We just released a bugfix release for Windsor, version 3.2.1.

It fixes a problem some users encountered, when CallContext scoped lifestyle is used in certain cross-AppDomain contexts. It specifically affected users of some testing framework or NServiceBus when deployed to Azure. The bug would manifest itself with the following exception:

SerializationException — Type is not resolved for member "Castle.MicroKernel.Lifestyle.Scoped.CallContextLifetimeScope+SerializationReference,Castle.Windsor, Version=3.2.0.0, Culture=neutral, PublicKeyToken=407dd0808d44fbdc"

The package is available on NuGet now.
