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.

Changing incorrect documentation in the header:
The public keys are X509 encoded. Private keys are just integers.
Adding some more edge cases:
These are mostly cases where the y coordinate is a special case.
Such special cases can lead to overflows if the point is normalized
during the ECDH compuation. A normalization is sometimes done in
precomputations.
Somewhat better comments: I.e. explain what the edge case is.
Removing unnecessary notes: Sometimes test vectors with labels are generated,
but not used because encoding can't handle the test vectors. Previously the
label would still end up in the notes section. This has been removed.

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.

Tests using the new test vectors will be added in another CL.
Changes:
AES-GCM has test vectors for modified tags, which were previously missing.
ECDSA has more test vectors for potential arithmetic errors.
There are no more random test vectors.
Webcrypto has a few test vectors with the bitcoin curve (since some libraries
want to add this).
DSA and ECDSA have more invalid test vectors with r,s = ((q-1)/2 or q-1).
This is motivated by some weak ElGamal implementation in beecrypt.
ECDH test vectors have some new files where the public key is just a point
using SEC 1 / X9.62 format.
All tests for ASN modifications are removed from ecdh_test.json, so that
this file has a more resonable size. These test vectors are included in
the files ecdh_curve_test.json.
EDDSA has a few more invalid test vectors for malformed signatures.
(I.e. the python implementation in the RFC has a small bug).
Adding test vectors for AES-CCM. (tested against BouncyCastle, which sort of
abuses the JCE interface)
There are some test vectors for RSA-PSS (so far tested with BouncyCastle and boringSSL)
More tests will be added when we have an idea what is actually being used.
