ZooKeeper 3.2.1 Release Notes
These release notes include new developer and user facing incompatibilities, features, and major improvements.
Note that there is a user visible semantic change to an existing API in the 3.2.0 release: ZOOKEEPER-444 "perms definition for PERMS_ALL differ in C and java", a bug fix which required a change to the JAVA definition of ALL to include ADMIN.
See 3.0 release notes and migration instructions if you are upgrading from version 2 of ZooKeeper (SourceForge) to version 3 or later.
