v0.6.0 — “Joulu“

The code name for this release is “Joulu”, which is Finnish for “Christmas” 🎅🏼

Added

• New denv utility, inspired by daemontools' envdir, which may be used to manipulate the environment before executing a chained child process.

Fixed

• Retry system calls that may return with errno set to EINTR when interrupted by signals to indicate they can be restarted from user space.
• Remove leftover, useless $E format specifier when reporting errors during daemonization.

Changed

• The project is now built in C23 mode by default. In practice -std=c2x gets used to cover systems which may have slightly older compilers.
