Fedora 3.5 Release Notes

Release Date: August 18, 2011:

We are proud to announce the release of Fedora 3.5. Although a minor release, this version includes a number of exciting new features and bug fixes that make Fedora an ever more compelling repository platform.

You are encouraged to download this new release and give it a spin. Please let us have your comments and feedback via the mailing lists, and of course please let us know of any problems you discover.

Some of the important new features are:

Spring-based configuration. Fedora has adopted Spring as a means of configuring its internal components. This move to a modern, enterprise-grade framework offers greater flexibility for integrating repository components, and allows Fedora to more easily adapt to challenging deployment environments. While fedora.fcfg is considered deprecated as of this release, due to time constraints some module configuration has not yet been moved out of fedora.fcfg and into native spring xml. See also Spring Configuration in the documentation.
Standard WAR file distribution. Fedora runtime configuration has moved entirely outside of the WAR file, allowing a single standardized war file to be included in each release. This allows bugfix releases to be distributed and applied in a much simpler fashion than before: merely replace the old WAR file with the updated one.
FeSL policy enforcement improvements. Numerous enhancements have been made to FeSL authZ. Notably, the requirement of installing dbxml has been removed. This had been a barrier to FeSL testing and adoption. With the various improvements in FeSL authZ, we consider this feature "beta" and encourage users of Fedora to give it a try and provide feedback.
FEDORA_HOME environment variable no longer required to run fedora server. Outside of running commandline utilities, FEDORA_HOME is now ignored, and has been completely replaced with more flexible means of specifying the location of the fedora home directory.
JSON support for RISearch Resource index searches now support JSON, allowing greater ease of use with javascript clients.
DC datastream fixes. The DC datastream, with contains information needed for the internal functioning of Fedora, is now more robust. If a user inadvertently removes the necessary dc:identifier fields, this will be automatically corrected.
Build and testing improvements. Numerous testing and development improvements are part of 3.5. Perhaps most notably, deployment and running of a live Fedora instance can now be managed automatically as part of a standard maven build.

Tomcat Compatibility

Tomcat 5.5 and earlier are no longer supported. This release has been extensively tested with Tomcat 6.0.x, and is also known to work with Tomcat 7.0.x

REST API

As part of ongoing cleanup efforts, REST API responses have been fixed so that they are now fully compliant with their declared schema. This means that some responses might be slightly different when compared to those from earlier releases. For more information, see the overarching issue in Jira

Tomcat memory leak detection

Starting with Tomcat 6.0.24 (the bundled version of Tomcat included in this release is 6.0.29), Tomcat logs messages to indicate potential memory leaks. You may notice a number of SEVERE messages logged when Tomcat is stopped as a consequence of this new Tomcat behavior. FCREPO-969 has been logged to track these and address these where they lie within Fedora code.

For a detailed list of features and bugfixes comprising this release see the tables below.
