Release notes: - Official FreeBSD binaries are now available http://docs.haskellstack.org/en/stable/install_and_upgrade/#freebsd ( #1253 https://github.com/commercialhaskell/stack/issues/1253). Major changes: - Extensible custom snapshots implemented. These allow you to define snapshots which extend other snapshots. See #863 https://github.com/commercialhaskell/stack/issues/863. Local file custom snapshots can now be safely updated without changing their name. Remote custom snapshots should still be treated as immutable. Behavior changes: - stack path --compiler was added in the last release, to yield a path to the compiler. Unfortunately, --compiler is a global option that is useful to use with stack path. The same functionality is now provided by stack path --compiler-exe. See #2123 https://github.com/commercialhaskell/stack/issues/2123 - For packages specified in terms of a git or hg repo, the hash used in the location has changed. This means that existing downloads from older stack versions won’t be used. This is a side-effect of the fix to #2133 https://github.com/commercialhaskell/stack/issues/2133 - stack upgrade no longer pays attention to local stack.yaml files, just the global config and CLI options. #1392 https://github.com/commercialhaskell/stack/issues/1392 - stack ghci now uses :add instead of :load, making it potentially work better with user scripts. See #1888 https://github.com/commercialhaskell/stack/issues/1888 Other enhancements: - Grab Cabal files via Git SHA to avoid regressions from Hackage revisions #2070 https://github.com/commercialhaskell/stack/pull/2070 - Custom snapshots now support ghc-options. - Package git repos are now re-used rather than re-cloned. See #1620 https://github.com/commercialhaskell/stack/issues/1620 - DESTDIR is filtered from environment when installing GHC. See #1460 https://github.com/commercialhaskell/stack/issues/1460 - stack haddock now supports --hadock-arguments. See #2144 https://github.com/commercialhaskell/stack/issues/2144 - Signing: warn if GPG_TTY is not set as per man gpg-agent Bug fixes: - Now ignore project config when doing stack init or stack new. See #2110 https://github.com/commercialhaskell/stack/issues/2110 - Packages specified by git repo can now have submodules. See #2133 https://github.com/commercialhaskell/stack/issues/2133 - Fix of hackage index fetch retry. See re-opening of #1418 https://github.com/commercialhaskell/stack/issues/1418#issuecomment-21763384... - HPack now picks up changes to filesystem other than package.yaml. See #2051 https://github.com/commercialhaskell/stack/issues/2051 - “stack solver” no longer suggests —omit-packages. See #2031 https://github.com/commercialhaskell/stack/issues/2031 - Fixed an issue with building Cabal’s Setup.hs. See #1356 https://github.com/commercialhaskell/stack/issues/1356 - Package dirtiness now pays attention to deleted files. See #1841 https://github.com/commercialhaskell/stack/issues/1841 - stack ghci now uses extra-lib-dirs and extra-include-dirs. See #1656 https://github.com/commercialhaskell/stack/issues/1656 - Relative paths outside of source dir added via qAddDependentFile are now checked for dirtiness. See #1982 https://github.com/commercialhaskell/stack/issues/1982 - Signing: always use --with-fingerprints ------------------------------ Thanks to all our contributors for this release: - Benno Fünfstück @bennofs https://github.com/bennofs - Emanuel Borsboom @borsboom https://github.com/borsboom - Levi Notik @levinotik https://github.com/levinotik - Michael Sloan @mgsloan https://github.com/mgsloan - Michael Snoyman @snoyberg https://github.com/snoyberg - Oleg Grenrus @phadej https://github.com/phadej - Sebastian Graf @sgraf812 https://github.com/sgraf812 - Simon Jakobi @sjakobi https://github.com/sjakobi - Tim Dysinger @dysinger https://github.com/dysinger - Yann Esposito @yogsototh https://github.com/yogsototh - Yuji Yamamoto @igrep https://github.com/igrep And thanks also to the 150+ contributors to past releases!
