+= PolarSSL 2.0 branch
 
 Features
   * Support for DTLS 1.0 and 1.2 (RFC 6347).
 
 API Changes
+   * Headers are now found in the 'mbedtls' directory (previously 'polarssl').
+   * Change SSL_DISABLE_RENEGOTIATION config.h flag to SSL_RENEGOTIATION
+     (support for renegotiation now needs explicit enabling in config.h).
+   * Remove compat-1.2.h (helper for migrating from 1.2 to 1.3).
+   * Remove openssl.h (very partial OpenSSL compatibility layer).
    * net_connect() and net_bind() have a new 'proto' argument to choose
      between TCP and UDP, using the macros NET_PROTO_TCP or NET_PROTO_UDP.
    * ssl_set_bio() now requires that p_send == p_recv.
    * ssl_set_bio() is deprecated in favor of ssl_set_bio_timeout().
 
+Changes
+   * Support for receiving SSLv2 ClientHello is now disabled by default at
+     compile time.
