v2.7.2

This release fixes an issue in the proxy code generation
that prevented an optimization in proxy identifier getter methods.

Specifically, if you have a method like following in your proxied
class, then this release will ensure that a call to that method
will not initialize your proxy if not needed:

class MyEntity
{
    private $id;
    public function getId() : ?int
    {
        return $this->id;
    }
}
