Release Notes
*************
v2.1.1 released 2012-04-03
==========================
Percona Toolkit 2.1.1 has been released. This is the first release in the
new 2.1 series which supersedes the 2.0 series. We will continue to fix bugs
in 2.0, but 2.1 is now the focus of development.
2.1 introduces a lot of new code for:
* pt-online-schema-change (completely redesigned)
* pt-mysql-summary (completely redesigned)
* pt-summary (completely redesigned)
* pt-fingerprint (new tool)
* pt-table-usage (new tool)
There were also several bug fixes.
The redesigned tools are meant to replace their 2.0 counterparts because
the 2.1 versions have the same or more functionality and they are simpler
and more reliable. pt-online-schema-change was particularly enhanced to
be as safe as possible given that the tool is inherently risky.
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/).
