Main changes:
BigInteger encoding is now always a multiple of 2.
Comments try to be a bit more precise. This leads to a different
grouping of the test vectors.
All test vectors with result="acceptable" have at least one
flag.
New vectors:
AEGIS: adding test vectors with the same tag (basically just
answers the question: is AEGIS a hash?)
Test vectors from old versions of the cipher now have ciphertext.
I.e. both encrypting or decrypting should tell testers that they
are using old versions.
AES-CMAC: more test vectors with 128-bit tag.
DSA, ECDSA: better description of the ASN modifications (this reorders
the test vectors) and a few more ASN modifications
KWP: adding modified paddings
XDH: adding more edge cases, no longer using the same private key for multiple
test vectors.
RSA-PSS: adding more valid test vectors. The new test vectors have an edge case
message digest.

There are format changes:
* All test vector files contain a new field schema,
which points to a JSON schema definition
in the directory wycheproof/schema.
* More consistent type definition:
E.g. the field "type" in a testGroup is now describing the
type of the test the vectors are intended for. The type of
the test defines formatting (e.g. whether signatures use
P1363 encoding or ASN encoding) and the tested operation
(e.g. whether the test vectors signatures are primarily
are meant for verification or signature generation)
The test types will also be included in the documentation.
* More unified test vectors:
RSA-PKCS#1 v1.5 signature no longer have a field "padding".
* Added public and private keys in jwk format.
This is done when the jwk format is defined and
where the key format is not part of the test.
Additional test vectors:
* Added vectors for edge cases that can occur
in ECDH computations with projective or Jacobian
coordinates. In particular this implements a detection for the
attack in "Zero-Value Point Attacks on Elliptic Curve Cryptosystem"
by T.Akishita and T Takagi, ISC 2003
* Added more edge cases for Xdh.
* Added more test cases for ASN parsing (e.g. high number tags)
* Added test vectors for CVE-2017-18330 to CCM and EAX.
* Added more edge cases for poly1305
* Added test vectors for HKDF.
* Removed some duplicates in the test vectors.
