C3P0 0.9.5.2 发布，此版本改进内容如下：
-- Fix a bug in MLog bridge to slf4j logging, in which loggability of levels of wrapped loggers
was misreported, leading to useless allocation of log Strings below the logging threshold. Grr.
[change is in mchange-commons-java 0.2.11]. Many thanks to Lewis Wong on Stack Exchange for calling
attention to this issue.
-- Embed last acquistion failure as nested Exception in CannotAcquireResourceException. Thanks to
nigam on github for this addition.

C3P0是一个开放源代码的JDBC连接池，Hibernate的发行包中默认使用此连接池。据说性能最好。
