+## 2.3.1 - January 29, 2026
+
+### Enhancements
+
+* Added support for enforcing a minimum secret refresh interval (60 seconds) for Key Vault references during configuration refresh. When refresh is triggered, the provider will not re-fetch a secret if it was retrieved less than 60 seconds ago, avoiding excessive requests to Key Vault.

 ## 2.4.0-preview - January 13, 2026
