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! ​
