On July 16th, the new CU (cumulative update) package for BizTalk 2010 became available for download here: http://support.microsoft.com/kb/2855367.
Together with this, CU3 for Adapter Pack 2010 was released for download here: http://support.microsoft.com/kb/2617150
According to this blog post, it features more than 25 bug fixes in both packages together, which seems to be more than normal.
This shows again that the team behind BizTalk is still pushing out updates as bugs are found, which we can all appreciate and support off course!
The full list of all CU’s and service packs for all BizTalk servers can be found here: http://support.microsoft.com/kb/2555976.
It already includes CU6 as well.
After installing, you will need to reboot your BizTalk server(s) to take effect.
