 Release Notes
 *************
 
+v2.2.4 released 2013-07-17
+==========================
+
+Percona Toolkit 2.2.4 has been released. This release two new features and 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. 
+
+When using drop swap with pt-online-schema-change there is some production impact. This impact can be measured because tool outputs the current timestamp on lines for operations that may take awhile.
+
+* Fixed bug #1163735: pt-table-checksum fails if explicit_defaults_for_timestamp is enabled in 5.6
+pt-table-checksum would fail if variable explicit_defaults_for_timestamp was enabled in MySQL 5.6.
+
+* Fixed bug #1182856: Zero values causes "Invalid --set-vars value: var=0"
+Trying to assign 0 to any variable by using --set-vars option would cause “Invalid --set-vars value” message. 
+
+* Fixed bug #1188264: pt-online-schema-change error copying rows: Undefined subroutine &pt_online_schema_change::get
+Fixed the typo in the pt-online-schema-change code that could lead to a tool crash when copying the rows.
+
+* Fixed bug #1199591: pt-table-checksum doesn't use non-unique index with highest cardinality
+pt-table-checksum was using the first non-unique index instead of the one with the highest cardinality due to a sorting bug.
+
+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
