acct (6.6.4-6) unstable; urgency=medium

  The login accounting tool 'ac' is no longer effective on Debian systems
  since trixie because of the transition from recording system login records
  in /var/log/wtmp to the wtmpdb database. The tools in this package only
  understand login records in the utmp(5) format used for /var/log/wtmp and
  not wtmpdb databases. They can still be used for forensic purposes
  against files from systems that do store utmp-format logs.

  The process accounting capabilities of this package are still functional.

  It is recommended to install the 'wtmpdb' and 'libpam-wtmpdb' packages for
  login accounting on the running system.
