Full Changelog: v2.0.4...v2.0.5

v2.0.4

• Restores the server.Publish(topic string, payload []byte, retain bool, qos byte) error method from v1.3.2 as a convenience function which utilizes server.InjectPacket, by @mochi-co for #113
• Refactors Client creation to allow developers to more easily create and use Clients and InlineClients as passing server.ops was difficult and NewClient, NewInlineClient, and newClientStub presented unnecessary code duplication. Use server.NewClient instead of mqtt.NewClient, by @mochi-co. Many thanks to @chenji1990 for their supportive PR regarding this matter!

v2.0.1

What's Changed

• Everything. Thank you for your patience - by @mochi-co
• Provides full compliance with MQTT v5 specification
• Fixes all outstanding v1 related issues.

Full Changelog: v1.3.2...v2.0.1

---

This much-awaited release represents a total ground-up rewrite of the entire project in order to primarily support all of the features and compliance requirements detailed in the MQTT v5 specification. As such, it represents an absolute breaking change from the v1 series of the broker.

In particular, the following have changed which may interrupt your existing implementations:

• Auth interfaces, persistence interfaces, and the events callback system have been replaced with the new universal Hooks system.
• Inline Publish has been replaced by Inject Packet.
• The way the server is initiated and configured has changed.

Please refer to the new readme for full information on all changes, and open an issue if you have any questions or feedback! 🙂

v1.3.2

What's Changed

• Provides a fix for new data races in inflight messages system by @mochi-co in #99 and @muXxer in #96
• Increased size of InlineMessages publish buffer from 1024 to 4096 in light of #95 by @mochi-co

Full Changelog: v1.3.1...v1.3.2

This issue does not effect users in controlled environments who do not use QOS values higher than 0, but users who do should upgrade to this release at the soonest possible convenience.

This patch release addresses an issue #98 and #96 in which a data race introduced by #90 when the primary server routine and client routines attempted to access the client inflight messages map at the same time, causing fatal errors.

The issue was reproduced placing the server under heavy load with inovex/mqtt-stresser, using qos=2 for both the publisher and subscriber (see #98).

Profiling the solution before and after shows a small but negligible reduction in mallocs (good thing). When running the above mentioned stress tests, no data races or crashes are detected.

With many thanks to @muXxer for identifying the issue and providing a potential solution in #96
