Aurora is no more because it was not necessary for stability (when nightly merges to beta it is already very stable, this improved a lot over time) and incurred a cost on speed of development (one less stop for the train to ride). DevEdition is now based on Beta and extremely stable. I use it alongside the stable version on both of my main computers in an equal way and I have max. 1-2 issues in DevEdition in a year (and those issues do not even prevent me from doing my work).
