      Inserted as an enhancement for #1371
    * Add support for alternative CSR headers, as used by Microsoft and defined
      in RFC 7468. Found by Michael Ernst. Fixes #767.
-   * Update the Mbed Crypto submodule to version 0.1.0b2.
-   * Add unit tests for AES-GCM when called through mbedtls_cipher_auth_xxx()
-     from the cipher abstraction layer. Fixes #2198.

-  * Add an experimental build option, USE_CRYPTO_SUBMODULE, to enable use of
-    Mbed Crypto as the source of the cryptography implementation.
-  * Add an experimental configuration option, MBEDTLS_PSA_CRYPTO_C, to enable
-    the PSA Crypto API from Mbed Crypto when additionally used with the
-    USE_CRYPTO_SUBMODULE build option.
-  * Correct many misspellings. Fixed by MisterDA #2371.
-  * Provide an abstraction of vsnprintf to allow alternative implementations
-   for platforms that don't provide it. Based on contributions by Joris Aerts
-   and Nathaniel Wesley Filardo.
-  * Fix clobber list in MIPS assembly for large integer multiplication.
-    Previously, this could lead to functionally incorrect assembly being
-    produced by some optimizing compilers, showing up as failures in
-    e.g. RSA or ECC signature operations. Reported in #1722, fix suggested
-    by Aurelien Jarno and submitted by Jeffrey Martin.
