I previously blogged about the availability of the Application Compatibility Toolkit 5.0, a tool that can help you find potential compatibility issues, particularly for corporate IE departments.
Since distribution of the beta download ended in October, I am excited to announce that the release candidate of ACT 5.0 is now available to download and can be used on XPSP2 with IE7 to help you find compatibility issues. You can find more about ACT 5.0 by visiting here. In addition to ACT 5.0, the IE7 Readiness Toolkit has more information, documentation and tools to help identify and resolve compatibility issues.
