[chef] Is there an update cycle for bento basboxes?

[Torben Knerr < >]

Ohai!

Are the bento baseboxes on S3 (as listed on
https://github.com/opscode/bento) updated regularly, e.g. when new
Chef versions come out?

Just wanted to know whether I can expect to always get the same box
from the S3 Url or whether the contents of the box might change over
time.

Cheers, Torben
