Class 'Auryn\Provider' not found

[funkytaco]

I removed my composer.lock file and started getting Class 'Auryn\Provider' not found with the line:
$injector = new \Auryn\Provider;

It looks like the working version is much older than the version I updated to.

It looks like maybe I just need to switch that line of code to:
$injector = new \Auryn\Injector;

Are there any other gotchas?

[rdlowrey]

$injector = new \Auryn\Injector; is the main thing to be aware of. Pre-1.0.0 releases aren't officially supported but it should be a pretty simple upgrade path. Just in case, though, here's the list of changes from the version you were using to the now-stable 1.0.x release series:

• Injector::buildExecutable() and Injector::execute() no longer accept the
  optional $makeAccessible parameter to allow invocation of protected/private
  methods.
• Provider class renamed -> Injector; Injector interface removed
• Exceptions consolidated into single InjectorException
• Indexed arrays may now be used for injection definitions
• New delegate (+) and definition (@) prefixes added for one-offs
• Removed ProviderBuilder class
• Renamed ReflectionPool -> Reflector
• Renamed Invokable -> Executable
• Add Injector::inspect() method for retrieving definitions
• Removed InjectorBuilder class
• Major internal refactoring
• Miscellaneous bugfixes

Thanks!
