Drone code & PX4 update cycle

Is PX4 changing to a 6 month update cycle as mentioned in the drone code letter?

can you share the letter here please?

Dronecode is not just PX4 but a full drone software stack. Consequently PX4 will continue to have a ~8 weeks update cycle for main releases. Two of these releases will likely be aligned with the distribution releases for Dronecode.
