Percona Playback 0.5 发布了，Percona Playback 是一个用来回放 MySQL 数据库负荷的工具。
该版本还是处于 Alpha 质量阶段，主要改进包括：
新特性:
Reports have been extended and now return the list of queries with a response time longer than the ones run on the original. Additional statistics, like the query types (SELECT, UPDATE,…) with the proportion off faster and slower statement for each categories, has been added as well.
Percona Playback now supports reading the slow query log from standard input (stdin) instead of log file.
For this release binary packages were prepared, full list is available in our documentation.
Bug 修复:
Multi-line queries in the slow query log didn’t work correctly. Bug fixed #1035217 (Stewart Smith).
Raw tcpdump format wasn’t documented. Bug fixed #1034527 (Hrvoje Matijakovic).
