# 0.2.13

• Eliminate most compiler warnings when compiling with GHC-7.10.

• Bump lower bound on the version of optparse-applicative to 0.11.0.2. This avoids issues when building with transformers-compat.

• Reduce compilation time with text<1.2.0.5 by avoiding usage of toCaseFold from the case-insensitive package.

• Dropped dependency on the error package.

• Issue 43: Support detection of the version control system when the package directory and thus the cabal file is in sub-directory of the repository.

# 0.2.12

• Added support for transformers-0.3.0.0. This changes allows usage of configuration-tools along with packages that depend on ghc, which in turn depends on transformers-0.3.0.0.

# 0.2.11

• Added support for Cabal-1.18. This is supposed to make the build more robust and simplify integration with existing build infrastructure and other packages.

# 0.2.10

• Moved all internal APIs to the Internal name space. Exposing them in 0.2.9 was considered a bug.

• Configuration files can be formatted either as JSON or as YAML. For remote configuration files the HTTP Content-Type header is used to determine the format, for local files the file suffix is used. The default format is YAML.

• Set the HTTP accept header for JSON and YAML when requesting remote configuration files.

# 0.2.9

• Use tight constraint for all validation functions. Previously the constraint where unnecessarily restrictive.

• Added updateProperty function that generalized %.: in the same way as setProperty generalizes ..:.

• Added a validation function for configuration file arguments.

• Allow usage of more than a single --config-file option on the command line.

• Support for static configuration file locations. Configuration files can be marked as required or optional.

• Support for loading of configuration files form HTTP and HTTPS URLs. There are new flags for disabling validation of SSL certificates and white listing SSL certificates based on their fingerprint.

• Added tools for updating configurations with a monoid instance.

• Added two new option parsers for boolean flags.

• The boolOption_ parser uses the syntax --feature and --no-feature to enable and respectively disable a feature.

• The enableDisableFlag parser uses the syntax --enable-feature and --disable-feature to enable and respectively disable a feature.

• Refactored the module layout. The API of the existing modules is is backward compatible, but a lot of code got moved into submodules.

• Improved documentation.

• Improved test suite.

# 0.2.8

• Added validation functions for Boolean values, numeric values and orders.

• Added operator !..: for parsing of configuration values that are required to be present in a configuration file, thus preventing the default value from being used.

• More consistent usage of case in metavar values.

• Drop support for optparse-applicative < 0.10.

# 0.2.7

• Added view function for lenses to Configuration.Utils.Internal.

• Added support for validation of configuration values.

• Added module Configuration.Utils.Validation that provides primitives for validating different basic configuration values.

# 0.2.6

• For git repositories include also light-weight (non-annotated) tags in the version description.

• Added new function boolReader, boolOption, fileOption, and eitherReadP to Utils.

• Added new function maybeOption and improved documentation about Maybe config values.

• Included optimisation level into long info.

# 0.2.5

• Configuration.Utils.Setup: export mkPkgInfoModules function that modifies a given UserHooks record to generate an PkgInfo module during configuration.

# 0.2.4.1

• Support for optparse-applicative >= 0.10.

# 0.2.4

• Configuration.Utils.Setup: fixed generation of PkgInfo module for package configurations with explicit flags.

• Improved documentation for Maybe values.

# 0.2.3

• Show the help options in the options summary message.

• Add -? as short version of for --help in addition to -h.

• Remove showHelpOnError and disambiguate from option parser preferences.

• Added file INSTALL_ON_WINDOWS.md with installation instructions for windows to the package.

# 0.2.2

• Add Lens piOptionParserAndDefaultConfiguration that gives simultaneous accesses to piOptionParser and piDefaultConfiguration which allows changing the type parameter of ProgramInfo a.

• Introduce function setProperty. It is used as the ..: operator but allows to specify a custom parser for the property value instead of the default parseJSON from the FromJSON instance.

• Introduce operators (<*<), (>*>), (<$<), (>$>) and deprecate (⊙) and (<.>).

# 0.2.1

• Fix build with GHC-7.6 by relaxing lower bounds on some dependencies.

First release.
