+====================================

+  * The RSA_1.5 (RSA with PKCS#1 v1.5 padding) algorithm is now longer allowed by default. This means messages received
+  that use this algorithm will fail to decrypt.
+  * Several functions, classes and interfaces are now deprecated. Please check your code if you are using the API.
