The latest Application Compatibility Toolkit (ACT) release, ACT 5.0.5428.1080 is publicly available and can be downloaded here.
To give you some background, ACT helps customers understand their application compatibility situation by helping identify which applications are compatible with Vista, IE7, and IE8 and which require further testing. ACT allows compatibility data to be uploaded from individual machines to a central location for analysis, grouping and reporting. Once an issue has been identified, help will be available on how to resolve a particular issue or create a workaround. Furthermore, partners and customers using ACT are able to post comments to the Online Application Community, where they can share data and information about application compatibility testing.
The IE components of ACT are:
Overall, these tools help customers lower their costs for application compatibility testing, prioritize their applications, and deploy Internet Explorer more quickly.
The work flow for identifying application compatibility issues before rolling out a new version of IE8 is shown below:

We added logging for twelve new Application Compatibility Events in IE8, as shown in the table below. Including the IE7 events, we now currently log 31 compatibility events. The Internet Explorer Compatibility article contains more information on these events.

In the past, we noticed that the ACT tool helped identify the compatibility issues that occur in a line of business application or website, however, the tool itself did not provide any guidance for remediation. In IE8, we are providing a resource that gives exactly that information. The article is linked directly in the IECTT logged message or is directly available here. The article covers the following topics for all IE7 and IE8 compatibility events:
We will be adding additional examples and remediation to this article before the final IE8 release.
As you can see, we refined our Application Compatibility logging in IE8 and have provided a useful resource in the IE Application Compatibility article. We look forward to you trying it out and giving us feedback in the IE newsgroups.
