Changelog for cabal-install-

-*-change-log-*- Mikhail Glushenkov <> August 2017 * Removed the '--root-cmd' parameter of the 'install' command (#3356). * Deprecated 'cabal install --global' (#3356). * Changed 'cabal upload' to upload a package candidate by default (#3419). Same applies to uploading documentation. * Added a new 'cabal upload' flag '--publish' for publishing a package on Hackage instead of uploading a candidate (#3419). * Added optional solver output visualisation support via the tracetree package. Mainly intended for debugging (#3410). * Removed the '--check' option from 'cabal upload' (#1823). It was replaced by package candidates. * Fixed various behaviour differences between network transports (#3429). * The bootstrap script now works correctly when run from a Git clone (#3439). * Removed the top-down solver (#3598). * The '-v/--verbosity' option no longer affects GHC verbosity (except in the case of '-v0'). Use '--ghc-options=-v' to enable verbose GHC output (#3540, #3671). * Changed the default logfile template from '.../$pkgid.log' to '.../$compiler/$libname.log' (#3807). * Added a new command, 'cabal reconfigure', which re-runs 'configure' with the most recently used flags (#2214). * Added add the '--index-state' flag for requesting a specific version of the package index (#3893, #4115). * Support for building Backpack packages. See for more details. * Support the Nix package manager (#3651). * Made the 'template-haskell' package non-upgradable again (#4185). * Fixed password echoing on MinTTY (#4128). * Added a new solver flag, '--install-base-libraries', that allows any package to be installed or upgraded (#4209). * New 'cabal-install' command: 'outdated', for listing outdated version bounds in a .cabal file or a freeze file (#4207). * Added qualified constraints for setup dependencies. For example, --constraint=" == 1.0" constrains all setup dependencies on bar, and --constraint=" == 1.0" constrains foo's setup dependency on bar (part of #3502). * Non-qualified constraints, such as --constraint="bar == 1.0", now only apply to top-level dependencies. They don't constrain setup or build-tool dependencies. The new syntax --constraint=" == 1.0" constrains all uses of bar. * Added a technical preview version of the 'cabal doctest' command (#4480). Ryan Thomas <> March 2016 * If there are multiple remote repos, 'cabal update' now updates them in parallel (#2503). * New 'cabal upload' option '-P'/'--password-command' for reading Hackage password from arbitrary program output (#2506). * Better warning for 'cabal run' (#2510). * 'cabal init' now warns if the chosen package name is already registered in the source package index (#2436). * New 'cabal install' option: '--offline' (#2578). * Accept 'builddir' field in cabal.config (#2484) * Read 'builddir' option from 'CABAL_BUILDDIR' environment variable. * Remote repos may now be configured to use https URLs. This uses either curl or wget or, on Windows, PowerShell, under the hood (#2687). * Install target URLs can now use https e.g. 'cabal install'. * Automatically use https for cabal upload for the main (other repos will use whatever they are configured to use). * Support for dependencies of custom Setup.hs scripts (see * 'cabal' program itself now can be used as an external setup method. This fixes an issue when Cabal version mismatch caused unnecessary reconfigures (#2633). * Improved error message for unsatisfiable package constraints (#2727). * Fixed a space leak in 'cabal update' (#2826). * 'cabal exec' and 'sandbox hc-pkg' now use the configured compiler (#2859). * New 'cabal haddock' option: '--for-hackage' (#2852). * Added a warning when the solver cannot find a dependency (#2853). * New 'cabal upload' option: '--doc': upload documentation to hackage (#2890). * Improved error handling for 'sandbox delete-source' (#2943). * Solver support for extension and language flavours (#2873). * Support for secure repos using hackage-security (#2983). * Added a log file message similar to one printed by 'make' when building in another directory (#2642). * Added new subcommand 'init' to 'cabal user-config'. This subcommand creates a cabal configuration file in either the default location or as specified by --config-file (#2553). * The man page for 'cabal-install' is now automatically generated (#2877). * The '--allow-newer' option now works as expected when specified multiple times (#2588). * New config file field: 'extra-framework-dirs' (extra locations to find OS X frameworks in). Can be also specified as an argument for 'install' and 'configure' commands (#3158). * It's now possible to limit the scope of '--allow-newer' to single packages in the install plan (#2756). * Full '--allow-newer' syntax is now supported in the config file (that is, 'allow-newer: base, ghc-prim, some-package:vector') (#3171). * Improved performance of '--reorder-goals' (#3208). * Fixed space leaks in modular solver (#2916, #2914). * Made the solver aware of pkg-config constraints (#3023). * Added a new command: 'gen-bounds' (#3223). See * Tech preview of new nix-style isolated project-based builds. Currently provides the commands (new-)build/repl/configure. Johan Tibell <> January 2015 * New command: user-config (#2159). * Implement 'cabal repl --only' (#2016). * Fix an issue when 'cabal repl' was doing unnecessary compilation (#1715). * Prompt the user to specify source directory in 'cabal init' (#1989). * Remove the self-upgrade check (#2090). * Don't redownload already downloaded packages when bootstrapping (#2133). * Support sandboxes in '' (#2137). * Install profiling and shared libs by default in '' (#2009).
