Features

Improvements

SyntaxError reporting now aligns with other JS engines — file name is no longer embedded in the error message, but exposed via the stack property instead
Error.stack traces are now attached in error constructors, with ~100× performance improvement

nginx modules

Fixed expire field truncation in shared dict state files — millisecond timestamps were silently truncated to 10 digits, causing restored entries to appear expired on restart. Appeared in eca03622 (0.9.1)
Suppressed spurious slab log_nomem messages for evict-enabled shared dict zones, where allocation failures are expected behavior
Fixed stack trace reporting for ngx.fetch() exceptions in the QuickJS engine

Core

Fixed string offset map corruption in scope values hash — caused SEGV/SIGBUS crashes for multi-byte UTF-8 string constants >32 characters when accessing a character at index ≥ 32 (e.g. via .replace() or bracket notation). Regression since e7caa46d (0.9.5)
Fixed heap-buffer-overflow in atom hash triggered by Symbol()
Fixed WebCrypto importKey() crash with mismatched JWK key type
Fixed interactive mode detection for piped stdin. Regression since 4988565c (0.8.0)
Fixed build on macOS
Fixed PTR macro compatibility with newer BFD library
auto/cc: replaced which with portable command -v (thanks to Zurab Kvachadze)
