+Removals
+   * Remove the TLS 1.0, TLS 1.1 and DTLS 1.0 support by removing the following
+     deprecated library constants: MBEDTLS_SSL_PROTO_TLS1,
+     MBEDTLS_SSL_PROTO_TLS1_1, MBEDTLS_SSL_CBC_RECORD_SPLITTING,
+     MBEDTLS_SSL_CBC_RECORD_SPLITTING_ENABLED,

+     MBEDTLS_SSL_FALLBACK_SCSV, MBEDTLS_SSL_FALLBACK_SCSV_VALUE,
+     MBEDTLS_SSL_IS_FALLBACK, MBEDTLS_SSL_IS_NOT_FALLBACK, and functions:
+     mbedtls_ssl_conf_cbc_record_splitting(),
+     mbedtls_ssl_get_key_exchange_md_ssl_tls(), mbedtls_ssl_conf_fallback().
+     Fixes #4286.

+Remove suport for TLS 1.0, 1.1 and DTLS 1.0
+-------------------------------------------
+
+This change affects users of the TLS 1.0, 1.1 and DTLS 1.0 protocols.
+
+The versions of (D)TLS that are being removed are not as secure as the latest
+versions. Keeping them in the library creates opportunities for misconfiguration
+and possibly downgrade attacks. More generally, more code means a larger attack
+surface, even if the code is supposedly not used.
+
+The migration path is to adopt the latest versions of the protocol.
