 API Changes
+   * The library has been split into libmbedcrypto, libmbedx509, libmbedtls.
+     You now need to link to all of them if you use TLS for example.
    * All public identifiers moved to the mbedtls_* or MBEDTLS_* namespace.
      Some names have been further changed to make them more consistent.
