* Support for DTLS 1.0 and 1.2 (RFC 6347).
API Changes
- * md_init_ctx() gained a new argument for optional hmac usage
+ * 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).
