As part of our code cleanups and reorganizations, we've added some new features to version 3.0.3. Previously, array references could only be used in string expansions. e.g. "%{Cisco-AVPair[2]}". This limitation is problematic, so we've fixed it. You can now use array references in "unlang", in every place attribute references were allowed before. In some situations, this doesn't make much difference. In others, it makes a lot of difference. e.g. switch &Cisco-AVPair[2] {...} And even better (as an artificial example): update reply { Filter-Id[1] := &request:Cisco-AVPair[2] } In previous versions, it was impossible to update the second attribute of the same name. You could either update the first one, or delete all of them, and re-create them. It's now possible to "reach into" a list, and re-write individual attributes. Other new features include more sanity checks on inputs, so that more errors in the configuration files are caught. This means that dynamic expansions are pre-parsed, as are regular expressions. Please respond if there are issues, questions, concerns, etc. Alan DeKok.
