Release Notes
*************
v2.2.2 released 2013-04-19
==========================
Percona Toolkit 2.2.2 has been released. This is the second release
of the 2.2 series, and aims to fix bugs in the previous release and
provide usability enhacements to the toolkit.
Users may note the revival of the --show-all option in
pt-query-digest. This had been removed in 2.2.1, but resulted in
the tool's output bloating considerably.
Meanwhile, pt-table-checksum got a usability enhancement, in the form
of --recursion-method=cluster, which will attempt to autodiscover
cluster nodes, alleviating the need to specify a dsns table.
The following highlights some of the more interesting and "hot" bugs
in this release:
* Bug #1127450: pt-archiver --charset and --bulk-insert fail, may corrupt data
pt-archiver --bulk-insert didn't work with --charset UTF-8. This
revealed a case where the toolkit could corrupt data. This should
now be fixed, but like other UTF-8-related operations, remains
relatively dangerous if using DBD::mysql 3.0007.
* Bug #1163372: pt-heartbeat --utc --check always returns 0
This makes --check and --utc useful. Older releases may be able to
work around this issue by calling the tool with --set-vars "time_zone='+0:00'"
* Bug #821502: Some tools don't have --help or --version
pt-align, pt-mext, pt-pmp and pt-sift now have both options.
This is another solid bug fix release, and all 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/).
