How can I create a mod specifically for version 1.20.1?

[AlexBrainhow]

I want to create a mod for minecraft version 1.20.1, and the example version is 1.20.6.
What do I need to change to have a different version, or where can I get an example for the version I need?

go to https://fabricmc.net/develop/ and pick 1.20.1, it will give you the up-to-date versions for your gradle.properties and the loom version for your build.gradle!
