0.3

• Breaking changes: References have changed behaviour
• Reference doesn't extend Firebase anymore and has changed behaviour (see the [doc/02-references.md](documentation about References)).
• Reference data can be accessed with $reference->getData(), which returns an array, or directly with $reference['key'].
• Reference data can be updated with $reference->update(['key' => 'value']) or with $reference['key'] = 'value'.
• Improved test coverage.
• Added Makefile to ease test execution.
• Extended documentation and moved in to the doc folder.

0.2.4

• Add ext-mbstring as a requirement in composer.json (this will help the library to work on Heroku)
• Improved test coverage and added badges to README to show it off :)

0.2.3

• Fixed an error where the throw of an exception would throw an exception because of a wrong usage of sprintf()

0.2.2

• Fixed a case where an exception would be thrown inside an exception when no response was present.

0.2.1

• The Firebase library now has its own base URL handling so that a stable version of the HTTP adapter can be used.

0.2

• Better handling of server errors
  • Instead of using hard coded exception messages for assumed server errors, a single server error exception now includes the server's error message, if available.
• It is now possible to use the shallow parameter when performing a GET request. See the Firebase Docs on Query Parameters for a detailed description.
• Firebase::push() now returns the generated key as a string (not as an array ['name' => '...']) anymore

0.1.1

• The logger output now is less verbose and includes full URLs
• The README now includes an usage example
