This is a "patch" release of DevForce 2010.
As of version 6.1.9, DevForce 2010 now uses three digit semantic versioning. The 6.1.11 release differs from the prior release in the inclusion of several minor fixes.
If you have a Code First model, note that the version of the DevForce 2010 Code First NuGet package must match the version of DevForce installed. See here for more information.
