Date: Sat, 28 Apr 2012 22:15:18 +0000
Subject: - Fixed an issue with the instance variable storage system never
 being initialised (since unknown revision) - Combined both string and integer
 instance variables into a single DBMap* structure - Fixed a missing new-line
 at the end of src/common/conf.h causing warnings
