Release Notes
*************
v2.1.9 released 2013-02-11
==========================
Percona Toolkit 2.1.9 has been released. This is the first maintenance release
of the 2.1 series, and primarily aims to restore backwards-compatibility with
releases 2.1.7 and older.
* Fixed bug 1103221: pt-heartbeat 2.1.8 doesn't use precision/sub-second timestamps
* Fixed bug 1099665: pt-heartbeat 2.1.8 reports big time drift with UTC_TIMESTAMP
The previous release switched the time authority from Perl to MySQL, and from
local time to UTC. Unfortunately, these changes caused a loss of precision and,
if mixing versions of pt-heartbeat, made the tool report a huge amount
of replication lag.
This release makes the tool compatible with the 2.1.7 and older releases again,
but makes the UTC behaviour available through the --utc option.
* Fixed bug 1099933: pt-stalk is too verbose, fills up log
This adds a --verbose option to pt-stalk, which is useful if using the tool as a daemon.
All users are recommended to upgrade, but in particular, users of versions 2.1.7 and
older are strongly recommended to skip 2.1.8 and go directly for 2.1.9.
Users of pt-heartbeat in 2.1.8, who prefer the UTC behavior, should keep in mind that they
will have to use the --utc option after upgrading.
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/).
