Hello,

The distribution doesn’t contain the Java SE library because nowadays automatic dependency management systems as Maven, Gradle or Ant+Ivy are much better alternatives to manual management.

The README file in the distribution folder DOCS-SDKs/sdk_client_java_se/lib explains how to configure the major build tools to import the Java SE client library.

In the CHANGELOG of the server you can find the list of released versions with notes about compatibility, bugfixes and enhancements.
