Release Notes -- Apache Jackrabbit -- Version 2.0-beta6
Introduction
------------
This is a beta release of Apache Jackrabbit 2.0. This release is a fully compliant implementation of the JCR 2.0 API that was specified by the Java Specification Request 283 (JSR 283, http://jcp.org/en/jsr/detail?id=283).
However, the beta status of this release means that some parts of the implementation are not yet ready for normal production use.
Changes in this release
-----------------------
Jackrabbit 2.0 is a major upgrade from the earlier 1.x releases. The most notable changes in this release are:
* Upgrade to JCR 2.0. This Jackrabbit release implements and is based
on the official JCR 2.0 API. All of the features required by the
JSR 283 specification have been implemented.
* Upgrade to Java 5. All of Jackrabbit (except the jcr-tests component)
now requires Java 5 as the base platform. Java 1.4 environments are no
longer supported.
* Removal of deprecated classes and features. Jackrabbit 2.0 is not
backwards compatible with client code that used any classes or features
that had been deprecated during the 1.x release cycle.
* Separate JCR Commons components. Many of the general-purpose JCR
components like JCR-RMI and OCM are now developed and released
separately from the Jackrabbit content repository. See the individual
components for their most recent releases.
* Database connection pooling is now available for all database backends.
Non-pooled versions of the bundle persistence managers are still
available in the org.apache.jackrabbit.core.persistence.bundle package.
To enable connection pooling in an existing Jackrabbit repository,
replace the package name with org.apache.jackrabbit.core.persistence.pool
in your repository and workspace configuration files.
* Data store feature enabled in the default repository configuration.
* Full text indexing with Apache Tika. Jackrabbit can now extract and
index the full text content of many new types of documents, including
the Office Open XML files produced by Microsoft Office 2007 and higher.
* Apache Commons Collections, Apache Derby, Jetty, SLF4J and Apache Xerces
dependencies have been upgraded to more recent versions.
* OracleFileSystem class does not use special blob handling anymore as it
is not required for Oracle versions since 10R1. Use the Oracle9FileSystem
class if you need support for Oracle 9 or earlier.
