Bump RabbitMQ.Client from 5.1.0 to 6.2.1

[dependabot-preview]

Bumps RabbitMQ.Client from 5.1.0 to 6.2.1.

Release notes

Sourced from RabbitMQ.Client's releases.

6.1.0

Changes Between 6.0.0 and 6.1.0

This release continues with improvements to memory use and object allocations.

A full list of changes can be found in the GitHub milestone: 6.1.0.

6.0.0

Changes Between 5.2.0 and 6.0.0

This major release of this client introduces substantial improvements in terms of memory footprint and throughput. They come at the cost of minor but important breaking API changes covered below.

The client now requires .NET Framework 4.6.1 or .NET Standard 2.0. Earlier versions are no longer supported by the 6.x series.

Key improvements in this release have been the result of hard work by our stellar community members (in no particular order): @stebet, @bording, @Anarh2404, @danielmarbach, and others.

A full list of changes can be found in the GitHub milestone: 6.0.0.

The Switch to System.Memory (and Significantly Lower Memory Footprint that Comes with It)

The client now uses the System.Memory library for message and command payloads. This significantly reduces object allocation and GC pressure for heavy workloads but also potentially requires application changes: consumer delivery payloads are now of instance System.ReadOnlyMemory<byte> instead of byte[].

While there's an implicit conversion for these types, instances of System.ReadOnlyMemory<byte> must be copied or consumed/deserialised before delivery handler completes. Holding on to delivered payloads and referencing them at a later point is no longer safe.

The same applies to publishers and the IModel.BasicPublish method: prefer using System.ReadOnlyMemory<byte> over byte[] and dont' assume that this memory can be retained and used outside of the scope of the publishing function.

GitHub issue: #732

Timeouts Use System.TimeSpan

All timeout arguments now use System.TimeSpan values.

GitHub issue: #688

Reduced Public API Surface

No major changes here but this is potentially breaking. Only public classes that were never meant to be publicly used have been turned internal to the client.

Changelog

Sourced from RabbitMQ.Client's changelog.

Changes Between 6.2.0 and 6.2.1

6.2.0 was published incorrectly, resulting in version 6.2.1

GitHub milestone: 6.2.1.

Changes Between 6.1.0 and 6.2.0

This releases primarily focuses on efficiency improvements and addressing bugs introduced in 6.x releases.

A full list of changes can be found in the GitHub milestone: 6.2.0.

Key highlights include:

• Concurrent publishing on a shared channel is now safer. We still recommend avoiding it when possible but safety properties have been improved by changing how outgoing frame sequences are serialised.

  Contributed by @bollhals.

  GitHub issue: #878

• Batch publishing using System.ReadOnlyMemory<byte> payloads instead of byte arrays.

  Contributed by @danielmarbach.

  GitHub issue: #865, #892
