2 releases, 2 regressions in OpenStack. Should we cap eventlet version? 
The requirement bot can produce patches to update eventlet, patches 
which would run integration tests using Nova, Keystone, Neutron on the 
new eventlet version.

eventlet 0.18.2 broke OpenStack Keystone and OpenStack Nova

https://github.com/eventlet/eventlet/issues/299

eventlet 0.18.3 broke OpenStack Neutron
https://github.com/eventlet/eventlet/issues/301
https://bugs.launchpad.net/neutron/+bug/1546506

FYI eventlet 0.18.0 broke WSGI servers:
https://github.com/eventlet/eventlet/issues/295

It was followed quickly by eventlet 0.18.2 to fix this issue.

Sadly, it looks like bugfix releases of eventlet don't include a single 
bugfix, but include also other changes. For example, 0.18.3 fixed the 
bug #296 but introduced "wsgi: TCP_NODELAY enabled by default" optimization.

IMHO the problem is not the release manager of eventlet, but more the 
lack of tests on eventlet, especially on OpenStack services.

Current "Continious Delivery"-like with gates do detect bugs, yeah, but 
also block a lot of developers when the gates are broken. It doesn't 
seem trivial to investigate and fix eventlet issues.
