   * Add ~lsp-flush-delayed-changes-before-next-message~ customization point to enforce throttling document change notifications.
   * Fix bug in ~rust-analyzer.check.features~ configuration via ~lsp-rust-checkonsave-features~ Emacs setting: we were defaulting to ~[]~, but ~rust-analyzer~ defaults to inheriting the value from ~rust-analyzer.cargo.features~. The bug resulted in code hidden behind features not getting type checked when those features were enabled by setting ~rust-analyzer.cargo.features~ via the ~lsp-rust-features~ Emacs setting.
   * Change ~ruff-lsp~ to ~ruff~ for python lsp client. All ~ruff-lsp~ customizable variable change to ~ruff~. Lsp server command now is ~["ruff" "server"]~ instead of ~["ruff-lsp"]~.
+  * Add futhark support
 
 ** 9.0.0
   * Add language server config for QML (Qt Modeling Language) using qmlls.
