We're delighted to announce that Microsoft Dynamics CRM 4.0 Update Rollup 21 released Thursday February 9th,2012!
Note regarding Podcast: Microsoft Dynamics CRM 4.0 Update Rollup 21 was discussed briefly during the CRM 2011 Update Rollup 6 Podcast delivered on October 26th, 2011.
NOTE: Due to the low volume of fix requests for CRM 4.0, the CRM SE team will stop shipping CRM 4.0 rollups on a regular schedule after Update Rollup 21. CRM SE will service CRM 4.0 requests on an individual basis using our Critical on Demand process.
CRM SE will continue to evaluate the need for Update Rollups for the remainder of CRM 4.0’s supported lifecycle. A rollup will be shipped if there is a significant increase in volume of fix requests or in the event that a rollup will benefit a majority of the 4.0 installation base.

Mismatched Update Rollup versions within a Microsoft Dynamics CRM deployment
In a scenario where you may be running many client workstations with Microsoft Dynamics CRM 4.0 for Microsoft Office Outlook, a common question is whether it is supported to run mismatched versions. For example, where Update Rollup 20 has been installed on the CRM Server but the Outlook clients are still on Update Rollup 15, or where Update Rollup 10 is on the CRM server but due to updates available to the Outlook client you have decided to install Update Rollup 20 on the clients without installing Update Rollup 20 on the server.
The general rule of thumb is to try to keep the versions in sync as much as possible. However, it is permissible (though not recommended as a long-term solution) to run mismatched Update Rollup versions on Outlook client and server, as Microsoft does do some testing of such combinations.
However, regarding the other Update Rollups (for example Rollups for the Microsoft Dynamics CRM 2011 Email Router or Microsoft Dynamics CRM 2011 Reporting Extensions), it is not supported nor recommended to run mismatched versions. A best practice is to update these components at the same time you update your CRM Server. Do the best you can to keep these Update Rollup versions in sync.
Internet Explorer 9 Compatibility
The Microsoft Dynamics CRM Sustained Engineering team extensively tested Microsoft Dynamics CRM 4.0 against pre-release versions of Internet Explorer 9 and continue to address compatibility issues, as they're reported, against the released (Released to Web) version of Internet Explorer 9.0. If necessary, they plan to release enhancements via future Microsoft Dynamics CRM 4.0 Update Rollup releases to assure compatibility with Internet Explorer 9.
