Tdlib-purple doesn't work with latest so-called stable td, i.e. since they assign long-term/stable/user numbering but don't officially release it rather than current/development/testing numbering, there's apparently no way to find such correct version to downgrade, either (update: I found 1.7.9 and installed tdlib-purple, but GitHub is difficult for casual testers.)
