[atlas] Updated RIPE Atlas roadmap

Dear colleagues, we have considered the feedback we have received from you in the previous few months, on this list and MAT-wg mailing list, and last week we have made an updated version of the roadmap: http://roadmap.ripe.net/ripe-atlas/ We have added few new items under "requested features", and shifted some of the previously requested and planned towards "in progress". We are updating this document every two months, so you can expect newer requests to be added early next year. Regards, Vesna
