Native preview exposes more checker APIs (
1b81e8f)
The native-preview layer now exports NodeBuilderFlags and adds several new checker calls, including resolved signatures, widened/non-nullable/type-node conversion helpers, parameter type lookup, and an array-like type check. This broadens what tooling can query from the checker and makes the preview API substantially more capable.
Add a debug stack limit for tsgo entry points (2c25188)
TS_GO_DEBUG_STACK_LIMIT now lets developers cap goroutine stack size when the CLI and test entry points start up. That gives a controlled way to reproduce or prevent runaway stack growth during debugging.
Fix off-by-one truncation in union display (
ce43ebc)
Union type truncation now counts displayed elements correctly, so error text no longer under-reports how many union members were elided. This improves the accuracy of diagnostics and quick info for large unions.
JS Promise arity errors now point to the JSDoc-specific hint (
f65feaf)
In JS files, calling new Promise((resolve) => resolve()) now reports the dedicated TS2810 message telling users that new Promise() needs a JSDoc hint for a zero-arg resolve. This makes the diagnostic more actionable for checkJs users.
Reparse bracketed @param names as optional modifiers (5a31703)
Bracketed JSDoc parameter names are now always reparsed into ? optional markers, instead of being treated like plain optional declarations only in some cases. That fixes JS type inference and grammar behavior for defaulted parameters documented with [name] syntax.
Extension command renamed for version selection (56ab4af)
The built-in command for choosing a TypeScript version was renamed to the native-preview namespace and wired through the extension UI. This keeps the command surface aligned with the extension's naming scheme.
