4.1.0:
    * ESPTREE implementation
    * CurveIdtc26gost34102012256paramSetB, CurveIdtc26gost34102012256paramSetC,
      CurveIdtc26gost34102012256paramSetD curve aliases
    * Forbid any later GNU GPL version autousage
      (project's licence now is GNU GPLv3 only)
    * Project now is go get-able and uses go.cypherpunks.ru namespace:
      go get go.cypherpunks.ru/gogost
      go get go.cypherpunks.ru/gogost/cmd/streebog{256,512}

4.0:
    * Backward incompatible change: all keys passing to encryption
      functions are slices now, not the fixed arrays. That heavily
      simplifies the library usage
    * Fix bug with overwriting IVs memory in gost28147.CFB*crypter
    * TLSTREE, used in TLS 1.[23], implementation
    * gost3410.KEK2012* can be used with any curves, not only 512-bit ones
    * gost3410.PrivateKey satisfies crypto.Signer interface
    * gost34112012* hashes satisfy encoding.Binary(Un)Marshaler
    * Streebog256 HKDF test vectors

3.0:
    * Multilinear Galois Mode (MGM) block cipher mode for
      64 and 128 bit ciphers
    * KDF_GOSTR3411_2012_256 KDF
    * 34.12-2015 64-bit block cipher Магма (Magma)
    * Additional EAC 28147-89 Sbox
    * 34.10-2012 TC26 twisted Edwards curve related parameters
    * Coordinates conversion from twisted Edwards to Weierstrass
      form and vice versa
    * Fixed gost3410.PrivateKey's length validation
    * Backward incompatible change: gost3410.NewCurve takes big.Int,
      instead of encoded integers
    * Backward incompatible Sbox and curves parameters renaming, to
      comply with OIDs identifying them:

    * Various additional test vectors
    * go modules friendliness

2.0:
    * 34.11-2012 is split on two different modules: gost34112012256 and
      gost34112012512
    * 34.11-94's digest is reversed. Now it is compatible with TC26's
      HMAC and PBKDF2 test vectors
    * gogost-streebog is split to streebog256 and streebog512
      correspondingly by analogy with sha* utilities
    * added VKO 34.10-2012 support with corresponding test vectors
    * gost3410.DigestSizeX is renamed to gost3410.ModeX because it is
      not related to digest size, but parameters and key sizes
    * KEK functions take big.Int UKM value. Use NewUKM to unmarshal
      raw binary UKM

1.1:
    * gogost-streebog is able to use either 256 or 512 bits digest size
    * 34.13-2015 padding methods
    * 28147-89 CBC mode of operation

1.0:
    Initial release.
