TL;DR
Bunny 0.9.2 is released to rubygems.org.
This is a stability improvement release that is completely backwards compatible
with 0.9.0.
We encourage all Bunny users to upgrade to it.
Changes between Bunny 0.9.1 and 0.9.2
Reliability Improvement in Automatic Network Failure Recovery
Bunny now ensures a new connection transport (socket) is initialized before any recovery is attempted.
Changes between Bunny 0.9.0 and 0.9.1
Reliability Improvement in Bunny::Session#create_channel
Bunny::Session#create_channel now uses two separate mutexes to avoid
a (very rare) issue when the previous implementation would try to
re-acquire the same mutex and fail (Ruby mutexes are non-reentrant).
Full change log can be found on GitHub.
