Here are the recent changes to the packaging guidelines.
Many changes have been made to the Ruby packaging guidelines to reflect
the current state of Ruby packaging.
Note that the macros required for some of those guidelines might still
be making their way into the stable releases.
The Libraries and Applications section of the guidelines was modified to
favor independent packaging of applications and to discourage separate
graphical applications from having dependencies on each other.
An exception allowing the use of a specific subdirectory in /etc/opt by
Chrome native messaging extensions was approved.
