✨ New Features

minVersionForCollab is now available on IFluidDataStoreContext (#25130)

minVersionForCollab is now passed down from the ContainerRuntime to the Datastore layer where it is made available for SharedObject construction. DDSes may optionally consume this value and use it to determine which sets of feature flags should be enabled.

Public type changes

  • @fluidframework/datastore: `FluidDataStoreRuntime` - Exposes minVersionForCollab.
  • @fluidframework/runtime-definitions: `IFluidDataStoreContext` - Exposes optional member minVersionForCollab. See FluidDataStoreContext for an example implementation.
  • @fluidframework/test-runtime-utils: `MockFluidDataStoreContext`, `MockFluidDataStoreRuntime` - Exposes minVersionForCollab either via a getter or as a readonly field.

Note that the new implementations are optional fields and in some cases accept undefined. This is needed for layer compatibility, and in a future release these members will no longer be optional.

Legacy API Changes

Wrapped errors preserved as cause property (#25485)

IFluidErrorBase (internal basis for FluidFramework client errors) declares cause property matching ES2022 lib (whether targeted or not). When an error is wrapped, cause will be set to the originating error (which may or may not itself be an Error).
