The Host Integration Server Product Team has just released the first Cumulative Update (CU) for HIS 2009. The cumulative update model is something that SQL Server and Biztalk Server also use to package and release product fixes on a more consistent schedule.
This cumulative update (CU) is a rollup update that contains the following items:
Details on the included fixes can be found in the following Knowledge Base article:
Cumulative update package 1 for Host Integration Server 2009
There are some additional fixes that are not yet listed in this KB article because the KB articles for those specific fixes are not yet completed. Once these other KB articles are completed, article 2587090 will be updated to include links to those articles as well.
You can download HIS 2009 CU1 via the View and request hotfix downloads link in the KB article. You would need to download the CU1 package that matches the HIS 2009 version (x86 or x64) that you have installed.
The HIS 2009 CU1 release follows the HIS 2010 CU1 released as described at http://blogs.msdn.com/b/sjackson/archive/2011/08/22/host-integration-server-2010-cumulative-update-1-cu1-is-available.aspx.
