Many of the changes in 5.2.0 have important ramifications in terms of both usage and extension. Be sure to read the 5.2 Migration Guide for details.
Below is a discussion of the major changes.
Java 8 baseline
5.2 moves to Java 8 as its baseline. This means:
The hibernate-java8 module has been removed, and that functionality has been moved into hibernate-core.
Native support for Java 8 date/time types as Query parameters.
Support for streaming (java.util.stream.Stream) query results.
Support for java.util.Optional as return from methods that may return null.
Leveraging Java 8 "default methods" when introducing new methods to extension points.
Consolidating JPA support into hibernate-core.
That effectively means that the hibernate-entitymanager module no longer exists. Its functionality being consumed into hibernate-core.
JCache support
Support for using any JCache-compliant cache impl as a second-level caching provider.
Session-level batch size support
Support has been added for specifying a batch size for write operations per Session.
5th bug-fix release for 5.0
The 5th bug-fix release for Hibernate ORM 5.0. This release and the upcoming 5.0.6 release have been done on an accelerated time-box of 2 weeks (from the normal 4 weeks for bug-fix releases) due to US holidays.
The complete list of changes can be found here (or here for people without a Hibernate Jira account).
For information on consuming the release via your favorite dependency-management-capable build tool, see http://hibernate.org/orm/downloads/
For those of you allergic to dependency-management-capable build tools, the release bundles can be obtained from SourceForge or BinTray.
Fourth bug-fix release for 5.0
The fourth bug-fix release for Hibernate ORM 5.0
There are 52 issues resolved in this release. 20 of those came out of the recent Jira cleanup. Initially that initiative pulled in roughly 750 issues. To date, 66 of those have been resolved - fixed or verified as out-of-date, unable-to-reproduce, etc. An additional 14 have been more properly reclassified as feature or enhancement requests rather than bugs. The really cool part is the amount of community help we have gotten in making that happen! Thanks to everyone responding, verifying and even fixing alot of these bugs!
The complete list of changes can be found here. People without a Hibernate Jira account will not be able to access the previous link and can access the changelog in GitHub; the issue I reported with Atlassian has been resolved and is ready for deployment into our hosted environment, I just do not know when that will happen.
