The Hibernate team is proud to announce the first candidate release for 5.0. The main changes since the Beta2 release include:
- Initial generic typing for Hibernate native (Session, e.g.) APIs
- Continued development of the new bytecode enhancement capabilities including improved support in the Maven and Gradle plugins
- Support for parameterized types with AttributeConverter implementations
- Improved OSGi integration testing using Pax Exam and Karaf, and publishing a hibernate-osgi Karaf features file
- Auto quoting of keywords used as identifiers (
- Incorporating fixes, improvements and suggestions to the improved schema update and validation tooling
A lot of help from the community went into this release and the previous Beta releases. Thanks for all the help and work and testing and doggedness!
As always, see http://hibernate.org/orm/downloads/ for information on obtaining the releases.
Report any issues to Hibernate Jira
I have just finished releasing Hibernate O/RM 5.0.0.Beta2. Beyond Beta1, this release adds:
- Support for Spatial/GIS data through importing Hibernate Spatial.
- Complete redesign of
bulk id tablesused to support update/delete queries against multi-table structures. The redesign helps better fit what different databases support.
- Redesign of transaction management
- Much improved (and still improving!) schema management tooling for export, validation and migration.
At this point, 5.0.0 is getting a lot of testing. So even though it is still in Beta I am feeling pretty confident of its quality. I opted for another Beta here instead of CR1 for a few reasons:
- Investigate whether we want to convert Hibernate's native APIs (Session, etc) to be typed. There is one especially tricky case that needs to be figured out. A major release like this would be the time to do that
- I have just introduced some pretty significant Transaction changes since Beta1. I felt it would be prudent to have one more Beta to allow people time to try out those changes and allow for additional changes based on feedback
- I would still like to complete deprecating the Settings contract. The last piece there is the discussion I started earlier on the dev list wrt its usage in SPI contracts (L2 cache, etc). This effects a few integrations.
- I am working on better Karaf support for hibernate-osgi. Specifically creating a Karaf features respository that users can simply pick up and use. That work is well under way, but ongoing.
As always, see http://hibernate.org/orm/downloads/ for information on obtaining Hibernate O/RM.
We just got done releasing Hibernate O/RM 5.0.0.Beta1. I will follow up later with a more in depth blog post for 5.0.0.Final, but this first Beta implements all new APIs and most new features. Specifically in this Beta include:
- New bootstrapping API - better determinism, better integration
- Java 8 Support (though still compatible with Java 6). Just add hibernate-java8 to your classpath.
- Ability to handle additional Java types for id attributes marked as GenerationType#AUTO. Built-in support for Number and UUID. Expandable via new org.hibernate.boot.model.IdGeneratorStrategyInterpreter extension
- scanning support for non-JPA usage
- NamingStrategy has been removed in favor of a better designed API. 2 actually: org.hibernate.boot.model.naming.ImplicitNamingStrategy and org.hibernate.boot.model.naming.PhysicalNamingStrategy
Additionally, support for AttributeConverters has been expanded and more fully realized:
- fully supported for non-@Enumerated enum values
- applicable in conjunction with @Nationalized support
- called to handle null values
- settable in hbm.xml by using type="converter:fully.qualified.AttributeConverterName"
- integrated with hibernate-envers
- collection values, map keys
See http://hibernate.org/orm/downloads/ for information on obtaining Hibernate ORM.
NOTE: 5.0 is expected to be compatible with Java 6 (aside from the hibernate-java8 module naturally). However, Beta1 will not work with Java 6 due to something with JAXB that I have not yet had time to investigate. Beta1 requires Java 7. Again, the expectation is to have it be compatible with Java 6 by the next release if possible.
I have just released 4.3.1.Final, the first bugfix release for Hibernate ORM 4.3. In addition to bug fixes, a few improvements of note include:
- HHH-5289 : Improved performance of reflection calls
- HHH-6911 : Allows reading and writing @DiscriminatorValue from/to @DiscriminatorColumn when combined with InheritanceType.JOINED (for portability with providers which need DiscriminatorColumn)
- HHH-8865 : Added a new guide on logging to the growing set of topical guides. This is the first know documentation of any sort on using/configuring JBoss Logging, and also discusses some of the more good-to-know specific logging categories. See http://docs.jboss.org/hibernate/orm/4.3/topical/html/logging/Logging.html
See the release page for details of all changes.
Artifacts can be found in the usual places.
The Hibernate team is proud to announce the Hibernate ORM 4.3.0.Final Release. With this release, Hibernate is now a certified implementation of the JPA 2.1 specification. Certified awesomeness!
A lot of work has gone into this release over the last few months. The main focus of 4.3 was JPA 2.1 support, so much of the work these past few months focused on new JPA 2.1 features. The new features defined for JPA 2.1 include:
- Support for stored procedures. See my previous blog for details
- CriteriaUpdate and CriteriaDelete allow definition and execution of UPDATE and DELETE queries in type-safe Criteria form.
- Entity listeners can now take advantage of dependency injection through CDI.
- AttributeConverters, which define the ability to apply conversions on basic values between their database representation and their representation in your domain model. This is similar in concept to Hibernate's Type contract, although certainly less powerful (can only apply to basic values and operate on in-memory values). On the positive side, JPA AttributeConverters are portable across providers.
- Entity Graph support
- Standardized schema generation. With 2.1 JPA now defines schema generation which is standardized across providers in terms of how generation is performed and the settings providers understand as a baseline. Arun Gupta has a good write up of the basic schema generation support.
- Synchronization of persistence contexts via SynchronizationType
- @ConstructorResult support in result set mappings for native queries
The significant non-JPA work that has gone into 4.3 includes:
- Continued improvement in Hibernate's support for OSGi environments. OSGi support in 4.3 is still somewhat bound by certain design limitations within Hibernate, We plan to fully address these limitations in 5.0 (see HHH-8501 for details).
- Continued work on new bytecode enhancement support within Hibernate, adding support for
inline dirty checking. See HHH-8354 for details.
- Initial break down of the monolithic DocBook-based manuals into smaller Asciidoc-based topical guides (HHH-8606). This is an ongoing process.
