Release v2.7.16

Release notes v2.7.16 🎉

This is a minor release

• Added U512 library for hyper-optimized on-chain BigInt arithmetic.
• Added ECDSA512 signature verification library which consumes 13.6 mln gas.

Release v2.7.15

Release notes v2.7.15 🎉

This is a patch release

ECDSA384

• Handled a double scalar multiplication edge case (fixes #125 and #126).

Release v2.7.12

Release notes v2.7.12 🎉

This is a minor release

• A collection of crypto libraries was added.
  • ECDSA verification over any 384-bit curve. Uses on-chain long arithmetic and consumes 9 million gas (the best in the industry).
  • RSASSA-PSS signature verification algorithm.

Release v2.7.11

Release notes v2.7.11 🎉

This is a minor feature release

• Added contains method to ArrayHelper to return bool whether the particular element is present in a sorted array.

Release v2.7.10
