@RkamilC to add the missing firmwares, how is the procedure you use? to contribute files? If you allow me the suggestion, instead of all the firmwares in the same folder, make more folders to classify, it would be easier to find what you want. Cameras, gimbals, flight controllers, for example and so we can check and those who have some saved same could collaborate.
@Peggy I have not checked, but I also have saved same versions, if you are looking for a specific one tell me, maybe I have it.
