Unfortunately you will have to look in the sources to find out and for the hand written disectors that information may not be totally accurat. But the master branch should decode most of the current 3GPP spec for the more common protocols as Wireshark is used to verify products using those protocols. So if you are using a 5 year old Wireshark it would probably support specs from that year.

thanks for your reply. Sorry I don't know how to look into the sources. Is it safe that to assume that current version 3.4.2 support 3GPP release version from 2020 or 2019?

As an example 3GPP TS 38.413 V16.3.0 (2020-09)

If you use the GitLab search function to look at the repository you can see some useful info. Eg. with this search you can see all files that have "3GPP" and "TS" in them and then the git tag selector (by default showing "master") can be used to select different release tags (e.g. v3.4.2) to see what the code was for that version of Wireshark.
