In an earlier post I gave an overview of the version numbers of the different BizTalk Server versions. From my blog stats I can see that there quite a lot of people looking for this information.
I also promised to update the overview as soon as a new version of service pack is available. To keep the promise I added the recent beta of BTS2k9.
| Product name | Service pack | Version number |
| BizTalk Server 2004 | 3.0.4902.0 | |
| BizTalk Server 2004 | SP1 | 3.0.6070.0 |
| BizTalk Server 2004 | SP2 | 3.0.7405.0 |
| BizTalk Server 2006 | 3.5.1602.0 | |
| BizTalk Server 2006 R2 | 3.6.1404.0 | |
| BizTalk Server 2009 (beta1) | 3.8.104.5 |
This information is now also provided by Microsoft in the BizTalk Server 2009 help. See help topic ‘What Version of BizTalk Server Do I Have?’.
