== v2.0.0 [2013-01-30] Michael Granger <ged@FaerieMUD.org>

- Make missing Configurability::Config values return nil instead of
  auto-vivifying to a Struct.

  This is not a backward-compatible change, but in practice, far more
  work was done to detect non-existant values than was saved by the
  debatable convenience of being able to auto-create nested structs.

- Update to loggability 0.4 and add Rubinius (1.9-mode) fixes.


== v1.2.0 [2012-05-09] Michael Granger <ged@FaerieMUD.org>

- Added a command-line utility.
- Convert logging to use Loggability.


== v1.1.0 [2012-04-25] Michael Granger <ged@FaerieMUD.org>

Add a 'defaults' API that allows defaults to be gathered from any
object with configurability and merged into a hash keyed by the
object's config_key. This hash can be used to generate an initial
unified config file for all configurable parts of a given system.


== v1.0.10 [2012-03-13] Michael Granger <ged@FaerieMUD.org>

- Fix log level message.


== v1.0.9 [2012-01-27] Michael Granger <ged@FaerieMUD.org>

Fix problems associated with inheritance.

- Added a Hash of configure methods that have already been called
  as pairs of Methods and Config sections. (Configurability.configured)
- Use the `configured` hash to avoid re-calling configure with the same
  config section more than once when a class with Configurability is
  inherited.
- Configurability.install_config -- Only use the index operator method
  of the config object if it actually has the config_key as a key. Else
  configure with +nil+.
- Support different whitespace conventions in different YAML libraries

Thanks to Mahlon E. Smith for reporting this bug, and for pairing with
me to fix it.
