 = mbed TLS x.x.x branch released xxxx-xx-xx
 
+Bugfix
+   * Fix setting version TLSv1 as minimal version, even if TLS 1
+     is not enabled. Set MBEDTLS_SSL_MIN_MAJOR_VERSION
+     and MBEDTLS_SSL_MIN_MINOR_VERSION instead of
+     MBEDTLS_SSL_MAJOR_VERSION_3 and MBEDTLS_SSL_MINOR_VERSION_1. #664
+
+Changes
+   * Clarify the documentation of mbedtls_ssl_setup.
+
+= mbed TLS 2.7.1 branch released 2018-02-23
+
+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).

+   * Fix implementation of the truncated HMAC extension. The previous

+
+Bugfix
+   * Fix the name of a DHE parameter that was accidentally changed in 2.7.0.
+     Fixes #1358.
+   * Fix test_suite_pk to work on 64-bit ILP32 systems. #849
+   * Fix mbedtls_x509_crt_profile_suiteb, which used to reject all certificates
+     with flag MBEDTLS_X509_BADCERT_BAD_PK even when the key type was correct.
+     In the context of SSL, this resulted in handshake failure. Reported by
+     daniel in the Mbed TLS forum. #1351

+Security
+   * Fix a heap corruption issue in the implementation of the truncated HMAC
+     extension. When the truncated HMAC extension is enabled and CBC is used,
+     sending a malicious application packet could be used to selectively corrupt
+     6 bytes on the peer's heap, which could potentially lead to crash or remote
+     code execution. The issue could be triggered remotely from either side in
+     both TLS and DTLS. CVE-2018-0488
+   * Fix a buffer overflow in RSA-PSS verification when the hash was too large
+     for the key size, which could potentially lead to crash or remote code
+     execution. Found by Seth Terashima, Qualcomm Product Security Initiative,
+     Qualcomm Technologies Inc. CVE-2018-0487
+   * Fix buffer overflow in RSA-PSS verification when the unmasked data is all
+     zeros.
+   * Fix an unsafe bounds check in ssl_parse_client_psk_identity() when adding
+     64 KiB to the address of the SSL buffer and causing a wrap around.
+   * Fix a potential heap buffer overflow in mbedtls_ssl_write(). When the (by
      default enabled) maximum fragment length extension is disabled in the
      config and the application data buffer passed to mbedtls_ssl_write
      is larger than the internal message buffer (16384 bytes by default), the
      latter overflows. The exploitability of this issue depends on whether the
      application layer can be forced into sending such large packets. The issue
      was independently reported by Tim Nordell via e-mail and by Florin Petriuc
-     and sjorsdewit on GitHub. Fix proposed by Florin Petriuc in #1022. Fixes #707.

+   * Add a provision to prevent compiler optimizations breaking the time
+     constancy of mbedtls_ssl_safer_memcmp().
+   * Ensure that buffers are cleared after use if they contain sensitive data.
+     Changes were introduced in multiple places in the library.
+   * Set PEM buffer to zero before freeing it, to avoid decoded private keys
+     being leaked to memory after release.
+   * Fix dhm_check_range() failing to detect trivial subgroups and potentially
+     leaking 1 bit of the private key. Reported by prashantkspatil.
+   * Make mbedtls_mpi_read_binary() constant-time with respect to the input
+     data. Previously, trailing zero bytes were detected and omitted for the
+     sake of saving memory, but potentially leading to slight timing
+     differences. Reported by Marco Macchetti, Kudelski Group.
+   * Wipe stack buffer temporarily holding EC private exponent
+     after keypair generation.
+   * Fix a potential heap buffer over-read in ALPN extension parsing
+     (server-side). Could result in application crash, but only if an ALPN

- * \brief Diffie-Hellman-Merkle key exchange
+ * \brief Diffie-Hellman-Merkle key exchange.
  *
- *  Copyright (C) 2006-2015, ARM Limited, All Rights Reserved
+ * <em>RFC-3526: More Modular Exponential (MODP) Diffie-Hellman groups for
+ * Internet Key Exchange (IKE)</em> defines a number of standardized
+ * Diffie-Hellman groups for IKE.
+ *
+ * <em>RFC-5114: Additional Diffie-Hellman Groups for Use with IETF
+ * Standards</em> defines a number of standardized Diffie-Hellman
+ * groups that can be used.
+ *
+ * \warning  The security of the DHM key exchange relies on the proper choice
+ *           of prime modulus - optimally, it should be a safe prime. The usage
+ *           of non-safe primes both decreases the difficulty of the underlying
+ *           discrete logarithm problem and can lead to small subgroup attacks
+ *           leaking private exponent bits when invalid public keys are used
+ *           and not detected. This is especially relevant if the same DHM
+ *           parameters are reused for multiple key exchanges as in static DHM,
+ *           while the criticality of small-subgroup attacks is lower for
+ *           ephemeral DHM.
+ *
+ * \warning  For performance reasons, the code does neither perform primality
+ *           nor safe primality tests, nor the expensive checks for invalid
+ *           subgroups. Moreover, even if these were performed, non-standardized
+ *           primes cannot be trusted because of the possibility of backdoors
+ *           that can't be effectively checked for.
+ *
+ * \warning  Diffie-Hellman-Merkle is therefore a security risk when not using
+ *           standardized primes generated using a trustworthy ("nothing up
+ *           my sleeve") method, such as the RFC 3526 / 7919 primes. In the TLS
+ *           protocol, DH parameters need to be negotiated, so using the default
+ *           primes systematically is not always an option. If possible, use
+ *           Elliptic Curve Diffie-Hellman (ECDH), which has better performance,
+ *           and for which the TLS protocol mandates the use of standard
+ *           parameters.

+ * - RFC 7919 section A.1:  ffdhe2048
+ * - RFC 7919 section A.2:  ffdhe3072
+ * - RFC 7919 section A.3:  ffdhe4096
+ * - RFC 7919 section A.4:  ffdhe6144
+ * - RFC 7919 section A.5:  ffdhe8192
+ *
+ * The constants with suffix "_p" denote the chosen prime moduli, while
+ * the constants with suffix "_g" denote the chosen generator
+ * of the associated prime field.
+ *
+ * The constants further suffixed with "_bin" are provided in binary format,
+ * while all other constants represent null-terminated strings holding the
+ * hexadecimal presentation of the respective numbers.
+ *
+ * The primes from RFC 3526 and RFC 7919 have been generating by the following
+ * trust-worthy procedure:
+ * - Fix N in { 2048, 3072, 4096, 6144, 8192 } and consider the N-bit number
+ *   the first and last 64 bits are all 1, and the remaining N - 128 bits of
+ *   which are 0x7ff...ff.
+ * - Add the smallest multiple of the first N - 129 bits of the binary expansion
+ *   of pi (for RFC 5236) or e (for RFC 7919) to this intermediate bit-string
+ *   such that the resulting integer is a safe-prime.
+ * - The result is the respective RFC 3526 / 7919 prime, and the corresponding
+ *   generator is always chosen to be 2 (which is a square for these prime,
+ *   hence the corresponding subgroup has order (p-1)/2 and avoids leaking a
