Only configurable via config-file for the time being. - (!) commandline interface is reworked slightly to support multiple inputs/outputs (`brittany --write-mode=inplace *.hs`). This removes the --input/--output flags. - Ensure compatibility with stackage - Change default global config path (old configs are still respected) - Improve support for per-project config - Fix several bugs and Improve language extension support full changelog at https://hackage.haskell.org/package/brittany-0.9.0.0/changelog brittany was recently added to stackage, and should hopefully be included in the next LTS release. -- lennart
