Percona is gladto announce the release of Percona Toolkit 2.2.4on July 17th, 2013

新特性：
New Features:

• 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. Before this feature was implemented this information wasn’t     available.
  

修复的Bugs：
Bugs Fixed:

• pt-table-checksum would fail if     variable explicit_defaults_for_timestamp was enabled in     MySQL 5.6. Bug fixed #1163735.
  
• Trying to assign 0     to any variable by using --set-vars option would cause     “Invalid --set-vars value” message. Bug fixed     #1182856.
  
• Fixed the typo in the pt-online-schema-change     code that could lead to a tool crash when copying the rows. Bug fixed #1188264
  
• pt-table-checksum was using the first     non-unique index instead of the one with the highest cardinality due to a     sorting bug. Bug fixed #1199591
