# Release 0.9 {#sec-release-0-9}

## Breaking changes

- Nixpkgs has merged a fully incompatible rewrite of
  `vimPlugins.nvim-treesitter`. Namely, it changes from the frozen `master`
  branch to the new main branch. This change also affects how grammars are
  built, and forces us to change a few things around.
  - We must now use `"nvim-treesitter".setup` over the old `.configs`.
    Additionally, built grammars **no longer include queries by default**,
    therefore queries not managed by nvf will lack their respective syntax
    highlighting capabilities.

## Changelog {#sec-release-0-9-changelog}

[suimong](https://github.com/suimong):

- Fix `vim.tabline.nvimBufferline` where `setupOpts.options.hover` requires
  `vim.opt.mousemoveevent` to be set.

[thamenato](https://github.com/thamenato):

- Attempt to adapt nvim-treesitter to (breaking) Nixpkgs changes. Some
  treesitter grammars were changed to prefer `grammarPlugins` over
  `builtGrammars`.
