[0.2.0] - 2026-08-27

Added

• Added the opt-in Linux beckon-signal-launcher, which pre-blocks an explicit signal allowlist before starting the JVM so signalfd can reliably receive external signals. USR2 and CHLD are rejected by default, and -Xrs is required for HotSpot-managed termination signals.
• Added Linux subprocess integration tests for launcher and no-launcher modes.

Fixed

• Linux registration now installs SIG_IGN only for signals in the launcher's pre-blocked external allowlist, preserving the registration race protection there while retaining SIG_DFL in default mode so externally-delivered signals are not silently swallowed.

[0.1.8] - 2026-08-17

Fixed

• Native call return codes (signal, kevent, kill, sigemptyset, sigaddset, pthread_sigmask, pthread_kill, and the signalfd mask update) are checked and throw with the return value and captured errno instead of being ignored.

[0.1.7] - 2026-07-16

Fixed

• Both signal backends (kqueue on macOS, signalfd on Linux) restore the previously-installed signal disposition on reset instead of forcing SIG_DFL.

Changed

• Updated the beckon dependency to 0.4.2.
