Its really nice to see them bringing in even more flexibility in platforms and environments.

I just hope they had taken a little bit more care in ensuring backward compatibility - both my apps (which I have been running for 7+ months) lost code deployment ability (errors on deploy). The fact that it happened exactly at a time we discovered a major issue in our code base and were stuck without being able to push hot fixes was a major bummer.

Shot off an email to their support 2 hours back - haven't heard back yet.

Fortunately, we sniffed the issue to the new buildpack and found a work around by pointing our apps to use an older buildpack (https://devcenter.heroku.com/articles/buildpacks). While it caused us real heartburn for quite some time, kudos to them for building an infrastructure that is extremely configurable (which enabled the workaround).

Update: Heroku support got back with the same work around. They are debugging the issue with the new buildpack.

We have a similar problem - the upgrade means our slugs have to be recompiled, and heroku's slug compiler times out after 15 minutes. That sounds like a long time, but the development version of gevent can take a good 5-10 minutes to build.

We got an email back from heroku suggesting we push with half the dependencies first, then the other half. Not an ideal solution, as it would take our production app offline.
