+ <p> The Erlang scanner no longer accepts floating point
+ numbers in the input string. </p>

+ Own Id: OTP-10990</p>

+ <item>
+ <p>
+ When converting a faulty binary to a list with
+ unicode:characters_to_list, the error return value could
+ contain a faulty "rest", i.e. the io_list of characters
+ that could not be converted was wrong. This happened only
+ if input was a sub binary and conversion was from utf8.
+ This is now corrected.</p>

+ <item>
+ <p>The type <c>hook_function()</c> has been corrected in
+ <c>erl_pp</c>, the Erlang Pretty Printer. </p>
+ <p>The printing of invalid forms, e.g. record field
+ types, has also been fixed. It has been broken since
+ R16B. </p>
+ <p> (Thanks to Tom&#225;&#353; Janou&#353;ek.) </p>

+ Integrate elliptic curve contribution from Andreas
+ Schultz </p>
+ <p>
+ In order to be able to support elliptic curve cipher
+ suites in SSL/TLS, additions to handle elliptic curve
+ infrastructure has been added to public_key and crypto.</p>
+ <p>
+ This also has resulted in a rewrite of the crypto API to
+ gain consistency and remove unnecessary overhead. All OTP
+ applications using crypto has been updated to use the new
+ API.</p>
+ <p>
+ Impact: Elliptic curve cryptography (ECC) offers
+ equivalent security with smaller key sizes than other
+ public key algorithms. Smaller key sizes result in
+ savings for power, memory, bandwidth, and computational
+ cost that make ECC especially attractive for constrained
+ environments.</p>
