+
+#### Summary
+Legacy and deprecated delegate methods, as well as the old bridging layer, have been removed.
+When integrating via Objective-C, apps must now implement all methods of the public delegate protocols (you may provide empty implementations for callbacks you don't use).
+This change ensures a consistent API surface and removes ambiguity introduced by deprecated paths.
+
+Note: This change does not affect Swift integrations.
+Swift-based projects already conform to the complete delegate protocols and continue to work without modification.

+- `ucDidLoseConnection(_:)` → `didLoseConnection(_:)`
+- `uc(uc:willRetryConnectionNumber:in:)` → `uc(_:willRetryConnection:in:)`
+- `ucDidReestablishConnection(_:)` → `didReestablishConnection(_:)`
+
+**ACBClientPhoneDelegate**

+
+#### Migration Guide (Objective-C)
+- Ensure that all ObjC classes conforming to `ACBUCDelegate`, `ACBClientPhoneDelegate`, and `ACBClientCallDelegate` **implement all listed methods**.  
+  (Provide empty bodies for callbacks you don't use.)
+- Replace any legacy delegate names with the new equivalents shown above.
+- Remove any references to deprecated bridging layers and rely solely on the generated Swift-to-Objective-C headers.
