 Documentation could always use help. Many things are completely undocumented,
 few things are documented well.

+Plans for 2017
+----------------------------------------
+
+It's an open question how many of these will end up being backported to 2.0.x,
+versus being features only in 2.1.x development snapshots.
+
+TLS 1.3
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The RFC process seems to be approaching consensus so hopefully there will be a
+final spec soon.
+
+The handshake differences are quite substantial, it's an open question how to
+implement that without overly complicating the existing TLS v1.0-v1.2 handshake
+code. There will also be some API changes to support 0-RTT data.
+
+This is a major project and probably will not start until later in the year.
+
+TLS Hardening/Testing
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Improve testing of TLS: leverage TLS-Attacker better, for example using custom
+workflows. Add tests using BoringSSL's hacked Go TLS stack.
+
+X509_Certificate Refactor
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The certificate classes use a type called Data_Store which ends up shoving
+everything (DN values, extension info, etc) into a single std::multimap<string,string>.
+This was a bad design. Instead the certificate type should contain X509_DN
+objects for the subject and issuer, an int value for the format version, and so on.
+The Data_Store type should be removed entirely.
+
+ASN.1 Redesign
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The current ASN.1 library (DER_Encoder/BER_Decoder) does make it
+roughly possible to write C++ code matching the ASN.1 structures. But
+it is not flexible enough for all cases and makes many unnecessary
+copies (and thus memory allocations) of the data as it works.
+
+It would be better to have a system that used (a simple subset of) ASN.1 to
+define the types as well as encoding/decoding logic. Then new types could be
+easily defined. This could also obviate the current code for handling OIDs, and
+allow representing the OIDs using the natural OID tree syntax of ASN.1.
+
+Another important feature will be supporting copy-free streaming decoding. That
+is, given a (ptr,len) range the decoding operation either returns an error
+(throws exception) or else the decoded object plus the number of bytes after ptr
+that contain the object, and it does so without making any allocations or
+copies.
+
+It will probably be easier to be consistently allocation free in machine
+generated code, so the two goals of the redesign seem to reinforce each other.
+
+Interface to PSK and SRP databases
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Adding support for databases storing encrypted PSKs and SRP credentials.
+
+Ed25519 signatures
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Used by many protocols these days including SSH and Tor.
+Probably will be done by importing from SUPERCOP or similar.
