AI summaryFixed a Windows-specific runtime crash in docs/examples/language/supported_features.ts.
Full changelog
Highlights
Patch release on top of v0.5.454 — fifth-round release-night fix. With v0.5.454's two skips landing, a third Windows-specific runtime bug surfaced: language/supported_features.ts exits with 0xC0000005 ACCESS_VIOLATION mid-execution after producing visibly corrupt output.
Fixes
- doc-tests windows-2022 —
docs/examples/language/supported_features.tsskipped on Windows. Same Windows-specific runtime divergence cluster as v0.5.454'sruntime/array_methods.tsandruntime/json_parse.ts— probably a single root cause (memory layout / NaN-boxing / GC on the Windows ABI) worth investigating at depth. Tracked as a single follow-up. Targeted skip via the// platforms:banner; the other 76 Windows doc-tests continue to pass.
