TL;DR

Bunny 2.0.0-rc1 is released to rubygems.org.

2.0.0 is a minor feature and bug fix release that drops Ruby 1.9 and 1.8 support.

Changes between Bunny 1.7.0 and 2.0.0

Bunny 2.0 doesn’t have any breaking API changes but drops Ruby 1.8 and 1.9 (both EOL’ed) support, hence the version.

Minimum Required Ruby Version is 2.0

Bunny 2.0 requires Ruby 2.0 or later.

Reduced Timeout Use

Bunny::ContinuationQueue#poll no longer relies on Ruby’s Timeout which has numerous issues, including starting a new “interruptor” thread per operation, which is far from efficient.

Bunny::Channel#basic_ack and Related Methods Improvements

Bunny::Channel#basic_ack, Bunny::Channel#basic_nack, and Bunny::Channel#basic_reject now adjust delivery tags between connection recoveries, as well as have a default value for the second argument.

Logger Output Remains Consistent

Setting the @logger.progname attribute changes the output of the logger. This is not expected behaviour when the client provides a custom logger. Behaviour remains unchainged when the internally initialized logger is used.

Contributed by Justin Carter.

prefetch_count is Limited to 65535

Since basic.qos’s prefetch_count field is of type short in the protocol, Bunny must enforce its maximum allowed value to 2^16 - 1 to avoid confusing issues due to overflow.
