We'd better to add which version each command started to be supported, e.g.

Command	Since Version
FCALL	2.7.0

This may not be a good first issue but actually the contributor should know detail about the command impl history :D

Contributors can write a string matching program to check if each command exists in a specific version of the source code.
So I think the contributor don't need to know detail about the command impl history

Hello, can you assign this issue to me?

@kay011 Thank you! As @jihuayu mentioned, maybe a quick way is to write a program to detect the support commands in each version.

@git-hulk Yeah！I plan to check the commands supported by each version through Python regular expressions. I will submit this script file and the final markdown file. This should be quick. Just paste the final results on the final docs.
