+## ✨ New Features
+
+### `minVersionForCollab` is now available on `IFluidDataStoreContext` ([#25130](https://github.com/microsoft/FluidFramework/issues/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.

+### Deprecate submitMessage on FluidDataStoreRuntime and MockFluidDataStoreRuntime ([#25332](https://github.com/microsoft/FluidFramework/issues/25332))
+
+As needed, access `submitMessage` via `IFluidDataStoreContext`/`IFluidParentContext`. See [#24406](https://github.com/microsoft/FluidFramework/issues/24406) for details.

+## Legacy API Changes
+
+### Wrapped errors preserved as `cause` property ([#25485](https://github.com/microsoft/FluidFramework/issues/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`).
