The focus of this major release was to align 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 major release (4.7.5), Versioning and Access Control functionality underwent major refactorings. 294 JIRA issues were worked by fifteen developers over the last year 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.

Due to the significant 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 one of our a top priorities priority for the first quarter of 2019. Please see the outstanding issues section at the bottom of the release page for any known issues. |
