Release Notes
*************
v2.1.4 released 2012-09-20
==========================
Percona Toolkit 2.1.4 has been released. This release includes 26 bug fixes and three new features: Making pt-table-checksum work with Percona XtraDB Cluster, adding a --run-time option to pt-table-checksum, and implementing the "Version Check" feature, enabled through the --version-check switch. For further information on --version-check, see http://www.mysqlperformanceblog.com/2012/09/10/introducing-the-version-check-feature-in-percona-toolkit/. The bug fixes are widely assorted. The following highlights some of the more interesting and "hot" bugs:
* Fixed bug 1017626: pt-table-checksum doesn't work with Percona XtraDB Cluster
Note that this requires Percona XtraDB Cluster 5.5.27-23.6 or newer, as the fix depends on this bug https://bugs.launchpad.net/codership-mysql/+bug/1023911 being resolved.
* Fixed bug 1034170: pt-table-checksum --defaults-file isn't used for slaves
Previously, users had no recourse but using --recursion-method in conjunction with a dsn table to sidestep this bug, so this fix is a huge usability gain. This was caused by the toolkit not copying the -F portion of the main dsn.
* Fixed bug 1039184: pt-upgrade error "I need a right_sth argument"
Which were stopping pt-upgrade from working on a MySQL 4.1 host.
* Fixed bug 1036747: pt-table-sync priv checks need to be removed
The same checks were removed in the previous release from pt-table-checksum, so this continues the trend.
* Fixed bug 1038995: pt-stalk --notify-by-email fails
This was a bug in our shell option parsing library, and would potentially affect any option starting with 'no'.
Like 2.1.3, this is another solid bug fix release, and 2.1 users are encouraged to upgrade.
Percona Toolkit packages can be downloaded from http://www.percona.com/downloads/percona-toolkit/ or the Percona Software Repositories (http://www.percona.com/software/repositories/).
