Build up-to-date checks now track package.json inputs (
042a471)
The incremental/build pipeline now consults package.json cache entries when deciding whether outputs are stale, so dependency/package metadata changes can trigger the right rebuilds. This tightens up up-to-date detection around project references and dependency updates.
Conditional type base-constraint recursion is capped (
288f23d)
computeBaseConstraint now routes conditional types through a dedicated constraint path with a recursion-depth guard, preventing runaway base-constraint expansion on distributive conditionals. This addresses a real compiler correctness/stability issue around deeply recursive conditional types.
AST child iteration is devirtualized for speed (e190472)
Node.ForEachChild is now generated as a kind-switch dispatch to concrete node implementations, and IterChildren is implemented directly on Node to avoid interface-based escape-analysis penalties. The change is explicitly aimed at keeping visitors/closures on the stack and making child traversal cheaper.
Internal symbol names are no longer leaked in help/printing (04c7848)
Signature help and symbol rendering now suppress internal marker prefixes like \xFEtype and escape internal names more consistently, so anonymous/contextual types and synthetic symbols show cleaner user-facing labels. This fixes confusing output in signature help and node printing.
RemoteNode child traversal no longer double-visits arrays (f7acbad)
The native-preview RemoteNode.forEachChild logic was fixed so array children aren’t visited twice when a visitList callback is supplied. That prevents duplicate traversal in editor/API consumers and is covered by new async/sync tests.
