 ### Breaking Changes
 
 - `SettingsManager` persistence semantics changed for SDK consumers. Setters now update in-memory state immediately and queue disk writes. Code that requires durable on-disk settings must call `await settingsManager.flush()`.
-- `AuthStorage` no longer uses direct constructor path convenience in SDK-facing usage. Use static factories (`AuthStorage.create(...)`, `AuthStorage.fromStorage(...)`, `AuthStorage.inMemory(...)`).
+- `AuthStorage` constructor is no longer public. Use static factories (`AuthStorage.create(...)`, `AuthStorage.fromStorage(...)`, `AuthStorage.inMemory(...)`). This breaks code that used `new AuthStorage(...)` directly.
