+   * Fix compilation warnings with IAR toolchain, on 32 bit platform.
+     Reported by rahmanih in #683
+   * Fix braces in mbedtls_memory_buffer_alloc_status(). Found by sbranden, #552.
+   * Added the macro MBEDTLS_X509_MAX_FILE_PATH_LEN that enables the user to
+     configure the maximum length of a file path that can be buffered when
+     calling mbedtls_x509_crt_parse_path().
+   * Fix redundant declaration of mbedtls_ssl_list_ciphersuites. Raised by

+     build to fail. Found by zv-io. Fixes #1651.
+   * Fix for redefinition of _WIN32_WINNT to avoid overriding a definition
+     used by user applications. Found and fixed by Fabio Alessandrelli.

+     versions later than 3.6. Fixes #1072

 Security
-   * Fix a bug in the X.509 module potentially leading to a buffer overread
-     during CRT verification or to invalid or omitted checks for certificate
-     validity. The former can be triggered remotely, while the latter requires
-     a non DER-compliant certificate correctly signed by a trusted CA, or a
-     trusted CA with a non DER-compliant certificate. Found by luocm on GitHub.
-     Fixes #825.
+   * Fix an issue in the X.509 module which could lead to a buffer overread
+     during certificate validation. Additionally, the issue could also lead to
+     unnecessary callback checks being made or to some validation checks to be
+     omitted. The overread could be triggered remotely, while the other issues
+     would require a non DER-compliant certificate to be correctly signed by a
+     trusted CA, or a trusted CA with a non DER-compliant certificate. Found by
+     luocm. Fixes #825.
+   * Fix the buffer length assertion in the ssl_parse_certificate_request()
+     function which led to an arbitrary overread of the message buffer. The
+     overreads could be caused by receiving a malformed message at the point
+     where an optional signature algorithms list is expected when the signature
+     algorithms section is too short. In builds with debug output, the overread
+     data is output with the debug data.
+   * Fix a client-side bug in the validation of the server's ciphersuite choice
+     which could potentially lead to the client accepting a ciphersuite it didn't
+     offer or a ciphersuite that cannot be used with the TLS or DTLS version
+     chosen by the server. This could lead to corruption of internal data
+     structures for some configurations.
 
 Bugfix
    * Add missing dependencies in test suites that led to build failures
      in configurations that omit certain hashes or public-key algorithms.
      Fixes #1040.
    * Add missing dependencies for MBEDTLS_HAVE_TIME_DATE and
-     MBEDTLS_VERSION_FEATURES in test suites. Contributed by Deomid Ryabkov.
-     Fixes #1299, #1475.
-   * Fix dynamic library building process with Makefile on Mac OS X. Fixed by
-     mnacamura.
+     MBEDTLS_VERSION_FEATURES in some test suites. Contributed by
+     Deomid Ryabkov. Fixes #1299, #1475.
+   * Fix the Makefile build process for building shared libraries on Mac OS X.
+     Fixed by mnacamura.
    * Fix parsing of PKCS#8 encoded Elliptic Curve keys. Previously Mbed TLS was
-     unable to parse keys with only the optional parameters field of the
-     ECPrivateKey structure. Found by jethrogb, fixed in #1379.
-   * Return plaintext data sooner on unpadded CBC decryption, as stated in
-     the mbedtls_cipher_update() documentation. Contributed by Andy Leiserson.

    * Fix overriding and ignoring return values when parsing and writing to
      a file in pk_sign program. Found by kevlut in #1142.
+   * Fix buffer length assertions in the ssl_parse_certificate_request()
+     function which leads to a potential one byte overread of the message
