v0.3.0

0.3.0

Breaking changes

• Compilation is native-only. The --dynamic option and embedded JavaScript execution runtime have been removed. Eligible dependencies compile natively by default; unsupported packages receive build diagnostics. QuickJS remains only in the native compiler's isolated comptime helper and as standalone regex/Unicode libraries.

Features

• process.constrainedMemory() and process.availableMemory() read the process's own cgroup limits, as Node.js does through libuv.

Performance

• Map and string lookups do less work. Absent string keys are rejected before the map is probed, and multi-byte substring searches no longer call memchr for every first-byte hit.
• Class property bags are read without being created.
• Runtime packs for Linux musl, Windows and WASI are much smaller. Their dev runtime objects no longer carry undefined-behavior checks, matching the glibc and macOS packs.

Fixes

• Native program objects use runtime ABI v14. The embedded JavaScript runtime's symbols were removed, so external object consumers must link the matching v0.3.0 runtime pack; the versioned marker rejects incompatible runtime objects at link time.
