* Added caching of repository metadata (faster startup times & failover if packagist is down)
|
||||
* Added include_path support for legacy projects that are full of require_once statements
|
||||
* Added installation notifications API to allow better statistics on Composer repositories
|
||||
* Added autoloading support for root packages that use target-dir
|
||||
* Improved repository protocol to have large cacheable parts
|
||||
|
||||
* 1.0.0-alpha2 (2012-04-03)
