Any chance we will see a 1.11? At least 1.10 release notes should be updated to note this, no? Right now it claims to be 100 backwards compatible.

According to SVN history, the code in MapConfiguration has been patched to fix CONFIGURATION-556 [1]. The fact that the MapConfiguration can no longer be updated is probably an undesired side effect. I assume that this will work again with version 2.0. In this version, MapConfiguration just stores the Properties object passed to the constructor. So updates are not a problem.
