Maatkit version 6926 has been released: http://code.google.com/p/maatkit/

All sorts of fixes and enhancements were made in this month's release. mk-index-usage had two bug fixes and a new option, -- database (-D). A bug in mk-kill was fixed to keep it from killing slave replication threads in certain cases. Two new rules were added to mk-query-advisor (released last month), as well as two new options. One interesting feature new to mk-query-digest this month is that it now gets the error message from tcpdump events. A long- standing issue with mk-table-checksum and how it does or does not delete checksums was resolved, and it also got several new filtering options. And a bug was fixed in mk-variable-advisor (also released last month).
