Summary

Upgrades tree-sitter-typescript from 0.21.2 to 0.23.2 — the latest version that is compatible with the current tree-sitter@0.21.1 core (its peer dependency is ^0.21.0).

What Changed

Package	Before	After
tree-sitter-typescript	0.21.2	0.23.2

All other tree-sitter dependencies are unchanged.

Why tree-sitter-typescript@0.23.2?

The 0.23.x series of the TypeScript grammar brings:

• Improved TypeScript 5.x support (const type parameters, variadic tuple labels, override keyword, decorator placement)
• More accurate JSX/TSX parsing edge cases
• Improved handling of satisfies and using keywords

The update is drop-in compatible: the peer dep ^0.21.0 is satisfied by our tree-sitter@0.21.1.

Why Not Upgrade tree-sitter Core?

Investigated a coordinated ecosystem upgrade (tree-sitter 0.21.1→0.22.x or 0.25.x). Found the ecosystem is currently fragmented:

Package	Current	Latest	Requires tree-sitter
tree-sitter-typescript@0.23.2	0.21.2	0.23.2	^0.21.0 (0.21.x only)
tree-sitter-java@0.23.5	0.23.5	0.23.5	^0.21.1 (0.21.x only)
tree-sitter-rust@0.24.0	0.21.0	0.24.0	^0.22.1 (0.22.x only)
tree-sitter-c-sharp@0.23.5	0.23.1	0.23.5	^0.25.0 (0.25.x)
tree-sitter-go@0.25.x	0.21.2	0.25.x	^0.25.0 (0.25.x)

There is no single tree-sitter version that satisfies all parsers at their latest. A full ecosystem upgrade must wait until all language grammars align on a common tree-sitter version. This is tracked in memory for a future run.

Test Status
