　　Apache Curator 今天发布两个新版本，分别是 2.10.0 和 3.1.0 。
　　其中 2.10.0 改进内容：
　　
Bug

• 　　[CURATOR-208] - InterProcessSemaphoreV2 swallows InterruptedException
  
• 　　[CURATOR-209] - Background retry falls into infinite loop of reconnection after connection loss
  
• 　　[CURATOR-233] - Bug in double barrier
  
• 　　[CURATOR-244] - Creating parents with ACLProvider puts wrong ACLs on znodes
  
• 　　[CURATOR-278] - In transactions compressed option does not work with some fluent api combinations
  
• 　　[CURATOR-297] - Curator quickly starting+stopping a persistent ephemeral node causes dangling ephemeral node
  

Improvement

• 　　[CURATOR-279] - Semaphore Leases should return the node name
  
• 　　[CURATOR-294] - Optimize TreeCache, fix possible concurrency issue
  
• 　　[CURATOR-296] - Notify cache listeners when re-init completes after reconnect
  
• 　　[CURATOR-298] - Curator NodeCache.start() is blocking even with buildInitial=false
  

New Feature

• 　　[CURATOR-287] - PersistentEphemeralNode should be generalized to accept all create modes
  
• 　　[CURATOR-288] - Provide a mechanism to limit tree traversal in TreeCache + Return old values in NODE_REMOVED event
