+## 🌳 SharedTree DDS Changes
+
+### Fix Tree.key and Tree.parent for Unhydrated nodes after edits ([#24708](https://github.com/microsoft/FluidFramework/issues/24708))
+
+In some cases, editing [Unhydrated](https://fluidframework.com/docs/api/fluid-framework/unhydrated-typealias) nodes could result in incorrect results being returned from [Tree.key](https://fluidframework.com/docs/data-structures/tree/nodes#treekey) and [Tree.parent](https://fluidframework.com/docs/data-structures/tree/nodes#treeparent). This has been fixed.

+
+### Name collisions from structurally named schema now error ([#24707](https://github.com/microsoft/FluidFramework/issues/24707))
+
+It is legal to have multiple [TreeNodeSchema](https://fluidframework.com/docs/api/fluid-framework/treenodeschema-typealias) with the same name so long as they are not used together in the same tree. Using different schema with the same name when building otherwise identical [structurally named](https://fluidframework.com/docs/api/fluid-framework/schemafactory-class#schemafactory-remarks) in the same [SchemaFactory](https://fluidframework.com/docs/api/fluid-framework/schemafactory-class) is not valid, however. Previously doing this would not error, and instead return the first structurally named schema with that name. Now this case throws an informative error:
+
+```typescript
+const factory = new SchemaFactory(undefined);
+class Child1 extends factory.object("Child", {}) {}
+class Child2 extends factory.object("Child", {}) {}
+
+const a = factory.map(Child1);
+
+// Throws a UsageError with the message:
+// "Structurally named schema collision: two schema named "Array<["Child"]>" were defined with different input schema."
+const b = factory.array(Child2);
+```

+
+### Defaulted identifier fields on unhydrated nodes are now enumerable ([#24739](https://github.com/microsoft/FluidFramework/issues/24739))
+
+Previously, there was a special case for defaulted [identifier](https://fluidframework.com/docs/api/fluid-framework/schemafactory-class#identifier-property) fields on unhydrated nodes where they were not enumerable. This special case has been removed: they are now enumerable independent of hydration status and defaulting.
