How stable is the V2 API

Is the V1 API deprecated? I am just getting started w zitadel and I see some posts about the v1 and v2, also features flags related to that. Since I am just starting out I rather not deal with any unstable behaviour, is it fine to go along with the v1 for now as it's probably more mature? (I see a lot of v2 issues in this discord thread, so somewhat confused)
