Release Notes for ModeShape 3.0.0.Beta1
The ModeShape 3.0.0.Beta1 release is the first beta release of our new architecture, and is suitable
only for testing and previewing features. APIs and storage formats are still subject to change.
What's new
3.0.0.Beta1 is the first 3.x release that provides a feature complete implementation of the
JCR 2.0 (JSR-283) specification. This release adds support for full-text search, text extraction,
and shareable nodes, plus it fixes quite a few bugs and issues. We've also improved the way
binary values (and related information such as MIME types and extract text) are handled and
stored within the BinaryStore.
Overall, ModeShape 3.0 has changed a lot since ModeShape 2.8.x:
- ModeShape now uses Infinispan for all caching and storage, giving a powerful and flexible
foundation for creating JCR repositories that are fast, scalable, and highly available.
Infinispan offers a great deal of storage options (via cache loaders), but can also be used
as a distributed, mulit-site, in-memory data grid.
- Improved performance. ModeShape 3 is just plain seriously fast, and performance is all-around
faster than 2.x - most operations are at least one if not several orders of magnitude faster!
We'll publish performance and benchmarking results closer to the final release.
- Improved scalability. ModeShape 3 has been designed to store and access the content so that
a node can have hundreds of thousands of nodes (even with same-name-siblings) yet still be
incredibly fast. Additionally, repositories can scale to millions of nodes and be deployed
across many processes. (Clustering is not yet supported in this release.)
- Improved configuration. There is no more global configuration of the engine; instead,
each repository is configured with a separate JSON file, which must conform to a JSON Schema
and can be validated by ModeShape prior to use. Repository configurations can even be
changed while the repository is running (some restrictions apply), making it possible to
add/change/remove sequencers, authorization providers, and many other configuration options
while the repository is in use.
- Each repository can be deployed, started, stopped, and undeployed while the engine and other
repositories are still in use.
- Sessions now immediately see all changes persisted/committed by other sessions, although
transient changes of the session always take precedence.
- Support for participation in JTA and XA transactions, allowing (container-managed or bean-managed)
EJBs and JCR clients that programmatically use XA transactions to commit the changes in the transactions.
- New monitoring API that allows accessing the history for over a dozen metrics.
- New sequencing API, so sequencers now use the JCR API to get at the content being processed
and create/update the derived content. Sequencers can also dynamically register namespaces and
node types. Now it's easy to create custom sequencers.
- Simplified API for implementing custom MIME type detectors. ModeShape still has built-in
detectors that use the filename extensions and the binary content.
- New and simpler API for implementing custom text extractors.
- Improved storage of binary values of all sizes, with a separate facility for storing these on the file
system. Storage of binary values in Infinispan and DBMSes will be added in upcoming releases.
- API interfaces and methods that were deprecated in 2.7.0.Final (or later) have been removed.
There weren't many of these; most of the ModeShape API remains the same.
- Integration with JBoss AS 7.1. ModeShape runs as an integrated subsystem within AS7, and
the AS7 tooling can be used to define and manage repositories independently of each other
while the server is running.
- Local and remote JDBC drivers for issuing JCR-SQL2 queries and getting database metadata via the JDBC API
- Many bug fixes and minor improvements
Features
Most of the JCR features previously supported in 2.x are working and ready for testing.
If any issues are found, please log a bug report in our JIRA.

A few features not related to the JCR 2.0 API have been planned and are still not yet
implemented. The most important one is enabling a repository to access the content in
external systems (e.g., file system, SVN, JDBC, JCR, etc.). This most likely will be pushed
to 3.1 so that we can focus on releasing 3.0 with full support for JCR 2.0.
