LibreOffice upgrade targets Windows integration and power users.

Key points: 

• the ability to centrally manage and lock-down the configuration with Group Policy Objects via Active Directory
• an optional new formula interpreter enables massively parallel calculation of formula cells using the GPU via OpenCL

I like this simple yet elegant part:

In addition to improving the desktop applications, LibreOffice is about to get an Impress Remote Control for iOS, letting iPhone users control presentations from their mobile devices. The app is awaiting review from Apple and should hit the App Store soon. Impress Remote is already available for Android.
