Changes between 2.3.2 and 2.3.3 (unreleased)

No changes yet.

Changes between 2.3.1 and 2.3.2 (July 10th, 2020)

Safer Encoding Handling When Serialising Message Properties and Headers

Contributed by @bbascarevic-tti.

GitHub issue: ruby-amqp/amq-protocol#76

Changes between 2.3.0 and 2.3.1 (April 8th, 2020)

Support for connection.update-secret

Used together with the rabbitmq-auth-backend-oauth2 plugin.

Squashed a gemspec Warning

GitHub issue: ruby-amqp/amq-protocol#75.

Changes between 2.2.0 and 2.3.0 (Jan 8th, 2018)

Support for Additional URI Query Parameters

GitHub issue: #67, #68, #69.

Contributed by Andrew Babichev.

Changes between 2.1.0 and 2.2.0 (May 11th, 2017)

Timestamps are Encoded as 64-bit Unsigned Integers

This is a potentially breaking change. It is recommended that all applications that use this gem and pass date/time values in message properties or headers are upgraded at the same time.

GitHub issue: #64.

Contributed by Carl Hoerberg.

Changes between 2.0.0 and 2.1.0 (January 28th, 2017)

Ruby Warnings Squashed

Contributed by Akira Matsuda.

GitHub issue: #62

Byte Array Decoding

Byte array values in types now can be decoded (to the extent Ruby type system permits) by this library.

GitHub issue: #58

Changes between 1.9.x and 2.0.0

2.0.0 has breaking changes in header encoding.

Signed Integer Encoding in Headers

Integer values in headers are now encoded as signed 64-bit (was unsigned 32-bit previously, unintentionally).

This is a breaking change: consuming messages with integers in headers published with older versions of this library will break!

Signed 16 Bit Integer Decoding

Signed 16 bit integers are now decoded correctly.

Signed 8 Bit Integer Decoding

Signed 8 bit integers are now decoded correctly.

Contributed by Benjamin Conlan.

Changes between 1.8.0 and 1.9.0

Performance Improvements in AMQ::BitSet

AMQ::BitSet#next_clear_bit is now drastically more efficient (down from 6 minutes for 10,000 iterations to 4 seconds for 65,536 iterations).

Contributed by Doug Rohrer, Dave Anderson, and Jason Voegele from Neo.

Changes between 1.7.0 and 1.8.0

Body Framing Fix

Messages exactly 128 Kb in size are now framed correctly.

Contributed by Nicolas Viennot.

Changes between 1.6.0 and 1.7.0

connection.blocked Support

connection.blocked AMQP 0.9.1 extension is now supported (should be available as of RabbitMQ 3.2).

Changes between 1.0.0 and 1.1.0

Performance Enhancements

Encoding of large payloads is now done more efficiently.

Contributed by Greg Brockman.

Changes between 1.0.0.pre6 and 1.0.0.pre7

AMQ::Settings

AMQ::Settings extracts settings merging logic and AMQP/AMQPS URI parsing from amq-client. Parsing follows the same convention amqp gem and RabbitMQ Java client follow.

Examples:

AMQ::Settings.parse_amqp_url("amqp://dev.rabbitmq.com")            # => vhost is nil, so default (/) will be used
AMQ::Settings.parse_amqp_url("amqp://dev.rabbitmq.com/")           # => vhost is an empty string
AMQ::Settings.parse_amqp_url("amqp://dev.rabbitmq.com/%2Fvault")   # => vhost is /vault
AMQ::Settings.parse_amqp_url("amqp://dev.rabbitmq.com/production") # => vhost is production
AMQ::Settings.parse_amqp_url("amqp://dev.rabbitmq.com/a.b.c")      # => vhost is a.b.c
AMQ::Settings.parse_amqp_url("amqp://dev.rabbitmq.com/foo/bar")    # => ArgumentError

AMQ::Protocol::TLS_PORT

AMQ::Protocol::TLS_PORT is a new constant that contains default AMQPS 0.9.1 port, 5671.
