  • Added support for reproducible builds using the SOURCE_DATE_EPOCH environment variable. See https://reproducible-builds.org/docs/source-date-epoch/ for more information.
  • Extban $Q of type acting has been implemented. This extban prevents matching users from using the KICK command.

  • Fixed issue where WHO nick on invisible clients (user mode i) wouldn't work
