RCS 5.8 is available

GNU RCS (Revision Control System) 5.8 is available.  RCS is a set of programs to manage multiple revisions of files.  RCS can store, retrieve, log, identify, and merge revisions.  It is useful for files that are revised frequently, e.g., programs, documentation, graphics, and papers.  You can download it from:

Here are the changes since 5.7:

    • Dropped configure option: --with-diffutils
    • Configuration more strict in some ways, more lax in others.
    • New configure option: --enable-suid[=setreuid]
    • New configure option: --disable-mmap
    • New configure option: --enable-mailer=PROG
    • New configure option: --enable-compat2
    • You can "make check" prior to "make install".
  • Bug fixes
    • Remove all edit info when removing all revisions.
    • Code no longer uses mktemp(3).
    • Misc manpage tweaks / fixes.
  • Other changes
    • All commands accept ‘--help’ and ‘--version’.
    • A string of all digits is now valid for author, state.
    • Env var RCS_MEM_LIMIT controls stdio threshold.
    • RCS can now work with files larger than 2 gigabytes.
    • Pass-through for RCS file ‘commitid SYMBOL’ now builtin.
    • RCS file top-level grammar frozen.
    • RCS file syntax-validated earlier, completely.
    • Possible to specify an empty log message with ci -m, rcs -m.
    • Date option accepts some more date-only formats
    • Changes to rcsdiff
      • New handling for option: -U N
      • Refined "same-revision don't call diff" optimization

  • Keith Thompson
  • Klaus T. Aehlig
  • Ludovic Courtès
  • Mike Mestnik
  • Nelson H. F. Beebe
  • Paul Eggert
  • Ralf Wildenhues
