hpack-0.34.2: CHANGELOG.md

## Changes in 0.34.2
  - Accept subcomponents as dependencies (close #382)

## Changes in 0.34.1
  - Fix a bug in `github: ...` introduced with `0.34.0`
    (f63eb19b956517b4dd8e28dc5785be5889a99298)

## Changes in 0.34.0 (deprecated)
  - Use `PreferNoHash` as default `GenerateHashStrategy`
  - Add support for library `visibility` (see #382)
  - Reject URLs for `github`

## Changes in 0.33.1
  - Add `GenerateHashStrategy`.  The default is `PreferHash` for `0.33.0` and
    will change to `PreferNoHash` with `0.34.0`. See
    https://github.com/sol/hpack/pull/390) for details.

  - Add command-line options `--hash` and `--no-hash`

## Changes in 0.33.0.1
  - Silently ignore missing hash when the cabal file content didn't change at
    all (for forward compatibility with #390)

## Changes in 0.33.0
  - Support GHC 8.8.1: `fail` is no longer a part of `Monad`. Instead, it lives
    in the `MonadFail` class. Adapting our code to this change meant changing
    the types of exporting functions, unfortunately, hence the major version
    bump.

## Changes in 0.32.0
  - Support Cabal 3.0
  - Switch reexported-modules to comma-separated list

## Changes in 0.31.2
  - Add default value for maintainer (see #339)

  - Show the header when printing to stdout (see #331)
  - Add help for `--numeric-version`(see #337)

## Changes in 0.31.0
  - Add `mixin` to the fields read by dependencies when they are
    objects (see #318)
  - `hpack` now returns with a successful exit code if the `.cabal`
    file is up to date, even if it was generated by a newer version of
    `hpack`.

## Changes in 0.30.0
  - Warn on duplicate fields (see #283)
  - Always render `cabal-version` as `x.y` instead of `>= x.y` so that `cabal
    check` does not complain (see #322)
  - Extend `build-tools` so that it subsumes Cabal's `build-tools` and
    `build-tool-depends` (see #254)
  - Add support for `system-build-tools`
  - Keep declaration order for literal files in c-sources (and other fields
    that accept glob patterns).  This is crucial as a workaround for
    https://ghc.haskell.org/trac/ghc/ticket/13786 (see #324)

## Changes in 0.29.7
  - Expose more stuff from `Hpack.Yaml` so that it can be used by third parties

  - Add `spec-version` (see #300)

## Changes in 0.29.5
  - Fix a regression related to indentation sniffing (close #310)

## Changes in 0.29.4

## Changes in 0.29.1
  - Infer `license` from `license-file`

## Changes in 0.29.0
  - Put the `cabal-version` at the beginning of the generated file. This Is
    required with `cabal-version: 2.1` and higher. (see #292)
  - With `cabal-version: 2.1` or higher omit `>=` when rendering (see #292)
  - Require `cabal-version: 2.2` when SPDX license identifiers are used (see #292)
  - Map cabal-style licenses to SPDX license identifiers when `cabal-version`
    is 2.2 or higher (see #292)

## Changes in 0.28.2
  - Exit with `exitFailure` on `AlreadyGeneratedByNewerHpack` or
    `ExistingCabalFileWasModifiedManually` in `Hpack.printResult`

## Changes in 0.28.1
  - GHC 8.4.1 compatibility

## Changes in 0.28.0
  - Add support for `cxx-options` and `cxx-sources` (see #205)
  - Add support for `data-dir` (see #100)
  - Generate valid `.cabal` files when `verbatim` is used top-level (see #280)

## Changes in 0.27.0
  - Local defaults are now resolved relative to the file they are
    mentioned in, not the CWD that hpack is invoked from.

## Changes in 0.26.0
  - Major refactoring of the exposed API (much cleaner now, but lot's of
    breaking changes!)
  - Remove Git conflict markers before checking the hash of any existing
    `.cabal` files (equivalent to `git checkout --ours`).  This allows to
    regenerate the `.cabal` file on conflicts when rebasing without passing
    `-f` in some cases and helps with preserving the formatting.
  - Allow local files to be used as defaults (#248)

## Changes in 0.25.0
  - Keep non-existing literal files on glob expansion (see #101)

## Changes in 0.24.0
  - Add support for `verbatim` Cabal escape hatch
  - Allow `version` be a numbers
  - Ignore fields that start with an underscore everywhere, not just globally

## Changes in 0.23.0
  - Add support for custom decoders to allow for alternate syntax (e.g. Dhall)
  - `generated-exposed-modules` and `generated-other-modules`, for populating
    the `autogen-modules` field (#207).
  - Corrected `cabal-version` setting for `reexported-modules` inside
    a conditional.

## Changes in 0.22.0
  - Add support for `defaults`
  - Add `--numeric-version`
  - Add support for `signatures`

    1.18; this is now done properly.
  - Accept bool for `condition` (see #230)

## Changes in 0.21.2
