hpack

Changes in 0.36.0

• Don’t infer Paths_-module with spec-version: 0.36.0 or later

Changes in 0.35.5

• Add (undocumented) list command

Changes in 0.35.4

• Add --canonical, which can be used to produce canonical output instead of trying to produce minimal diffs
• Avoid unnecessary writes on --force (see #555)
• When an existing .cabal does not align fields then do not align fields in the generated .cabal file.
• Fix a bug related to git conflict markers in existing .cabal files: When a .cabal file was essentially unchanged, but contained git conflict markers then hpack did not write a new .cabal file at all. To address this hpack now unconditionally writes a new .cabal file when the existing .cabal file contains any git conflict markers.

Changes in 0.33.0

• Support GHC 8.8.1: fail is no longer a part of Monad. Instead, it lives in the MonadFail class. Adapting our code to this change meant changing the types of exporting functions, unfortunately, hence the major version bump.

• Warn on duplicate fields (see #283)

• Extend build-tools so that it subsumes Cabal’s build-tools and build-tool-depends (see #254)
• Add support for system-build-tools

• Add missing extra-source-files (see #302)

Changes in 0.29.1

Changes in 0.26.0

• Major refactoring of the exposed API (much cleaner now, but lot’s of breaking changes!)
