 Note that rascal-lsp releases are bundled with VS Code releases, however due to historic reasons, their versions do not align. Until they do we'll denote both the VS Code and the rascal LSP release next to each other.
 
+## Release 2.21.1 (VS Code: 0.12.1)
+
+* The type-checker got a lot faster, especially if you're editing a single file in a larger project.
+* Various bugfixes in:
+    * The rename functionality
+    * The code actions
+    * The type-checker

 ## Release 2.21.0 (VS Code: 0.12.0)
 
 * New feature: The "Rename Symbol" command (default: `F2`) is now supported for all identifiers in Rascal modules. Renaming is safe, so the semantics of Rascal code before/after renaming is the same.
