Hi, I can't supply a diff at the moment (because I've already ghc-8.8.2 and 60 bumped or updated ports on my machine), but I'd like to see an update of games/hedgewars if possible. The current version 0.99.22) depends on devel/hs-dataenc, which doesn't build with ghc-8.2.2 and is EOL anyways. hedgewars-0.99.23 seems to use devel/hs-sandi instead of devel/hs-dataenc, so this would probably work with what we already have in ports and what we'll have in ports after the update to ghc-8.2.2. It also now depends on devel/hs-regex-tdfa which we also already have in the tree.
Ciao, Kili
