In August we released The Dark Zebra. Since then we've concentrated on fixing all niggles and bugs that have piled up in the last couple of years. Most of these were quite odd, such as disappearing AU guis when VSTs were used in Live. So we racked our brains 24/7 to figure things out. The result is a maintenance update for virtually everything, and it's pretty much ready for release.
It got late though - as we're all off for holidays and in case we missed anything all-too-serious, we would post public betas rather than call them official releases

UPDATE: Everything is Rev 1331 now, improved installers, faster Diva
Installers for Mac, Revision 1331:
ACE, Bazille, Diva, Filterscape, MFM2, Triple Cheese, Uhbik, Zebra2
Installers for Win, Revision 1331:

Furthermore:
Important: After installation every plug-in should show "Rev. 1331" somewhere on the editor. We noticed that sometimes it's necessary to remove AUs first before installation. We think that's only the case for our beta testers (cached installers...), but if you can't see any Revision number, you might have to install again.
Beta installers for ZebraHZ will be available for owners of The Dark Zebra from the support area of our website from tonight (you need to log into your account). We've simply added them into a subfolder of the normal zip file. Note that we've seperated ZebraHZ from Zebra to avoid any confusion with installers and what to install when. So in future you can insatll Zebra and ZebraHZ seperately, but you need to enter the Zebra2 serial number once in ZebraHZ as well.
Updates for ZebraCM will be sent to CM early next year, updates to TyrellN6 will surface on Amazona once a new gui is designed (so I hear).
