ModeShape &version; includes several new features, improvements, and bug fixes since 2.6.0.Final:

- improved memory usage during export and indexing

- JPA connector's background garbage collection can be disabled
- JPA no longer caches large value entities
- fixed race condition in RepositoryConnectionPool
- added public API methods to register node types in CND files, eliminating need for depending upon implementation classes
- deprecated public API interfaces/methods that were redundant with JCR 2.0
- added support for setting values with custom javax.jcr.Binary implementations
- added public API methods to get the SHA-1 hash of binary values
- fixes to query processing
- fixes to enable building on Windows
- corrected Teiid sequencers generation of transformation queries
- upgraded to Tika 1.0
- upgraded versions of several Maven plugins


## JCR Supported Features

**ModeShape implements all of the required JCR 2.0 features** (repository acquisition, 
authentication, reading/navigating, query, export, node type discovery, and permissions and capability 
checking) and **most of the optional JCR 2.0 features** (writing, import, observation, workspace management
versioning, locking, node type management, same-name siblings, shareable nodes, and orderable 
child nodes). The remaining optional features in JCR 2.0 (access control management, 
lifecycle management, retention and hold, and transactions) may be introduced in future versions.

ModeShape supports the [JCR-SQL2][1] and [JCR-QOM][2] query languages defined in [JSR-283][3], plus the [XPath][4] and 
[JCR-SQL][5] languages defined in [JSR-170][6] but deprecated in JSR-283. ModeShape also supports a simple
[search-engine-like language][7] that is actually just the [full-text search expression grammar][8] 
used in the second parameter of the CONTAINS(...) function of the JCR-SQL2 language.

The &version; release has not yet been certified to be fully compliant with JCR 2.0. The ModeShape 
project plans to focus on attaining this certification in the very near future.

## Connectors, Sequencers, and Other Features

As with previous releases, ModeShape &version; integrates with [JAAS][9], [web application security][10],
or you can easily [integrate it with other systems][11]. ModeShape can use a variety of back-ends to store 
information ([RDBMSes][12], [Infinispan data grid][13], [disk-storage][25] [memory][14], [JBoss Cache][15], [JCR repositories][16]), can access content
in multiple systems ([file systems][17], [SVN repositories][18], [JDBC metadata][19]), can [federate][20] multiple stores and
systems into a single JCR repository, or can access other systems using [custom connectors][21].
ModeShape is also able to automatically extract and store useful content from files you upload into 
the repository using its library of [sequencers][22], making that information much more accessible and 
searchable than if it remains locked up inside the stored files. And ModeShape provides
[WebDAV and RESTful services][23] to allow various clients to access the content. For details, see the [Reference Guide][24].
