Release Notes
*************
v2.2.5 released 2013-10-16
==========================
Percona Toolkit 2.2.5 has been released. This release has four new features and a number of bugfixes.
Query_time histogram has been added to the pt-query-digest JSON output, not the actual chart but the values necessary to render the chart later, so the values for each bucket.
As of pt-table-checksum 2.2.5, skipped chunks cause a non-zero exit status. An exit status of zero or 32 is equivalent to a zero exit status with skipped chunks in previous versions of the tool.
New --no-drop-triggers option has been implemented for pt-online-schema-change in case users want to rename the tables manually, when the load is low.
New --new-table-name option has been added to pt-online-schema-change which can be used to specify the temporary table name.
* Fixed bug #1199589: pt-archiver would delete the data even with the --dry-run option.
* Fixed bug #821692: pt-query-digest didn't distill LOAD DATA correctly.
* Fixed bug #984053: pt-query-digest didn't distill INSERT/REPLACE without INTO correctly.
* Fixed bug #1206677: pt-agent docs were referencing wrong web address.
* Fixed bug #1210537: pt-table-checksum --recursion-method=cluster would crash if no nodes were found.
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

v2.2.4 released 2013-07-18
==========================
Percona Toolkit 2.2.4 has been released. This release two new features and number of bugfixes.
Percona Toolkit 2.2.4 has been released. This release two new features and a number of bugfixes.
pt-query-digest --output json includes query examples as of v2.2.3. Some people might not want this because it exposes real data. New option, --output json-anon, has been implemented. This option will provide the same data without query examples. It's "anonymous" in the sense that there's no identifying data; nothing more than schema and table structs can be inferred from fingerprints.
