  	have been updated when it was re-purposed to handle DSN
  	SUCCESS notifications. Problem reported by Sabahattin
  	Gucukoglu.  File: bounce/bounce_trace_service.c.
+ 
+ 20120202
+ 
+ 	Bugfix (introduced: Postfix 2.3): the "change header" milter
+ 	request could replace the wrong header. A long header name
+ 	could match a shorter one, because a length check was done
+ 	on the wrong string.  Reported by Vladimir Vassiliev.  File:
+ 	cleanup/cleanup_milter.c.
+ 
+ 20120214
+ 
+ 	Bugfix (introduced: Postfix 2.4): extraneous null assignment
+ 	caused core dump when postlog emitted the "usage" message.
+ 	Reported by Kant (fnord.hammer). File: postlog/postlog.c.
+ 
+ 20120217
+ 
+ 	Cleanup: missing #include statement for bugfix code added
+ 	20111226. File: local/unknown.c.
