This update (released on Jan 21st) includes:
Bugfix:
-Correct the handling of quotes for identifiers in
ROLLBACK TO SAVEPOINT statements.
-Don't permit creation of dbs with same name as redo log file
(Bug #28867993).
-Use strncmp() instead of memcmp() for comparing logfile names
(prevent the uninitialized memory as result).
