From Daniel Bernstein, Technical Lead and Developer, on behalf of the Fedora Committers

We are proud to announce the release of Fedora 5.0.0 December 14th, 2018.

The move from Fedora 3.x to 4.x represented a full reimplementation of the Fedora architecture.

The move from Fedora 4.x to 5.x DOES NOT represent the same scope of change. The changes between Fedora 4.7.5 and 5.0.0 are relatively small, although they represent non-backwards compatible breaking changes due to API and data model differences.

As of the 5.0.0 release, the Fedora project is conforming to standard Semantic Versioning. See the Fedora Semantic Versioning policy for details.

The focus of this major release is alignment of the Fedora codebase with the Fedora API Specification.  While the code behind basic CRUD (Create, Retrieve, Update, and Delete) changed only incrementally from the previous release (4.7.5),  Versioning and Access Control functionality underwent major refactorings. Per the Fedora API Specification, this release of the Fedora application implements the following underlying specifications:

294 JIRA issues were worked by fifteen developers for this release.  In addition, we also developed the Fedora API Test Suite which can be run against this release to verify compliance with the aforementioned specification.  Finally, the documentation underwent a full overhaul with special attention to the modifications to the API changes, additions, deletions, deprecations, configuration settings, and a new User’s Guide focused on content modeling and metadata recommendations.

Due to the changes to existing APIs and data models, Fedora 5.0.0 is not backwards compatible.  The Fedora Import Export Utility does not currently support upgrading data from Fedora 4 to Fedora 5. However adding upgrade support this utility is a top priority for the first quarter of 2019. Please see the outstanding issues section at the bottom of the release page for any known issues.


The following features are still in this release, but have been flagged for future removal.
