Denis has created a 'helios' flag (see 
) which can be used to tag plan items against the Helios release, just like many of us did with the 'galileo' flag last year (see 
). Note that this flag is opt-in, i.e. if you wish to use it, it has to be turned on for your project (it's already been turned on for the projects that used the 'galileo' flag last year). For an overview of how we are using this in Modeling projects, see . I also blogged last year about the motivation behind this flag – see .
