Forum OpenACS Q&A: Re: Canonical source for Oracle and Postgres AOLserver drivers?

Looking at the CVS logs, I think the current state is as below. From oldest to newest, with differences from the next older version:
  1. Version in OpenACS AOLserver distribution
  2. Version in acs-pg repository - Improved error messages thanks to Steve Woodcock, Added patches by David Walker
  3. Version in OpenACS.org repository - DanW removed debug output for bind variables
  4. Version in SourceForge repository - The code cleanup Jeff described
Is there any reason why the older versions aren't updated to the SourceForge version? Or, are there any reasons not to remove the older versions, leaving a note telling people where to find the newest?
