hpack-0.31.2: CHANGELOG.md

## Changes in 0.31.2
  - Add default value for maintainer (see #339)
  - Escape commas and spaces in filenames when generating cabal files

## Changes in 0.31.1
  - 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

## Changes in 0.29.6
  - Add `spec-version` (see #300)

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

## Changes in 0.29.4
  - Desugar ^>= when dependency is a string (see #309)
  - Add support for Apache, MPL and ISC when inferring `license` (see #305)

## Changes in 0.29.3

## Changes in 0.29.2

## 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)

    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

    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
