v0.1.7

0.1.7

Features

• Development builds support native source debugging. --optimization=dev adds TypeScript and JavaScript source locations across the C and LLVM backends, with source-named variables in LLVM builds.
• More Math operations compile statically. Additional constants and methods include hyperbolic functions, clz32, fround, imul, expm1, and log1p.
• Static Promise handling supports rejection callbacks. Promise.prototype.then accepts both fulfillment and optional rejection handlers, including returned promises.
• Static compilation accepts more package layouts. Installed entries can compile their own TypeScript and JavaScript imports, and CommonJS packages with safe export prologues remain eligible for static compilation.
• Fixed tuple spreads compile in tuple literals. Const tuple inference is preserved when checked with satisfies.
• Dynamic globalThis exposes Node host globals. Escaping through the global object initializes the same Node globals used by embedded modules.

Performance

• Async and generator fibers commit stack memory on demand. They retain their existing stack capacity while using less committed memory.
• Development builds compute compiler fingerprints faster. Parallel fingerprint reads preserve the existing cache identity and invalidation behavior.

Fixes

• Caught and rejected values preserve JavaScript object classification. Native exception handling distinguishes objects from primitive values across catch and promise paths.
• TypeScript project settings and Node declarations are preserved. Built-in default imports honor effective project options, and RequestInfo remains available across imported sources.
• Optional chains and dynamic option records retain supported values. Array callbacks inside optional chains, narrowed optional receivers, and records containing abort handles compile correctly.
• Compiler analysis handles more edge cases safely. Deep or shared type graphs no longer overwhelm diagnostics, and property names spelled arguments are not treated as reads of the special binding.
