Maatkit version 7284 has been released: http://code.google.com/p/maatkit/

In this month's release, two tools receive a lot of enhancement, and two other tools are deprecated. These latter tools are mk-parallel- dump and mk-parallel-restore. As their PODs now indicate, "This tool is deprecated because after several complete redesigns, we concluded that Perl is the wrong technology for this task. ... It remains useful for some people who we know aren't depending on it in production, and therefore we are not removing it from the distribution."

Receiving the enhancements are mk-kill and mk-query-digest. Several options were added and removed from mk-kill, some bugs fixed, and the POD was updated with further explanations about how the tool works. A bug with mk-query-digest --interval was fixed, and two options were added: --variations and --run-time-mode. These options introduce helpful new functionality. --run-time-mode=event, for example, makes --run-time operate on "log time" (timestamps from the log) instead of wallclock time.
