v2.0.3 released 2012-02-03

==========================

Percona Toolkit 2.0.3 has been released. The development team was very
8
busy last month making this release significant: two completely
9
redesigned and improved tools, pt-diskstats and pt-stalk, and 20 bug fixes.
11
Both pt-diskstats and pt-stalk were redesigned and rewritten from the ground
12
up. This allowed us to greatly improve these tools' functionality and
13
increase testing for them. The accuracy and output of pt-diskstats was
14
enhanced, and the tool was rewritten in Perl. pt-collect was removed and
15
its functionality was put into a new, enhanced pt-stalk. pt-stalk is now
16
designed to be a stable, long-running daemon on a variety of common platforms.
17
It is worth re-reading the documentation for each of these tools.
19
The 20 bug fixes cover a wide range of problems. The most important are
20
fixes to pt-table-checksum, pt-iostats, and pt-kill. Apart from pt-diskstats,
21
pt-stalk, and pt-collect (which was removed), no other tools were changed
22
in backwards-incompatible ways, so it is worth reviewing the full changelog
23
for this release and upgrading if you use any tools which had bug fixes.
25
Thank you to the many people who reported bugs and submitted patches.
