0.4.0 - 2026-09-06

Release Notes

Added

• gpasswd, the fifteenth tool: it administers /etc/group and
  /etc/gshadow. A group administrator named in gshadow may add and remove
  members and set the group password without being root, which is why the tool
  is installed setuid; the superuser may additionally set the administrator and
  member lists with -A and -M. Contributed by @jlesage (#282)

Changed

• docs/PLATFORM-SUPPORT.md accounts for gpasswd in the three static-musl
  gaps: like newgrp it authenticates against the group password through
  crypt(3) rather than PAM, so it keeps working for a group administrator
  there; it resolves the caller through getpwuid_r, so it does not see
  directory users; and it can neither verify nor set a yescrypt group password
