OpenACS 5.10.1 final released

We are proud to announce the release of OpenACS 5.10.1 [1]. The release of OpenACS 5.10.1 contains the 100 packages of the oacs-5-10 branch. These packages include the OpenACS core packages, the major application packages (e.g., most of the ones used on OpenACS.org), and DotLRN 2.10.1. The release is probably the most secure and with the most tested code since ever. Altogether, OpenACS 5.10.1 differs from OpenACS 5.10.0 by the following statistics
