[2.0.0-beta2]

[1.5.3] (changes since 1.5.2)

  • Non-breaking improvements
    • CodeGen: support builds which use reference assemblies (#3753)

[2.0.0-beta1]

  • Breaking changes

    • Most packages are now targetting .NET Standard 2.0 (which mean they can be used from either .NET Framework or .NET Core 2.0).
      • These packages still target .NET Framework 4.6.1: Microsoft.Orleans.TestingSiloHost, Microsoft.Orleans.ServiceFabric, Microsoft.Orleans.OrleansTelemetryConsumers.Counters, Microsoft.Orleans.OrleansTelemetryConsumers.NewRelic and the PowerShell module.
    • Deprecated the Orleans Logging infrastructure.
      • Orleans now uses the Microsoft.Extensions.Logging abstractions package (MEL for short from now on).
      • The legacy Orleans' Logger abstraction is preserved as obsolete for backwards compatibility in a new Microsoft.Orleans.Logging.Legacy package, but it's just a wrapper that forwards to ILogger from MEL. It is recommended that you migrate to it directly.
      • This package also contains a provider for the new MEL abstraction that allows forwarding to ILogConsumer, in case the end-user has a custom implementation of that legacy interface. Similarly, it is recommended to rewrite the custom log consumer or telemetry consumer and implement ILoggerProvider from MEL instead.
      • The APM methods (TrackXXX) from Logger were separated into a new ITelemetryProducer interface, and it's currently only being used by Orleans to publish metrics. #3390
      • Logging configuration is no longer parsed from the XML configuration, as the user would have to configure MEL instead.
    • Created a Microsoft.Orleans.Core.Abstractions nuget package and moved/refactored several types into it. We plan to rev and do breaking changes to this package very infrequently.
    • NuGet package names were preserved for beta1, but several DLL filenames were renamed.
    • Runtime code generation was removed (Microsoft.Orleans.OrleansCodeGenerator package). You should use build-time codegen by installing the Microsoft.Orleans.OrleansCodeGenerator.Build package in the grain implementations' and interfaces' projects.
    • SiloHostBuilder and ClientBuilder are intended to replace the previous ways of initializing Orleans. They are not at 100% parity with ClusterConfiguration and ClientConfiguration so these are still required for beta1, but they will be eventually deprecated.
    • Note that when using SiloHostBuilder and ClientBuilder, Orleans will no longer scan every single assembly loaded in the AppDomain by default, and instead you need to be explicit to which ones you use by calling the AddApplicationPartXXX methods from each of the builders.
    • Silo membership (and its counterpart Gateway List Provider on the client) and MessagingOptions can be configured using the utilities in the Microsoft.Extensions.Options package. Before the final 2.0.0 release, the plan is to have everything moved to that configuration infrastructure.
    • Upgraded several dependencies to external packages that are .NET Standard compatible
    • Add support for Scoped services. This means that each grain activation gets its own scoped service provider, and Orleans registers IGrainActivationContext that can be injected into Transient or Scoped service to get access to activation specific information and lifecycle events #2856 #3270 #3385
    • Propagate failures in Grain.OnActivateAsync to callers #3315
    • Removed obsolete GrainState class #3167

  • Non-breaking improvements

    • Build-time codegen and silo startup have been hugely improved so that the expensive type discovery happens during build, but at startup it is very fast. This can remove several seconds to startup time, which can be especially noticeable when using TestCluster to spin up in-memory clusters all the time #3518
    • Add SourceLink support for easier debugging of nuget packages. You can now follow the following steps to debug Orleans code within your app: https://www.stevejgordon.co.uk/debugging-asp-net-core-2-source #3564
    • Add commit hash information in published assemblies #3575
    • First version of Transactions support (still experimental, and will change in the future, not necessarily back-compatible when it does). Docs coming soon.
    • Fast path for message addressing #3119
    • Add extension for one-way grain calls #3224
    • Google PubSub Stream provider #3210

[1.5.0]

  • Breaking changes

    • Bug fix: Azure storage providers now throw InconsistenStateException instead of StorageException when eTags do not match #2971
    • Automatically deactivate a grain if it bubbles up InconsistentStateException (thrown when there is an optimistic concurrency conflict when writing to storage) #2959
    • Upgraded minimum framework dependency to .NET 4.6.1 #2945
    • Support for non-static client via ClientBuilder (although static GrainClient still works but will be removed in a future version). You can now start many clients in the same process, even if you are inside a Silo #2822. There are a few differences though:
      • Several changes to SerializationManager, mainly to make it non-static #2592
        • When deserializing a GrainReference from storage, you might need to re-bind it to the runtime by calling grain.BindGrainReference(grainFactory) on it or you would get GrainReferenceNotBoundException when attempting to use it #2738
        • Removed RegisterSerializerAttribute (and corresponding static Register method for registering a custom serializer). If you were using that, please read https://dotnet.github.io/orleans/Documentation/Advanced-Concepts/Serialization.html#writing-custom-serializers for alternative ways to register your custom serializer #2941
    • Better serialization of Type values (but can cause compatibility issues if these were persisted by using the Serialziation Manager) #2952
    • Providers are now constructed using Dependency Injection. The result is that custom providers must have a single public constructor with either no arguments or arguments which can all be injected, or they need to be explicitly registered in the ServiceCollection. #2721 #2980
    • Replaced CacheSizeInMb setting with DataMaxAgeInCache and DataMinTimeInCache in stream providers #3126
    • Renamed the Catalog.Activation.DuplicateActivations counter to Catalog.Activation.ConcurrentRegistrationAttempts to more accurately reflect what it tracks and its benign nature #3130
    • Change default stream subscription faulting to false in EventHub and Memory stream providers, as is in other providers #2974
    • Allow IGrainWithGuidCompoundKey as implicit subscription grain, and sets the stream namespace as the grain key extension (subtle breaking change: previous to 1.5 IGrainWithGuidCompoundKey wasn't technically supported, but if you did use it, the grain key extension would have had a null string) #3011

[v1.4.1]

  • Improvements
    • Fix a cleanup issue in TestCluster after a failure #2734
    • Remove unnecessary service registration of IServiceProvider to itself, which improves support for 3rd party containers #2749
    • Add a timeout for socket connection #2791

    • Fix typos in format strings #2853
    • Fix null reference exception in simple queue cache. #2829

[v1.4.0]

  • Breaking changes

    • All grain instances and providers are constructed using the configured Dependency Injection container. The result is that all grains must have a single parameterless public constructor or single constructor with arguments which can all be injected. If no container is configured, the default container will be used. #2485

  • Known issues

    • When the silo starts up, it will register IServiceProvider in the container, which can be a circular reference registration when using 3rd party containers such as AutoFac. This is being addressed for 1.4.1, but there is a simple workaround for it at #2747
    • The build-time code generator required (and automatically added) a file named Properties\orleans.codegen.cs to the project where codegen was being ran. The new MSBuild targets no longer do that, so when upgrading a solution with a previous version of Orleans, you can safely delete this orleans.codegen.cs file from your grain projects.

        • Support for PostgreSql #2113
        • Memory Storage eTag enforcement less strict. #1885

        • Make IGrainFactory injectable #2192
        • Recover types from ReflectionTypeLoadException #2164
        • Moved Orleans Performance Counters into its own Telemetry Consumer. Now you need to explicitly register the OrleansPerfCounterTelemetryConsumer either by code or XML. More information in #2122 and docs will come later. Microsoft.Orleans.CounterControl can still be used to install the performance counters or you can use InstallUtil.exe OrleansTelemetryConsumers.Counters.dll to install it without depending on OrleansCounterControl.exe
