+## Aspire 13.2.1
+
+Aspire 13.2.1 is a patch release focused on the TypeScript AppHost SDK.
+
+### Breaking changes in the TypeScript AppHost SDK
+
+The following TypeScript AppHost APIs were renamed. Update any affected `apphost.ts` files accordingly:
+
+| Previous name | New name | Notes |
+| --- | --- | --- |
+| `runAsExistingFromParameters(name, resourceGroup)` | `runAsExisting(name, { resourceGroup })` | Name change plus positional → options object. |
+| `publishAsExistingFromParameters(name, resourceGroup)` | `publishAsExisting(name, { resourceGroup })` | Name change plus positional → options object. |
+| `withConnectionPropertyValue(name, value)` | `withConnectionProperty(name, value)` | Unified API for string/reference values. |
+| `withParameterBuildArg(name, parameter)` | `withBuildArg(name, parameter)` | Renamed to the unified `withBuildArg` surface. |
+
+<Aside type="note">
+  `withConnectionPropertyValue` is restored as a compatibility alias in the generated SDKs, so it is not a runtime SDK break. However, the updated `apphost.ts` samples have been migrated to use `withConnectionProperty`.
+</Aside>
