= mbed TLS 2.1.11 branch released xxxx-xx-xx
+Default behavior changes
+ * The truncated HMAC extension now conforms to RFC 6066. This means
+ that when both sides of a TLS connection negotiate the truncated
+ HMAC extension, Mbed TLS can now interoperate with other
+ compliant implementations, but this breaks interoperability with
+ prior versions of Mbed TLS. To restore the old behavior, enable
+ the (deprecated) option MBEDTLS_SSL_TRUNCATED_HMAC_COMPAT in
+ config.h. Found by Andreas Walz (ivESK, Offenburg University of
+ Applied Sciences).
+
+Security
+ * Fix implementation of the truncated HMAC extension. The previous
+ implementation allowed an offline 2^80 brute force attack on the
+ HMAC key of a single, uninterrupted connection (with no
+ resumption of the session).
+
Bugfix
* Fix assembly sequences in bn_mul.h and aesni.c to avoid segmentation
faults and errors when building for the 64-bit ILP32 ABI. Found and fixed

/**
+ * \def MBEDTLS_SSL_TRUNCATED_HMAC_COMPAT
+ *
+ * Fallback to old (pre-2.1.10), non-conforming implementation of the truncated
+ * HMAC extension which also truncates the HMAC key. Note that this option is
+ * only meant for a transitory upgrade period and is likely to be removed in
+ * a future version of the library.
+ *
+ * \warning The old implementation is non-compliant and has a security weakness
+ * (2^80 brute force attack on the HMAC key used for a single,
+ * uninterrupted connection). This should only be enabled temporarily
+ * when (1) the use of truncated HMAC is essential in order to save
+ * bandwidth, and (2) the peer is an Mbed TLS stack that doesn't use
+ * the fixed implementation yet (pre-2.1.10).
+ *
+ * Uncomment to fallback to old, non-compliant truncated HMAC implementation.
+ *
+ * Requires: MBEDTLS_SSL_TRUNCATED_HMAC
