TL;DR
Bunny 1.6.0.rc2 is released to rubygems.org.
1.6 is a minor feature release that makes the library use TLS 1.0 or later when possible.
Changes between Bunny 1.5.0 and 1.6.0-rc2
TLSv1 by Default
TLS connections now prefer TLSv1 (or later, if available) due to the recently discovered POODLE attack on SSLv3.
Contributed by Michael Klishin (Pivotal) and Justin Powers (Desk.com).
GH issues:
Socket Read and Write Timeout Improvements
Bunny now sets a read timeout on the sockets it opens, and uses
IO.select timeouts as the most reliable option available
on Ruby 1.9 and later.
GH issue: #254.
Contributed by Andre Foeken (Nedap).
Inline TLS Certificates Support
TLS certificate options now accept inline certificates as well as file paths.
