Gemini system development has moved to this new framework and a faster governance process is required to be able to submit work to the programme backlog ready for planning in future Programme Increments (PIs).

Currently there is only one Change Proposal (CP) in the Gemini Regulatory programme (CP5455) - Gemini Autumn Release 22. Work on this is due to complete in November 2022. Once it has completed there will be no active Change Proposal against which work can be booked.
