Since releasing TypeScript 0.8.1 a few weeks ago, we have heard a few reports of issues blocking the usage of source-map based debugging.  To address these, today, we’ve made available TypeScript 0.8.1.1, a bugfix release of 0.8.1.  This preview focuses on further refining the debugging experience and addressing rough edges in our initial support for source maps in Visual Studio.  Users of the Visual Studio plugin in particular are recommended to upgrade from 0.8.1 to 0.8.1.1.

The version 0.8.1.1 preview is available for Visual Studio, npm, and source.
