+# Deprecation Notice
+
+**IMPORTANT - 2024-09-19** 
+
+This Spring module along with Client (v3) are being **deprecated** and will be **removed**. 
+
+It will be replaced by [**Client v4**](../conductor-clients/java/conductor-java-sdk/conductor-client), which offers improved features, better performance, 
+and other enhancements. 
+
+We strongly encourage all users to migrate to [**Client v4**](../conductor-clients/java/conductor-java-sdk/conductor-client) as soon as it becomes available. Expected release date: **2024-10-15**.
+
+## Deprecation Timeline
+
+- **Current Phase:** Client v3 is currently in maintenance phase and will receive critical fixes only.
+- **Final Phase Out:** Client v3 will be fully removed from the codebase on **2024-11-20**. The artifacts will remain available in Maven repo.
