   * Support for DTLS 1.0 and 1.2 (RFC 6347).
 
 API Changes
+   * md_init_ctx() is deprecated in favour of md_setup(), that adds a third
+     argument (allowing memory savings if HMAC is not used)
+   * Removed individual mdX_hmac and shaX_hmac functions (use generic
+     md_hmac functions from md.h)
+   * Change md_info_t into an opaque structure (use md_get_xxx() accessors).
    * Some constness fixes
    * Signature of mpi_mul_mpi() changed to make the last argument unsigned
    * Remove the PBKDF2 module (use PKCS5).
