+This is an implementation of EdDSA in Java. Structurally, it is based on the ref10 implementation in SUPERCOP
+(see https://ed25519.cr.yp.to/software.html).
 
 There are two internal implementations:
-* A port of the radix-2^51 operations in ref10 - fast and constant-time, but only useful for Ed25519.
-* A generic version using BigIntegers for calculation - a bit slower and not constant-time, but compatible with any EdDSA parameter specification.

 ### 0.3.0
 
-- The library has been extensively profiled for contention issues in a multi-threaded environment.  The only remaining potential
-contention is in `EdDSANamedCurveTable.defineCurve()`, which will be rarely called.
-- The public constant for the curve name has returned as `ED_25519` and the curve specification has a public constant
-`ED_25519_CURVE_SPEC` to avoid repeated lookups when converting to and from encoded form for the public or private keys.
-- `GroupElement` is now completely immutable and all fields final to avoid the need for `synchronized` blocks over mutable fields.
-This required some new constructors and paths to construction.
-- `EdDSAPublicKeySpec.getNegativeA()` and `EdDSAPublicKey.getNegativeA()` now evaluate lazily, taking advantage of the 
-immutability of `GroupElement.negate()` which boosts the performance of the public key constructor when the key is just 
-being passed around rather than used.

-* Useful comments and tweaks were found in [the GNUnet implementation of Ed25519](https://gnunet.org/svn/gnunet-java/src/main/java/org/gnunet/util/crypto/) (based on k3d3's class).
-* [BloodyRookie](https://github.com/BloodyRookie) reviewed the code, adding many useful comments, unit tests and literature.
