I'm working on some code I want to be compatible with multiple GHC versions and I'm trying to figure out which language extensions I can reasonably use. I definitely need usable fancy pattern synonyms (not the bare-bones ones in 7.8). So that should set a lower bound, but I don't remember where. 7.10? 8.0?
Looking at Git, if you need record syntax support in pattern synonyms, you will need to go with 8.0.
