Changes Between 6.3.1 and 6.4.0

This release adds the ability to specify a maximum message size when receiving data. The default values are:

  • RabbitMQ .NET client 7.0.0 and beyond: 128MiB
  • RabbitMQ .NET client 6.4.0 up to 7.0.0: no limit by default

Receiving a frame that specifies a content larger than the limit will throw an execption. This is to help prevent situations as described in this discussion.

To set a limit, use the set MaxMessageSize on your ConnectionFactory before opening connections:

// This sets the limit to 512MiB
var cf = new ConnectionFactory();
cf.MaxMessageSize = 536870912;
var conn = cf.CreateConnection()`

This release contains some important bug fixes:

Changes Between 6.2.1 and 6.2.3

GitHub milestone: 6.2.3 GitHub milestone: 6.2.2

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

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

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.

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.

GitHub issue: #714

Requires .NET Framework 4.6.1 or .NET Standard 2.0

The client now requires .NET Framework 4.6.1 or .NET Standard 2.0. Earlier versions are no longer supported.

GitHub issue: #686

Microsoft.Diagnostics.Tracing.EventSource Dependency Dropped

Microsoft.Diagnostics.Tracing.EventSource dependency has been removed. It was an annoying dependency to have for some environments.

Source Linking

The library now supports source linking.

GitHub issue: #697

NuGet Source Packages

Source packages are now also distributed via NuGet.

CRL Checks for Server x.509 (TLS) Certificates

Added a TLS option to enforce CRL checks for server certificates.

No lock contention at consumer work service

Switched to a "thread-per-model" approach in the ConsumerWorkService.

  • ConsumerWorkService no longer has a constructor that takes a TaskScheduler
  • ConsumerWorkService.MAX_THUNK_EXECUTION_BATCH_SIZE has been removed
  • ConsumerWorkService no longer has the ExecuteThunk or RegisterKey methods
