It’s good practice for a developer to refer to product hotfixes whenever they face any rare/new exception. For past two years, commerce server team has released many hot fixes for routine/rare exceptions but there is no single page to list all of them. In this article, I consolidated and listed many of commerce server 2009 and commerce server SP2 hot fixes. Hope this page will become one stop hotfix shop for the developers.
