Github user lvfangmin commented on the issue: https://github.com/apache/curator/pull/165 Thanks @cammckenzie for review, the TimerTrace is actually an internal helper class, it shouldn't have any backwards compatible problem. It is the TracerDriver that may have backwards compatible issue, but more strictly it's not a backwards compatible issue, it's that the users who are using TracerDriver have to change their implementation based on the new interface. @Randgalt can you help review on it, it's a feature required internally and we want to have it as soon as possible, thanks :)
