 	- INCOMPATIBLE CHANGE: core protocol version 1.0.
-        - INCOMPATIBLE CHANGE: node sextions are now introduced
+        - INCOMPATIBLE CHANGE: node sections are now introduced
           with "node nodename", not "node = nodename".
+        - INCOMPATIBLE CHANGE: gvpectrl -g will now generate a single
+          keypair, while -G will try to generate all keypairs as before.
+        - openssl 1.0.2 is the latest supported openssl release,
+          openssl 1.1.0 is not supported at the moment as the work to
+          make it compatible to both versions is just too much. a switch
+          to openssl 1.1 or another library will be done in a future release.
+        - update examples to not generate keys centrally, but locally on each
+          node.
+        - add workaround for temporary/rare ENOBUFS condition.
         - while individual packets couldn't be replayed, a whole session
           could be replayed - this has been fixed by an extra key exchange.
+        - fix a delete vs. delete [] mismatch in the central logging function.
         - in addition to rsa key exchange and authentication, the handshake now
           adds a diffie-hellman key exchange (using curve25119) for perfect
           forward secrecy. mac and cipher keys are derived using HKDF.
         - rsa key sizes are now configurable and larger (default is 3072).
           correspondingly, the minimum mtu is no longer 296 but 576.
         - fixed a potential (unverified) buffer overrun on rsa decryption.
+        - new per-node low-power setting that tries to reduce cpu/network usage.
+        - router reconnects could cause excessive rekeying on other connections.
         - gvpectrl no longer generates all missing public keys, but
           only missing private keys. private keys are also put
           into the configured location.
         - the pid-file now accepts %s as nodename as elsewhere.
+        - switch to counter mode (only aes supported at the moment in
+          openssl). this gets rid of the need to generate a random iv,
+          is likely more secure (and, as a side effect, gets rid of
+          slow randomness generation. counter mode is often faster
+          then cbc mode as well, and packets are smaller).
         - no longer use RAND_bytes to generate session keys - you NEED
           a real source of entropy now (e.g. egd or /dev/random - see the
           openssl documentation).

           and will be merged.
         - a new directive "global" switches back to the global section
           of the config file.
-        - 12 random prefix bytes are now properly supported, leading to
-          a fully random IV.
-        - use aes with a random key in counter-mode to generate IVs,
-          for speed reasons (generating 12 random bytes with openssl can
-          take longer than encrypting and mac'ing a 1.5kb packet, and IVs
-          do not need to be cryptographically strong random numbers
-          (and in fact, shouldn't be)).
         - if-up scripts can now be specified with absolute paths.
         - new global option: serial, to detect configuration mismatches.
         - use HKDF as authentication proof, not HMAC or a plain hash
           (hint by Ilmari Karonen).
+        - during rekeying or connection establishments, hmac authentication
+          errors could occur and reset the connection. Transient hmac
+          authentication errors are now being ignored for 3 seconds.
+        - log the reason for a conneciton loss.
+        - use a (hopefully) constant time memcmp to compare internal secrets.
+        - fix a (harmless) errornous out of bounds stack read that would trigger
+          gcc's -fsanitize=address.
+        - bump old packet window size from 512 to 65536.
+        - update for big changes in openssl 1.1 API, wrap primitives
+          to make further changes easier.
+        - correctly check return values for openssl 1.0.0 and later.
+        - check for both public and private key file when deciding whether
+          to skip generating a key to avoid accidental overwrites.
