Waves has release 6.0.1 with the introduction of a free plugin to those who are covered by the WUP on either the Gold, Broadcast + Production, Platinum, Diamond and Mercury bundles.
The new plug being the MV2 Volume Maximizer.
Apart from upgrading the Waves bundle software, you will also need to reauthorize your iLok for the v6.0.1 update and for MV2 to take effect. Authorization is not an instant process! You need to go to Waves, click the update link in your user account, and enter your iLok details. Eventually a license will appear in your iLok account for you to download. In doing so, this process will remove the v6.0 Waves license and replace it with the new v6.0.1. Since my 6.0.1 license is yet to appear in my iLok account I am unable to tell if this v6.0.1 will be backward compatible with Waves v6.0 software.
The v6.0.1 ilok asset is backward compatible with Waves v6.0 plugins
