See haskellstack.org for installation and upgrade instructions. Major changes: - Some notable changes in stack init: - Overall it should now be able to initialize almost all existing cabal packages out of the box as long as the package itself is consistently defined. - Choose the best possible snapshot and add extra dependencies on top of a snapshot resolver rather than a compiler resolver - #1583 https://github.com/commercialhaskell/stack/pull/1583 - Automatically omit a package (--omit-packages) when it is compiler incompatible or when there are packages with conflicting dependency requirements - #1674 https://github.com/commercialhaskell/stack/pull/1674. - Some more changes for a better user experience. Please refer to the doc guide for details. - Add support for hpack, alternative package description format #1679 https://github.com/commercialhaskell/stack/issues/1679 Other enhancements: - Docker: pass ~/.ssh and SSH auth socket into container, so that git repos work #1358 https://github.com/commercialhaskell/stack/issues/1358 . - Docker: strip suffix from docker —version. #1653 https://github.com/commercialhaskell/stack/issues/1653 - Docker: pass USER and PWD environment bariables into container. - On each run, stack will test the stack root directory (~/.stack), and the project and package work directories (.stack-work) for whether they are owned by the current user and abort if they are not. This precaution can be disabled with the --allow-different-user flag or allow-different-user option in the global config (~/.stack/config.yaml). #471 https://github.com/commercialhaskell/stack/issues/471 - Added stack clean --full option for full working dir cleanup. - YAML config: support Zip archives. - Redownload build plan if parsing fails #1702 https://github.com/commercialhaskell/stack/issues/1702. - Give mustache templates access to a ‘year’ tag #1716 https://github.com/commercialhaskell/stack/pull/1716. - Have “stack ghci” warn about module name aliasing. - Add “stack ghci —load-local-deps”. - Build Setup.hs with -rtsopts #1687 https://github.com/commercialhaskell/stack/issues/1687. - stack init accepts a list of directories. - Add flag infos to DependencyPlanFailures (for better error output in case of flags) #713 https://github.com/commercialhaskell/stack/issues/713 - stack new --bare complains for overwrites, and add --force option #1597 https://github.com/commercialhaskell/stack/issues/1597. Bug fixes: - Previously, stack ghci would fail with cannot satisfy -package-id when the implicit build step changes the package key of some dependency. - Fix: Building with ghcjs: “ghc-pkg: Prelude.chr: bad argument: 2980338” #1665 https://github.com/commercialhaskell/stack/issues/1665. - Fix running test / bench with --profile / --trace. - Fix: build progress counter is no longer visible #1685 https://github.com/commercialhaskell/stack/issues/1685. - Use “-RTS” w/ profiling to allow extra args #1772 https://github.com/commercialhaskell/stack/issues/1772. - Fix withUnpackedTarball7z to find name of srcDir after unpacking (fixes stack setup fails for ghcjs project on windows) #1774 https://github.com/commercialhaskell/stack/issues/1774. - Add space before auto-generated bench opts (makes profiling options work uniformly for applications and benchmark suites) #1771 https://github.com/commercialhaskell/stack/issues/1771. - Don’t try to find plugin if it resembles flag. - Setup.hs changes cause package dirtiness #1711 https://github.com/commercialhaskell/stack/issues/1711. - Send “stack templates” output to stdout #1792 https://github.com/commercialhaskell/stack/issues/1792. ------------------------------ Thanks to all our contributors for this release: - Aaron Wolf @wolftune https://github.com/wolftune - Artem Chernyak @achernyak https://github.com/achernyak - Dan Aloni @da-x https://github.com/da-x - Daniel Gasienica @gasi https://github.com/gasi - Emanuel Borsboom @borsboom https://github.com/borsboom - Erik Stevenson @narrative https://github.com/narrative - Gauthier Segay @smoothdeveloper https://github.com/smoothdeveloper - Greg Weber @gregwebs https://github.com/gregwebs - Grégoire Détrez @gdetrez https://github.com/gdetrez - Harendra Kumar @harendra-kumar https://github.com/harendra-kumar - Mark Karpov @mrkkrp https://github.com/mrkkrp - Martin Kolinek - Matt Gambogi @gambogi https://github.com/gambogi - Michael Sloan @mgsloan https://github.com/mgsloan - Michael Snoyman @snoyberg https://github.com/snoyberg - Oleg Grenrus @phadej https://github.com/phadej - Eldar Yakupov @panamiga https://github.com/panamiga - Prayag Verma @pra85 https://github.com/pra85 - Simon Hengel @sol https://github.com/sol - Simon Jakobi @sjakobi https://github.com/sjakobi - Tristan Webb @drwebb https://github.com/drwebb - Yves Parès @YPares https://github.com/YPares And thanks also to the 150+ contributors to past releases!
