Обсуждение: Another release note?

Is it worth mentioning this as a compatibility issue?

"Prior to PostgreSQL 7.3, serial  implied UNIQUE. This is no longer 
automatic. If you wish a serial column to be in a unique constraint or a 
primary key, it must now be specified, same as with any other data type."

And we did mention it in the 7.3 release notes:
    * serial columns are no longer automatically UNIQUE; thus, an index      will not automatically be created.
