- <h3>Change in Binary Delta serialization</h3>
- <p>
- Versioning information is added to the binary serialization streams in a backward compatible manner.
- In addition, this release includes a <a href="https://issues.apache.org/jira/browse/UIMA-4743">bug fix</a>
- that changes the format of Binary Delta serialization slightly, but only for delta serialization, as used by
- UIMA-AS.  UIMA-AS next release will include support for this and 
- automatically select the old or new version when sending a delta CAS back to the client; so this change
- should be invisible to users.
