Subject Re: Release schedule
Date Wed, 04 Oct 2006 17:07:07 GMT

I put a post in the user forum for this, but thought I'd add something to
this thread.  I'm concerned about backward compatibility.  I've got a test
environment with all brokers at 4.0.1, except one I'm upgrading to 4.1. 
This would be how our production environment would be upgraded - a machine
or so at a time.

However, the 4.0.1 brokers will not connect to the 4.1 broker, giving the
following exception:

There must be an upgrade path for 4.1.  If that means I have to go to 4.0.2
(which I did not try yet), that is OK.  But, I can't possibly tell my
management that I have to upgrade the AMQ version on all 50 or so machines
we have in production.
