I have been running the website getlazarus.org for 13 years to support add features to both FPC and Lazarus that jump ahead of the normal releases. We have been working of dynamic packages for a long time, and there will be a period between now, and when it is sent as a MR back into the mainline. When enough time has passed and feedback given these features are typically rolled into the main release, and at getlazarus I move on towards developing the next features.
