Allocation Add-in Version 0.2
Version 0.2 of the Allocation Add-in has just been released.
It’s available from CodePlex here.
This new version includes support for SQL Server 2008 RTM and has a couple of new features.

The Allocation Map can now be set so that the entire file is rendered to fit the screen without the need for scrolling. This is the default view. Fit map is rendered asynchronously and is also cached.

There’s also the option to toggle on and off the table and allocation map.
