Just got this on my email!
“Ableton has released a beta version of Live 8.4, which introduces native 64-bit support. The 64-bit version of Live will allow you to use more than four gigabytes of RAM. This means you can work with Live Sets (including Sets using third-party plug-ins and ReWire configurations) that are much larger and more memory intensive than in the 32-bit version. Registered users of Live 8, Suite 8, Live Intro and Live Lite 8 can download the beta now.
Note: The 64-bit version of Live 8 does not support Max for Live, video, or The Bridge. We are currently working with our partners to add support for these features. For more information and system requirements please see this Knowledge Base article.”
Everyone join in!
