Releases
OCUDU is an open-source initiative awarded initial funding by the National Spectrum Consortium (NSC) under a three-year programme running through October 2028. See the NSC announcement for details.
The first public release, v26.04, shipped in April 2026. The project follows a predictable bi-annual release cycle — new versions every April and October — to ensure steady feature development, community feedback integration, and long-term sustainability.

Roadmap
Planned features by release, through the end of the programme in October 2028.
The features shown are planned with allocated engineering resources and a defined delivery timeline, but this roadmap is not fixed. With additional engineering capacity and collaborative contributions, priorities and timelines can be adjusted. If there are features within the OCUDU scope that matter to you or your organisation and are not listed here, we welcome discussions on accelerating, expanding, or re-prioritising development through resource support and joint contribution.
