v2.2.2 released 2013-04-24

==========================
7
Percona Toolkit 2.2.2 has been released. This is the second release of
8
the 2.2 series and aims to fix bugs in the previous release and provide
9
usability enhacements to the toolkit.
11
Users may note the revival of the --show-all option in pt-query-digest.
12
This had been removed in 2.2.1, but resulted in too much output in
15
A new --recursion-method was added to pt-table-checksum: cluster. This
16
method attempts to auto-discover cluster nodes, alleviating the need to
17
specify cluster node DSNs in a DSN table (--recursion-method=dsn).
19
The following highlights some of the more interesting and "hot" bugs in
22
* Bug #1127450: pt-archiver --bulk-insert may corrupt data
24
pt-archiver --bulk-insert didn't work with --charset UTF-8. This revealed
25
a case where the tool could corrupt data by double-encoding. This is now
26
fixed, but remains relatively dangerous if using DBD::mysql 3.0007 which
27
does not handle UTF-8 properly.
29
* Bug #1163372: pt-heartbeat --utc --check always returns 0
31
Unfortunately, the relatively new --utc option for pt-heart was still
32
broken because "[MySQL] interprets date as a value in the current time zone
33
and converts it to an internal value in UTC." Now the tool works correctly
34
with --utc by specifying "SET time_zone='+0:00'", and older versions of
35
the tool can be made to work by specifying --set-vars "time_zone='+0:00'".
37
* Bug #821502: Some tools don't have --help or --version
39
pt-align, pt-mext, pt-pmp and pt-sift now have both options.
41
This is another solid bug fix release, and all users are encouraged to upgrade.
