+* ==================== CORE CHANGES ===================
+
+
+* ==================== FIXED BUGS ====================
+
+The following bugs have been fixed or resolved. Note that "n-i-bz"
+stands for "not in bugzilla" -- that is, a bug that was reported to us
+but never got a bugzilla entry. We encourage you to file bugs in
+bugzilla (https://bugs.kde.org/enter_bug.cgi?product=valgrind) rather
+than mailing the developers (or mailing lists) directly -- bugs that
+are not entered into bugzilla tend to get forgotten about or ignored.
+
+
+To see details of a given bug, visit
+ https://bugs.kde.org/show_bug.cgi?id=XXXXXX
+where XXXXXX is the bug number as listed above.
