 	- fix: %doc wrongly inherits lang from last entry in %files.
 	- resurrect toplevel tar target.
 	- spec file removal separate from source removal (Shing-Gene Yung).
+	- add rpm prefix to MD5 routines to avoid name conflict on solaris.
 
 2.94 -> 2.95
 	- fix: last update transaction set segfault bug in installer.
