NOKIA releases naming rules

Hello Dears,

could you please explain for me the meaning of NOKIA's releases . for exemple RL10 , RL20 , FL17 ?

sometimes they add the letter A or SP , what is the rules of naming the releases at NOKIA ?


regards ,

example. FL18: FDD- LTE 2018
SP or anything after the year is a patch file after the initial release.

thanks you amadeo for your answer , it is very clear . what about RL20 ?

That is really old release, RL20 was probably released in 2011 or 2012. If that would have been written with the current naming than its probably FL11A or FL12.
