We are proud to announce the release of Fedora 5.0.0.
| Info |
|---|
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 was to align 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:
- Linked Data Platform 1.0 - CRUD
- Web Access Control (as used by the Solid project) - Authorization
- Memento protocol (rfc7089) - Versioning
- Instance Digests in HTTP (rfc3230) - Binary Fixity
294 JIRA issues were worked by fifteen developers for this release on the core codebase alone. 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, and configuration settings. , and a new User's Guide focused on content modeling and metadata recommendations.
| Warning |
|---|
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. |
