Fedora 3.6 Release Notes
Release Date: July XX, 2012:
We are proud to announce the release of Fedora 3.6. Some of the notable new features include:
- *Migration to a modern Web Services framework. Fedora 3.6 incorporates work from the Google Summer of Code project to move from the aging Axis 1.3 library to Apache CXF. This allows Fedora to support MTOM, which provides a 33% size efficiency over Base64 encoded transmission.
- REST API Validation failure response codes changed to 400. If a REST API management operation results in a validation failure (e.g. ingest FOXML validation, validation failure via the DOObjectValidator module) the HTTP response code is now 400. Previously Fedora reported a generic Server Failure 500 response code. The response body indicates the nature of the validation error.
Acknowledgments
Many thanks to all of those who contributed to this release. In particular, thanks go to Jiri Kremser, a doctoral student at Masaryk University in the Czech Republic, for his work on the Google Summer of Code project.
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 offedora.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 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 |

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 |

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. |
