# 3.0.1.0 [Herbert Valerio Riedel](mailto:hvr@gnu.org) April 2020
  * Add GHC-8.8 flags to `normaliseGhcFlags`
    ([#6379](https://github.com/haskell/cabal/pull/6379)).

# 3.0.0.0 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) August 2019
  * The 3.0 migration guide gives advice on adapting Custom setup
    scripts to backwards-incompatible changes in this release:
    https://github.com/haskell/cabal/wiki/3.0-migration-guide.
  * Due to [#5119](https://github.com/haskell/cabal/issues/5119), the
    `cabal check` warning for bounds on internal libraries has been
    disabled.
  * Introduce set notation for `^>=` and `==` operators
    ([#5906](https://github.com/haskell/cabal/pull/5906)).
  * 'check' reports warnings for various ghc-\*-options fields separately
    ([#5342](https://github.com/haskell/cabal/issues/5432)).
  * `KnownExtension`: added new extensions `DerivingVia` and
    `EmptyDataDeriving`.
  * Add `extra-dynamic-library-flavours`, to specify extra dynamic library
    flavours to build and install from a .cabal file.
  * `autoconfUserHooks` now passes `--host=$HOST` when cross-compiling
  * Introduce multiple public libraries feature
    ([#5526](https://github.com/haskell/cabal/pull/5526)).
    * New build-depends syntax
    * Add a set of library components to the `Dependency` datatype
    * New `visibility` field in the `library` stanza
    * New `LibraryVisibility` field in `InstalledPackageInfo`
    * New syntax for the `--dependency` Cabal flag
  * Static linking
    * Add `--enable-executable-static` flag for building fully
      static executables (GHC's normal "statish" linking links
      Haskell libraries statically, but libc and system dependencies
      dynamically). This new flag links everything statically.
    * Note you likely want to link against `musl` or another libc that
      supports fully static linking;
      [`glibc` has some issues](https://sourceware.org/glibc/wiki/FAQ#Even_statically_linked_programs_need_some_shared_libraries_which_is_not_acceptable_for_me.__What_can_I_do.3F)
      with fully static linking.
  * Fix corrupted config file header for non-ASCII package names
    ([2557](https://github.com/haskell/cabal/issues/2557)).
  * Extend `Distribution.Simple.Utils.rewriteFileEx` from ASCII to UTF-8 encoding.
  * Change the arguments of `Newtype` class to better suit @DeriveAnyClass@ usage,
    add default implementation in terms of `coerce` / `unsafeCoerce`.
  * Implement support for response file arguments to defaultMain* and cabal-install.
  * Uniformly provide 'Semigroup' instances for `base < 4.9` via `semigroups` package
  * Implement `{cmm,asm}-{sources,options} buildinfo fields for
    separate compilation of C-- and ASM source files (#6033).
  * Setting `debug-info` now implies `library-stripping: False` and
    `executable-stripping: False) ([#2702](https://github.com/haskell/cabal/issues/2702))
  * `Setup.hs copy` and `install` now work in the presence of
    `data-files` that use `**` syntax
    ([#6125](https://github.com/haskell/cabal/issues/6125)).

----

### 2.4.1.1 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) December 2018

  * Fix `--with-compiler` failing to locate compiler on Windows
    ([#5753](https://github.com/haskell/cabal/pull/5753)).
  * Cabal can once again be built with GHC 7.8 and 7.6
    ([#5730](https://github.com/haskell/cabal/pull/5730)).

### 2.4.1.0 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) November 2018

  * Warnings in autogenerated files are now silenced
    ([#5678](https://github.com/haskell/cabal/pull/5678)).
  * Improved recompilation avoidance, especially when using GHC 8.6
    ([#5589](https://github.com/haskell/cabal/pull/5589)).
  * Do not error on empty packagedbs in `getInstalledPackages`
    ([#5516](https://github.com/haskell/cabal/issues/5516)).


### 2.4.0.1 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) September 2018

  * Allow arguments to be passed to `Setup.hs haddock` for `build-type:configure`
    ([#5503](https://github.com/haskell/cabal/issues/5503)).

# 2.4.0.0 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) September 2018
  * Due to [#5119](https://github.com/haskell/cabal/issues/5119), the
    `cabal check` warning for bounds on internal libraries has been
    disabled.
  * `Distribution.Simple.Haddock` now checks to ensure that it
    does not erroneously call Haddock with no target modules.
    ([#5232](https://github.com/haskell/cabal/issues/5232),
    [#5459](https://github.com/haskell/cabal/issues/5459)).
  * Add `getting` (less general than `to`) Lens combinator,
    `non`) and an optics to access the modules in a component
    of a `PackageDescription` by the `ComponentName`:
    `componentBuildInfo` and `componentModules`
  * Linker `ld-options` are now passed to GHC as `-optl` options
    ([#4925](https://github.com/haskell/cabal/pull/4925)).
  * Add `readGhcEnvironmentFile` to parse GHC environment files.
  * Drop support for GHC 7.4, since it is out of our support window
    (and has been for over a year!)
  * Deprecate `preSDist`, `sDistHook`, and `postSDist` in service of
    `new-sdist`, since they violate key invariants of the new-build
    ecosystem. Use `autogen-modules` and `build-tool-depends` instead.
    ([#5389](https://github.com/haskell/cabal/pull/5389)).
  * Added `--repl-options` flag to `Setup repl` used to pass flags to the
    underlying repl without affecting the `LocalBuildInfo`
    ([#4247](https://github.com/haskell/cabal/issues/4247),
    [#5287](https://github.com/haskell/cabal/pull/5287))
  * `KnownExtension`: added new extensions `BlockArguments`
    ([#5101](https://github.com/haskell/cabal/issues/5101)),
    `NumericUnderscores`
    ([#5130]((https://github.com/haskell/cabal/issues/5130)),
    `QuantifiedConstraints`, and `StarIsType`.
  * `buildDepends` is removed from `PackageDescription`. It had long been
    uselessly hanging about as top-level build-depends already got put
    into per-component condition trees anyway. Now it's finally been put
    out of its misery
    ([#4383](https://github.com/haskell/cabal/issues/4283)).
  * Added `Eta` to `CompilerFlavor` and to known compilers.
  * `cabal haddock` now generates per-component documentation
    ([#5226](https://github.com/haskell/cabal/issues/5226)).
  * Wildcard improvements:
    * Allow `**` wildcards in `data-files`, `extra-source-files` and
      `extra-doc-files`. These allow a limited form of recursive
      matching, and require `cabal-version: 2.4`.
      ([#5284](https://github.com/haskell/cabal/issues/5284),
      [#3178](https://github.com/haskell/cabal/issues/3178), et al.)
    * With `cabal-version: 2.4`, when matching a wildcard, the
      requirement for the full extension to match exactly has been
      loosened. Instead, if the wildcard's extension is a suffix of the
      file's extension, the file will be selected. For example,
      previously `foo.en.html` would not match `*.html`, and
      `foo.solaris.tar.gz` would not match `*.tar.gz`, but now both
      do. This may lead to files unexpectedly being included by `sdist`;
      please audit your package descriptions if you rely on this
      behaviour to keep sensitive data out of distributed packages
      ([#5372](https://github.com/haskell/cabal/pull/5372),
      [#784](https://github.com/haskell/cabal/issues/784),
      [#5057](https://github.com/haskell/cabal/issues/5057)).
    * Wildcard syntax errors (misplaced `*`, etc), wildcards that
      refer to missing directories, and wildcards that do not match
      anything are now all detected by `cabal check`.
    * Wildcard ('globbing') functions have been moved from
      `Distribution.Simple.Utils` to `Distribution.Simple.Glob` and
      have been refactored.
  * Fixed `cxx-options` and `cxx-sources` buildinfo fields for
    separate compilation of C++ source files to correctly build and link
    non-library components ([#5309](https://github.com/haskell/cabal/issues/5309)).
  * Reduced warnings generated by hsc2hs and c2hs when `cxx-options` field
    is present in a component.
  * `cabal check` now warns if `-j` is used in `ghc-options` in a Cabal
    file. ([#5277](https://github.com/haskell/cabal/issues/5277))
  * `install-includes` now works as expected with foreign libraries
    ([#5302](https://github.com/haskell/cabal/issues/5299)).
  * Removed support for JHC.
  * Options listed in `ghc-options`, `cc-options`, `ld-options`,
    `cxx-options`, `cpp-options` are not deduplicated anymore
    ([#4449](https://github.com/haskell/cabal/issues/4449)).
  * Deprecated `cabal hscolour` in favour of `cabal haddock --hyperlink-source` ([#5236](https://github.com/haskell/cabal/pull/5236/)).
  * Recognize `powerpc64le` as architecture PPC64.
  * Cabal now deduplicates more `-I` and `-L` and flags to avoid `E2BIG`
    ([#5356](https://github.com/haskell/cabal/issues/5356)).
  * With `build-type: configure`, avoid using backslashes to delimit
    path components on Windows and warn about other unsafe characters
    in the path to the source directory on all platforms
    ([#5386](https://github.com/haskell/cabal/issues/5386)).
  * `Distribution.PackageDescription.Check.checkPackageFiles` now
    accepts a `Verbosity` argument.
  * Added a parameter to
    `Distribution.Backpack.ConfiguredComponent.toConfiguredComponent` in order to fix
    [#5409](https://github.com/haskell/cabal/issues/5409).
  * Partially silence `abi-depends` warnings
    ([#5465](https://github.com/haskell/cabal/issues/5465)).
  * Foreign libraries are now linked against the threaded RTS when the
    'ghc-options: -threaded' flag is used
    ([#5431](https://github.com/haskell/cabal/pull/5431)).
  * Pass command line arguments to `hsc2hs` using response files when possible
    ([#3122](https://github.com/haskell/cabal/issues/3122)).

----

## 2.2.0.1 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) March 2018

  * Fix `checkPackageFiles` for relative directories ([#5206](https://github.com/haskell/cabal/issues/5206))


# 2.2.0.0 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) March 2018

  * The 2.2 migration guide gives advice on adapting Custom setup
    scripts to backwards-incompatible changes in this release:
    https://github.com/haskell/cabal/wiki/2.2-migration-guide.
  * New Parsec-based parser for `.cabal` files is now the
    default. This brings memory consumption and speed improvements, as
    well as making new syntax extensions easier to implement.
  * Support for common stanzas (#4751).
  * Added elif-conditionals to `.cabal` syntax (#4750).
  * The package license information can now be specified using the
    SPDX syntax. This requires setting `cabal-version` to 2.2+ (#2547,
    #5050).
  * Support for GHC's numeric -g debug levels (#4673).
  * Compilation with section splitting is now supported via the
    `--enable-split-sections` flag (#4819)
  * Fields with mandatory commas (e.g. build-depends) may now have a
    leading or a trailing comma (either one, not both) (#4953)
  * Added `virtual-modules` field, to allow modules that are not built
    but registered (#4875).
  * Use better defaulting for `build-type`; rename `PackageDescription`'s
    `buildType` field to `buildTypeRaw` and introduce new `buildType`
    function (#4958)
  * `D.T.PackageDescription.allBuildInfo` now returns all build infos, not
    only for buildable components (#5087).
  * Removed `UnknownBuildType` constructor from `BuildType` (#5003).
  * Added `HexFloatLiterals` to `KnownExtension`.
  * Cabal will no longer try to build an empty set of `inputModules`
    (#4890).
  * `copyComponent` and `installIncludeFiles` will now look for
    include headers in the build directory (`dist/build/...` by
    default) as well (#4866).
  * Added `cxx-options` and `cxx-sources` buildinfo fields for
    separate compilation of C++ source files (#3700).
  * Removed unused `--allow-newer`/`--allow-older` support from
    `Setup configure` (#4527).
  * Changed `FlagAssignment` to be an opaque `newtype` (#4849).
  * Changed `rawSystemStdInOut` to use proper type to represent
    binary and textual data; new `Distribution.Utils.IOData` module;
    removed obsolete `startsWithBOM`, `fileHasBOM`, `fromUTF8`,
    and `toUTF8` functions; add new `toUTF8BS`/`toUTF8LBS`
    encoding functions. (#4666)
  * Added a `cabal check` warning when the `.cabal` file name does
    not match package name (#4592).
  * The `ar` program now receives its arguments via a response file
    (`@file`).  Old behaviour can be restored with
    `--disable-response-files` argument to `configure` or
    `install` (#4596).
  * Added `.Lens` modules, with optics for package description data
    types (#4701).
  * Support for building with Win32 version 2.6 (#4835).
  * Change `compilerExtensions` and `ghcOptExtensionMap` to contain
    `Maybe Flag`s, since a supported extension can lack a flag (#4443).
  * Pretty-printing of `.cabal` files is slightly different due to
    parser changes. For an example, see
    https://mail.haskell.org/pipermail/cabal-devel/2017-December/010414.html.
  * `--hyperlink-source` now uses Haddock's hyperlinker backend when
    Haddock is new enough, falling back to HsColour otherwise.
  * `D.S.defaultHookedPackageDesc` has been deprecated in favour of
    `D.S.findHookedPackageDesc` (#4874).
  * `D.S.getHookedBuildInfo` now takes an additional parameter
    specifying the build directory path (#4874).
  * Emit warning when encountering unknown GHC versions (#415).

### 2.0.1.1 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) December 2017

  * Don't pass `other-modules` to stub executable for detailed-0.9
  (#4918).
  * Hpc: Use relative .mix search paths (#4917).

## 2.0.1.0 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) November 2017

  * Support for GHC's numeric -g debug levels (#4673).
  * Added a new `Distribution.Verbosity.modifyVerbosity` combinator
    (#4724).
  * Added a new `cabal check` warning about unused, undeclared or
    non-Unicode flags.  Also, it warns about leading dash, which is
    unusable but accepted if it's unused in conditionals. (#4687)
  * Modify `allBuildInfo` to include foreign library info (#4763).
  * Documentation fixes.

### 2.0.0.2 [Mikhail Glushenkov](mailto:mikhail.glushenkov@gmail.com) July 2017

  * See http://coldwa.st/e/blog/2017-09-09-Cabal-2-0.html
    for more detailed release notes.
  * The 2.0 migration guide gives advice on adapting Custom setup
    scripts to backwards-incompatible changes in this release:
    https://github.com/haskell/cabal/wiki/2.0-migration-guide
  * Add CURRENT_PACKAGE_VERSION to cabal_macros.h (#4319)
  * Dropped support for versions of GHC earlier than 6.12 (#3111).
  * GHC compatibility window for the Cabal library has been extended
    to five years (#3838).
  * Convenience/internal libraries are now supported (#269).
    An internal library is declared using the stanza `library
    'libname'`.  Packages which use internal libraries can
    result in multiple registrations; thus `--gen-pkg-config`
    can now output a directory of registration scripts rather than
    a single file.
  * Backwards incompatible change to preprocessor interface:
    the function in `PPSuffixHandler` now takes an additional
    `ComponentLocalBuildInfo` specifying the build information
    of the component being preprocessed.
  * Backwards incompatible change to `cabal_macros.h` (#1893): we now
    generate a macro file for each component which contains only
    information about the direct dependencies of that component.
    Consequently, `dist/build/autogen/cabal_macros.h` contains
    only the macros for the library, and is not generated if a
    package has no library; to find the macros for an executable
    named `foobar`, look in `dist/build/foobar/autogen/cabal_macros.h`.
    Similarly, if you used `autogenModulesDir` you should now
    use `autogenComponentModulesDir`, which now requires a
    `ComponentLocalBuildInfo` argument as well in order to
    disambiguate which component the autogenerated files are for.
  * Backwards incompatible change to `Component`: `TestSuite` and
    `Benchmark` no longer have `testEnabled` and
    `benchmarkEnabled`.  If you used
    `enabledTests` or `enabledBenchmarks`, please instead use
    `enabledTestLBIs` and `enabledBenchLBIs`
    (you will need a `LocalBuildInfo` for these functions.)
    Additionally, the semantics of `withTest` and `withBench`
    have changed: they now iterate over all buildable
    such components, regardless of whether or not they have
    been enabled; if you only want enabled components,
    use `withTestLBI` and `withBenchLBI`.
    `finalizePackageDescription` is deprecated:
    its replacement `finalizePD` now takes an extra argument
    `ComponentRequestedSpec` which specifies what components
    are to be enabled: use this instead of modifying the
    `Component` in a `GenericPackageDescription`.  (As
    it's not possible now, `finalizePackageDescription`
    will assume tests/benchmarks are disabled.)
    If you only need to test if a component is buildable
    (i.e., it is marked buildable in the Cabal file)
    use the new function `componentBuildable`.
  * Backwards incompatible change to `PackageName` (#3896):
    `PackageName` is now opaque; conversion to/from `String` now works
    via (old) `unPackageName` and (new) `mkPackageName` functions.
  * Backwards incompatible change to `ComponentId` (#3917):
    `ComponentId` is now opaque; conversion to/from `String` now works
    via `unComponentId` and `mkComponentId` functions.
  * Backwards incompatible change to `AbiHash` (#3921):
    `AbiHash` is now opaque; conversion to/from `String` now works
    via `unAbiHash` and `mkAbiHash` functions.
  * Backwards incompatible change to `FlagName` (#4062):
    `FlagName` is now opaque; conversion to/from `String` now works
    via `unFlagName` and `mkFlagName` functions.
  * Backwards incompatible change to `Version` (#3905):
    Version is now opaque; conversion to/from `[Int]` now works
    via `versionNumbers` and `mkVersion` functions.
  * Add support for `--allow-older` (dual to `--allow-newer`) (#3466)
  * Improved an error message for process output decoding errors
  (#3408).
  * `getComponentLocalBuildInfo`, `withComponentsInBuildOrder`
    and `componentsInBuildOrder` are deprecated in favor of a
    new interface in `Distribution.Types.LocalBuildInfo`.
  * New `autogen-modules` field. Modules that are built automatically at
    setup, like Paths_PACKAGENAME or others created with a build-type
    custom, appear on `other-modules` for the Library, Executable,
    Test-Suite or Benchmark stanzas or also on `exposed-modules` for
    libraries but are not really on the package when distributed. This
    makes commands like sdist fail because the file is not found, so with
    this new field modules that appear there are treated the same way as
    Paths_PACKAGENAME was and there is no need to create complex build
    hooks. Just add the module names on `other-modules` and
    `exposed-modules` as always and on the new `autogen-modules` besides.
  (#3656).
  * New `./Setup configure` flag `--cabal-file`, allowing multiple
  `.cabal` files in a single directory (#3553). Primarily intended for
  internal use.
  * Macros in `cabal_macros.h` are now ifndef'd, so that they
  don't cause an error if the macro is already defined. (#3041)
  * `./Setup configure` now accepts a single argument specifying
    the component to be configured.  The semantics of this mode
    of operation are described in
    <https://github.com/ghc-proposals/ghc-proposals/pull/4>
  * Internal `build-tools` dependencies are now added to PATH
    upon invocation of GHC, so that they can be conveniently
    used via `-pgmF`. (#1541)
  * Add support for new caret-style version range operator `^>=` (#3705)
  * Verbosity `-v` now takes an extended format which allows
    specifying exactly what you want to be logged.  The format is
    `[silent|normal|verbose|debug] flags`, where flags is a space
    separated list of flags. At the moment, only the flags
    +callsite and +callstack are supported; these report the
    call site/stack of a logging output respectively (these
    are only supported if Cabal is built with GHC 8.0/7.10.2
    or greater, respectively).
  * New `Distribution.Utils.ShortText.ShortText` type for representing
    short text strings compactly (#3898)
  * Cabal no longer supports using a version bound to disambiguate
    between an internal and external package (#4020).  This should
    not affect many people, as this mode of use already did not
    work with the dependency solver.
  * Support for "foreign libraries" (#2540), which are Haskell
    libraries intended to be used by foreign languages like C.
    Foreign libraries only work with GHC 7.8 and later.
  * Added a technical preview version of integrated doctest support (#4480).
  * Added a new `scope` field to the executable stanza. Executables
    with `scope: private` get installed into
    $libexecdir/$libexecsubdir. Additionally $libexecdir now has a
    subdir structure similar to $lib(sub)dir to allow installing
    private executables of different packages and package versions
    alongside one another.  Private executables are those that are
    expected to be run by other programs rather than users. (#3461)

    work-around for #2398)
  * Library support for multi-instance package DBs (#2948).
  * Improved the `./Setup configure` solver (#3082, #3076).

# 0.4  [Isaac Jones](mailto:ijones@syntaxpolice.org) Sun Jan 16 2005

  * Much thanks to all the awesome fptools hackers who have been
  working hard to build the Haskell Cabal!

  * __Interface Changes__:

    * __WARNING__: this is a pre-release and the interfaces are still
    likely to change until we reach a 1.0 release.

    * Instead of Package.description, you should name your
    description files <something>.cabal.  In particular, we suggest
    that you name it <packagename>.cabal, but this is not enforced
    (yet).  Multiple `.cabal` files in the same directory is an error,
    at least for now.

    * `./setup install --install-prefix` is gone.  Use `./setup copy`
    `--copy-prefix` instead.

    * The `Modules` field is gone.  Use `hidden-modules`,
    `exposed-modules`, and `executable-modules`.

    * `Build-depends` is now a package-only field, and can't go into
    executable stanzas.  Build-depends is a package-to-package
    relationship.

    * Some new fields.  Use the Source.

  * __New Features__

    * Cabal is now included as a package in the CVS version of
    fptools.  That means it'll be released as `-package Cabal` in
    future versions of the compilers, and if you are a bleeding-edge
    user, you can grab it from the CVS repository with the compilers.

    * Hugs compatibility and NHC98 compatibility should both be
    improved.

    * Hooks Interface / Autoconf compatibility: Most of the hooks
    interface is hidden for now, because it's not finalized.  I have
    exposed only `defaultMainWithHooks` and `defaultUserHooks`.  This
    allows you to use a ./configure script to preprocess
    `foo.buildinfo`, which gets merged with `foo.cabal`.  In future
    releases, we'll expose UserHooks, but we're definitely going to
    change the interface to those.  The interface to the two functions
    I've exposed should stay the same, though.

    * ./setup haddock is a baby feature which pre-processes the
    source code with hscpp and runs haddock on it.  This is brand new
    and hardly tested, so you get to knock it around and see what you
    think.

    * Some commands now actually implement verbosity.

    * The preprocessors have been tested a bit more, and seem to work
    OK.  Please give feedback if you use these.
