- parser no longer allows ',' after promiser or promisee. must be either ';' or lval
 - Make parser output in GCC compatible format the only supported format
   (remove --gcc-brief-format flag)
 - Silence license warnings in Enterprise Free25 installations
 - action_policy => "warn" causes not_kept classes to be set on promise needing repair.
 - command line option version (-V) now prints a shorter parsable version without graphic
 - implicit execution of server and common bundles taking arguments is skipped in cf-serverd.
 - WARNING: option --policy-server removed, require option to --bootstrap instead
 - process promises don't log if processes are out of range unless you
   run in verbose mode
 - reports promises are now allowed in any context (Redmine #2005)
 - cf-report has been removed
 - cf-execd: --once implies --no-fork
 - Version info removed from mail subject in the emails sent by cf-execd.
   The subject will only contain "[fqname/ipaddress]" instead of "communnity/nova [fqname/ipaddress]"
   Please change your email filters accordingly if necessary.
 - "outputs" promise type is retired. Their semantics was not clear, and the functionality
   is better suited for control body setting, not a promise.
 - Tokyo Cabinet databases are now automatically checked for
   correctness during opening. It should prevent a number of issues
   with corrupted TC databases causing binaries to hang.
 - Improved ACL handling on Windows, which led to some syntax changes. We now consistently
   use the term "default" to describe ACLs that can be inherited by child objects. These
   keywords have received new names:
       acl_directory_inherit -> acl_default
       specify_inherit_aces -> specify_default_aces
   The old keywords are deprecated, but still valid. In addition, a new keyword
       "acl_inherit" controls inheritance behavior on Windows. This feature does not exist on
       Unix platforms. (Redmine #1832)
