1) We would love an equivalent to the HEROKU_RELEASE runtime variable: A strictly increasing int that is incremented with any change to the environment (deploys or env/secrets).

It’s nice to have a single roll up for all of the knobs — “what was the state of the environment” — to tag in things like crash logs.

(It’s also something we can’t easily tool ourselves.)

2) One click dashboard rollback button. Didn’t realize how much we missed this from Heroku.

3) Meta: Public roadmap and feature request tracker. Fly has a habit of surprising, usually pleasantly!, but it’d be nice to know how close or far off something on our wishlist is. (Render seems to do this well.)
