v0.12.4

Added

sunsetr is now published on crates.io. Install or update it with cargo install sunsetr, alongside the AUR and Nix packages.

Fixed the time-until-next-transition countdown going stale after switching geo location or after a config change that only shifts timing.
Fixed automatic timezone detection on systems where /etc/localtime does not resolve under /usr/share/zoneinfo, such as NixOS.
Fixed clock transition times resolving incorrectly during the daylight-saving fall-back hour, when the local time repeats.
Fixed transition windows that cross local midnight being anchored to the wrong day.
Fixed preset state files being written non-atomically, which could leave a truncated file behind if a write was interrupted.
On first run, a geo.toml that cannot be parsed is now left untouched while the default config is created, extending the earlier fix that preserved readable coordinate files. (#55)
sunsetr stop now exits with a non-zero status when it fails, so scripts can detect an unsuccessful stop.
Fixed sunsetr status --follow not detecting when the sunsetr process closed the connection.
Configurations that leave no stable day or night period are now rejected with an error instead of producing a broken schedule.
Fixed clock-time config validation truncating HH:MM:SS times to whole minutes, which could wrongly reject a config with a sub-minute stable period, accept a night or day just under the one-hour minimum, or misreport a sub-minute window overlap as a missing stable period.
