It is a bug in our update script. The snapshots are not really new
every hour, but the same snapshot with a new timestamp. I'll see if
I can fix that.

There will be new contents once every day.

We are only interested in reports about real bugs. :-)

The BEAM compiler and run-time system are supposed to be stable all the time,
so if something that worked in R11B doesn't work it is probably a bug.
But it could be a good idea to try at least two snapshots a few days apart
before reporting a potential bug.

Bugs in hipe are not worth reporting, unless the same bug occurs in R11B-5.

We (the Erlang/OTP group at Ericsson) often break hipe when we update
the compiler (e.g. adds new instructions) and/or run-time system.
The HiPE group in Uppsala mends hipe as soon as our code gets committed to
their CVS repository (which usually happens once a week).
