+API changes
+   * mbedtls_ssl_conf_export_keys_ext_cb() and
+     mbedtls_ssl_conf_export_keys_cb() have been removed and
+     replaced by a new API mbedtls_ssl_set_export_keys_cb().
+     Raw keys and IVs are no longer passed to the callback.
+     Further, callbacks now receive an additional parameter
+     indicating the type of secret that's being exported,
+     paving the way for the larger number of secrets
+     in TLS 1.3. Finally, the key export callback and
+     context are now connection-specific.

+SSL key export interface change
+-------------------------------
+
+This affects users of the SSL key export APIs:
+```
+    mbedtls_ssl_conf_export_keys_cb()
+    mbedtls_ssl_conf_export_keys_ext_cb()
+```
+
+Those APIs have been removed and replaced by the new API
+`mbedtls_ssl_set_export_keys_cb()`. This API differs from
+the previous key export API in the following ways:
+
+- It is no longer bound to an SSL configuration, but to an
+  SSL context. This allows users to more easily identify the
+  connection an exported key belongs to.
+- It no longer exports raw keys and IV.
+- A secret type parameter has been added to identify which key
+  is being exported. For TLS 1.2, only the master secret is
+  exported, but upcoming TLS 1.3 support will add other kinds of keys.
+- The callback now specifies a void return type, rather than
+  returning an error code. It is the responsibility of the application
+  to handle failures in the key export callback, for example by
+  shutting down the TLS connection.
+
+For users which do not rely on raw keys and IV, adjusting to the new
+callback type should be straightforward - see the example programs
+programs/ssl/ssl_client2 and programs/ssl/ssl_server2 for callbacks
+for NSSKeylog, EAP-TLS and DTLS-SRTP.
+
+Users which require access to the raw keys used to secure application
+traffic may derive those by hand based on the master secret and the
+handshake transcript hashes which can be obtained from the raw data
+on the wire. Such users are also encouraged to reach out to the
+Mbed TLS team on the mailing list, to let the team know about their
+use case.
