Yes, that is the plan. Xenomai 3.3 is going to be the first release fully implementing the CXP. Xenomai 4 which is going to use a different real-time core will be developed in parallel to Xenomai 3.3, aiming at CXP-compliance too. It should be clear that March 31, 2021 is the date for completing the CXP specification, not that of any release implementing it, which can only happen later by definition. > I also concern about that how long Xenomai-3.3 will be live?

How long a particular Xenomai release is maintained for a particular kernel version currently depends on a few individuals and companies having a specific requirement to keep such port alive, and contributing to this task directly (doing the work) or indirectly (funding someone else's work). Although there is a commitment to run Xenomai 3.x on top of kernel v5.10 asap, I'm not aware of any formal commitment of any current contributor to maintain this port for a pre-defined period of time. One may only assume that by picking a LTS kernel like v5.10, we are likely going to maintain it "for some time". -- Philippe.
