Hi, I wasn't sure if this was more appropriate here or in the suggestions forum, but I've just been caught out by the fact that the wiki happily points us to the latest version of the underscore documentation, but the API server appears to be running version 1.4.4, which is pretty ancient (2.5 years ago!). Not sure if there have been any breaking changes (doesn't seem like the sort of library that would do that), but it would seem sensible to upgrade at some point - there are various useful features missing. At the very least the wiki needs to be clear about which version is supported! Cheers, Lucian
