commit/20b38677c22b0ff19ea54396c7718b5a8f410ed4)
+
+## Performance
+
+## Defaults
+
+- Neovim-branded colorscheme [neovim/neovim@64a1402](https://github.com/neovim/neovim/commit/64a14026d76ba1798d91e15a941fcb6af7cbc5ad)
+- Built in commenting: https://github.com/neovim/neovim/pull/28176
+
+## TUI
+
+- osc52 clipboard [neovim/neovim@748bc4d](https://github.com/neovim/neovim/commit/748bc4d22d35b40f0795015e5d93113b526adf22)
+- osc8: treesitter queries can annotate text as URLs, which Nvim will then emit
+  to the host terminal wrapped in OSC 8. Supporting terminals will activate
+  these tokens as hyperlinks.
+- support Super and Meta keys [feat(tui): support Super and Meta modifiers neovim/neovim#24357](https://github.com/neovim/neovim/pull/24357)
+
+## Treesitter (syntax parsing)
+
+Developing treesitter grammars is now as accessible as developing plugins.
+With `:InspectTree` and `:EditQuery` you can start experimenting with the
+treesitter parsing of any buffer (C, Lua, vimscript, vimdoc, markdown are builtin).
+And these views are connected to the buffer: when you move your cursor in the
+AST or the query, the relevant buffer text is highlighted, so you can instantly see how
+changes in one affect the other.
+
+## API
+
+## Lua
+
+- `vim.system()`: [neovim/neovim@c0952e6](https://github.com/neovim/neovim/commit/c0952e62fd0ee16a3275bb69e0de04c836b39015)
+- Nvim ships with annotations for `vim.fn.xxx`, so LSP servers like LuaLS can show docstrings and type information. [neovim/neovim@42333ea](https://github.com/neovim/neovim/commit/42333ea98dfcd2994ee128a3467dfe68205154cd)
+- `vim.iter`: [neovim/neovim@ab1edec](https://github.com/neovim/neovim/commit/ab1edecfb7c73c82c2d5886cb8e270b44aca7d01)
+- `vim.snippet`
+- `vim.keycode`: [neovim/neovim@7e70ca0](https://github.com/neovim/neovim/commit/7e70ca0b4808bb9d8f19c28c8f93e8f2b9e0d0f0)
+- base64 module [neovim/neovim@224f303](https://github.com/neovim/neovim/commit/224f303ee54c54d2147f03010385e8cc48e42869)
+
+## Maintenance
+
+- LuaLS type checking, annotations
+- Work by dundargoc, zeer
+
+## Documentation
+
+Automated generation of the [online Nvim documentation](https://neovim.io/doc/user/) was rewritten by replacing an old AWK script with Lua + tree-sitter. [We can have nice things.](https://twitter.com/justinmk/status/1577344345736466432)
+
+- massive improvements by lewis, `@inlinedoc`, performance, ...
+
+Compare the old layout (left) to the new one (right):

+
+## Job control
+
+## RPC
+
+Nvim UIs are just (inverted) plugins. And `nvim` itself is a [self-hosting UI](https://github.com/neovim/neovim/pull/18375): when you run `nvim` in a terminal, it starts the TUI as a `nvim --embed` child process.
+
+![](/images/2023/3_1609951283833716739.jpg)
+
+Just like Nvim GUIs, you can connect the `nvim` TUI to any Nvim server to see its UI! You can try it right now:
+
+1. Start a server at address `./foo` (creates a `foo` file in the current directory):
+   ```
+   nvim --listen ./foo
+   ```
+2. From a different terminal (in the same directory as `./foo`), connect `nvim` to the server:
+   ```
+   nvim --remote-ui --server ./foo
+   ```
+
+## Deprecations
+
+
+
+
+## Holiness
+
+Developing with the holistic system in mind. Thinking about long-term effects,
+composability of concepts and economy of interfaces.
+
+examples of devs working to arrive at a long-term solution instead of short-term hacks:
+- `v:completed_item` and `CompleteChanged` enhancements which avoided new concepts ("attach to completion provider") & surface area for LSP completion support.
+- diagnostic `goto_next(severity=nil)` instead of special-case `severity="auto"`.
+- echanovski reporting performance-based test failures, and rewriting `vim.deprecate()` to be faster to remove subtle costs of our evolution strategy.
+- dundar help with test conventions and quality, which improves life for new and existing contributors.
+- nvim_open_win() supports all kinds of windows instead of only floats. this was difficult and careful work that resulted in a much better interface.
+
+## Future
+
+upcoming:
+- build.zig : our build system is in better shape than ever (it's fast, "just
+  works" for users starting from zero, and maintainable). And having mastered
+  cmake, yet we're exploring zig to replace it all. This is one of those
+  relatively cheap side-quests that could yield extreme benefits
+  (cross-compilation, reduced maintenance costs, avoidance of cmake baggage), or
+  we could put it on ice for years or forever. Being able to probe these
+  forbidden ideas is extremely powerful.
+- utf8proc potentially improves our unicode support. the grapheme algorithm is much better.
+  utf8proc contains all the data which now is in unicode_tables.generated.h internally.
