+
+↠ To improve syntax highlighting for [Pandoc][], support for the [vim-pandoc/vim-pandoc-syntax][] plugin has been implemented.
+Most groups are linked to existing Markdown groups to ensure a consistent style across languages and different plugins.

+<summary><strong>Prevent aggressive error highlighting</strong> — #269 ⇄ #270 (⊶ e3e8a75c) by <a href="https://github.com/jan-xyz" target="_blank" rel="noreferrer">@jan-xyz</a></summary>
+
+↠ The `TSError` group is used to [highlight syntax/parser errors][nvim-treesitter/nvim-treesitter-blob-fb5d6e04#l493-l495] which caused an aggressive styling where the background color of many syntax elements was rendered with `nord11` during typing. This is a known problem and was fixed by many other themes by removing the group again. One of the [core maintainers of `nvim-treesitter` provided a solution by remapping groups][nvim-treesitter/nvim-treesitter#78#comment-647140700] and also mentioned that the group is [styled by the `nvim-treesitter` plugin but the active theme][nvim-treesitter/nvim-treesitter#1016#comment-797049591].
+
+Syntax errors can still be highlighted through linters and parsers like [Neovim's LSP][neovim/nvim-lspconfig] can still be used instead to highlight errors with the correct style, e.g. only change the foreground color of a single word.

+
+↠ Neovim [version 0.5][neovim/neovim-v0.5.0] is a long-time awaited update that introduces features like support for [tree-sitter][tree-sitter/tree-sitter] via [nvim-treesitter][nvim-treesitter/nvim-treesitter] and [LSP][neovim-docs-lsp] via [nvim-lspconfig][neovim/nvim-lspconfig].
+Even though Neovim divides more and more from Vim through specific features like first-class Lua support with custom APIs, the highlighting for tree-sitter is achieved through “normal“ syntax highlighting groups. Most of the groups are already [linked by the `nvim-treesitter` plugin by default][nvim-treesitter/nvim-treesitter-blob-90f15d9] so only a few groups have been adjusted for now to fit the Nord style.
+
+⚠️ Note that this is the first iteration and **it is very likely that there will be inconsistencies compared to the current highlighting when using “normal“ Vim plugins per language**. Please **report any problem** you find so that the support for tree-sitter can be improved continuously!
