I already created a list of version numbers for SharePoint 2007 (which seems to be a little outdated as it seems).
Well, so now I give that a new try for SharePoint 2010:
| Update Name | Version number |
|---|---|
| RTM (all components) | 14.0.4763.1000 |
| RTM (farm build version) | 14.0.4762.1000 |
| June 2010 CU | 14.0.5114.5003 |
| August 2010 CU | 14.0.5123.5000 |
| October 2010 CU | 14.0.5128.5000 |
| December 2010 CU | 14.0.5130.5002 |
| February 2011 CU | 14.0.5136.5002 |
| April 2011 CU | 14.0.5138.5000 |
