Hi folks, all is left now is signing the installation with our Apple certificate. This would prevent the error on first launch that it's from an "unidentified developer".
We're waiting for the Apple certificate but if you don't mind that error message that can be quickly alleviated under System Security & Privacy we can send you the new software now upon request (request here). Otherwise, we expect another couple of days until it's signed.
