The most notable changes since version 1.4 are:
- The standalone Jackrabbit server component. The runnable
jackrabbit-standalone jar makes it very easy to start and run
Jackrabbit as a standalone server with WebDAV and RMI access.
- Search performance improvements. The performance of certain kinds
of hierarchical XPath queries has improved notably.
- Simple Google-style query language. The new GQL query syntax
makes it very easy to express simple full text queries.
- Transaction-safe versioning. Mixing transactions and versioning
operations has traditionally been troublesome in Jackrabbit.
This release contains a number of improvements in this area and
has specifically been reviewed against potential deadlock issues.
- Clustered workspace creation. A new workspace created in one
cluster node will now automatically appear also in the other
nodes of the cluster.
- SPI improvements. The SPI layer introduced in Jackrabbit 1.4
has seen a lot of improvements and bug fixes, and is shaping
up as a solid framework for implementing JCR connectors.
- Development preview: JSR 283 features. We have implemented
a number of new features defined in the public review draft of
JCR 2.0, created in JSR 283. These new features are accessible
through special "jsr283" interfaces in the Jackrabbit API. Note
however that none of these features are ready for production use,
and will be replaced with final JCR 2.0 versions in Jackrabbit 2.0.
See the release notes for all the details.
