#16199: GHC 8.6 bundles libraries that don't correspond to Hackage releases -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: Component: libraries | Version: 8.6.3 (other) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #14678 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): We should be careful about `transformers`, since there are actually API- relevant code changes that were introduced in commit https://gitlab.haskell.org/ghc/packages/transformers/commit/80557845cdc0e72b.... In particular, I'm pretty sure that `contravariant-1.5` requires these changes to compile (at least, angerman reported an error when he tried to build `contravariant-1.5` with the Hackage version of `transformers-0.5.5.0`). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16199#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
