Ports tree is unfrozen
Quoting Joe Marcus Clarke:
The ports tree has been unfrozen, and is now in the usual “slush” state
pending the releases of 6.4 and 7.1. This means no sweeping commits (or
commits which change a large number of files) until these releases are
announced. If you are in doubt as to whether or not a commit could be
considered sweeping, please ask portmgr.
A short description of what a sweeping commit is, can be seen on the portmgr webpage, or send us an email.
