For the past few months, we've been investigating a significant bug when 
enabling SSL for oslo.messaging connections to RabbitMQ.[0] Thanks to 
some patient and excellent investigation, it was tracked down to an 
issue in the amqp library that we use in oslo.messaging. The fix has now 
been released as 2.4.1, and we've updated the requirements on master to 
reflect that, but we can't backport requirements changes to the stable 
branches. Since this affects releases going back to Pike, that's 
potentially a lot of affected users. We're planning to release note[1] 
all of the stable branches to communicate the need to use a newer 
version of the library, but I also wanted to send an email to the list 
in order to help get the word out. Basically, since we can't fix this in 
the library itself I'm running a publicity campaign to let everyone know 
what the fix is. :-)

If you have any questions, feel free to reach out here or on IRC in 
#openstack-oslo. Thanks.
