ANN RabbitMQ Java Client 6.0.0 Milestone 1 is released

[Arnaud Cogoluègnes]

On behalf of the RabbitMQ team I'm happy to announce that the RabbitMQ
Java Client library 6.0.0 Milestone 1, a preview release, is available
for community testing.

This is the first milestone release for 6.0.0. It introduces new
metrics on published messages. This pre-release introduces also a
breaking change which impacts users implementing the MetricsCollector
interface in their applications. Users of the 5.x.x series are
encouraged to test this version.

* Metrics for confirmed and unsuccessful outgoing publishes

Consult the release change for more details [1].

Was the breaking change just the addition of new methods on the MetricsCollector interface? If so I would suggest using Java 8's default methods [1] so you can passively add methods to interfaces without breaking other implementers.

Good point. I'll consider this for the 5.x branch, to benefit from the
feature as soon as possible in a stable version, as a few maintenance
releases of 5.x may be done before 6.0 becomes GA.

Nevertheless, 6.0 is likely to keep this breaking change. I'm not fond
of keeping empty default methods forever in a retrofitted interface,
they would look like second-class citizens, which they're not in this
case.
