go RtcTokenBuilder vs rtctokenbuilder2

[seinshah]

What's the actual difference between rtc token builder version 1 and 2? I see that v2 allows for more granular config on the token, however, as I tested, the rtc token generated with v2 was no longer valid when clients used it for authentication. They got 110 : The authentication token for joining the rtc channel is wrong

The main questions are:

• Where can I read about the different between these two versions?
• When someone should use rtctokenbuilder2 instead of RtcTokenBuilder?
