Dynamic import specifiers now get rewritten in CJS (
70c2f5e)
The CJS module transformer now visits the first argument to import(), so relative specifiers produced by expressions can be rewritten alongside static imports. This fixes a correctness gap in rewriteRelativeImportExtensions for dynamic imports in CommonJS output.
File rename avoids quadratic work on repeated unresolved imports (
1515af7)
GetEditsForFileRename now precomputes moved files and passes that context through import updating, avoiding rescanning every file once per duplicate unresolved import. That removes a pathological O(imports × files) slowdown on large projects.
Formatter is more robust on parser-recovered member lists (
19b6d56)
The formatter now treats error-bearing member list elements specially instead of trying to re-derive indentation from grammar-error nodes. This fixes a crash when formatting interfaces that contain recovered template literals or other malformed syntax.
Unknown tsconfig options regain spelling suggestions (e0e361b)
Unknown-option diagnostics now consult spelling suggestions and can emit a “did you mean” message for both command-line and config-file parsing. The change restores friendlier guidance for misspelled compiler options.
Top-level compiler options in tsconfig are reported explicitly (7a36206)
If a compiler option appears at the root of tsconfig.json instead of under compilerOptions, the parser now emits a dedicated diagnostic for it. That makes a common config mistake easier to spot and correct.
TS5092 source locations are preserved again (6a6b8f3)
The tsconfig parser now points TS5092 at the right location when the config root isn’t an object. This is a diagnostic-quality fix, but it improves the usefulness of the error significantly.
TS7059 is emitted for reserved type-assertion syntax in .mts/.cts (
f209df3)
The checker now reports the reserved-syntax diagnostic when type assertions appear in .mts or .cts files, matching the intended module-format restrictions. The updated baselines show the compiler now surfaces the additional errors in all affected scenarios.
AST layout was reorganized to remove duplicate fields (c3a0059)
The generated AST type definitions were reshuffled to separate declaration branding from other base interfaces and eliminate duplicated fields. This is a structural refactor that keeps the Go and preview AST models aligned, but it doesn’t appear to change user-facing behavior directly.
