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).
• Implemented 6-bit Strauss-Shamir precompute table which saved 75k gas.
• Fixed a modulo n signature validity comparison.

Release v2.7.14

Release notes v2.7.14 🎉

This is a minor feature release

• Added novel Cartesian Merkle Tree (CMT / Treaple) data structure reference implementation.
  • CMT can be used as a substitute for a Sparse Merkle Tree (SMT) when a hash function cost is low.
  • CMT consumes 2 times less storage than SMT.
  • With keccak256 CMT is 18% less expensive than SMT.
• Optimized ECDSA384 library signature verification to ~8.1 mln gas (previously ~9 mln).

Release v2.7.13

Release notes v2.7.13 🎉

This is a minor release

• Added ECDSA verification library on any 256-bit curves.

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

Release notes v2.7.10 🎉

This is a minor feature release

• Added return values to claimAll() and _distributeAll() functions in Staking and AbstractValueDistributor contracts.
• Modified MerkleWhitelisted interface to allow users to specify their own public functions.

Release v2.7.9

Release notes v2.7.9 🎉

This is a minor feature release

• Added claimAll() method to AbstractStaking contract.
• Added _distributeAllValue() method to AbstractValueDistributor contract.

Release v2.7.8

Release notes v2.7.8 🎉

This is a patch release

• Changed calldata to memory in MerkleWhitelisted contract to allow for calls within inheritance.

Release v2.7.7

Release notes v2.7.7 🎉

This is a minor feature release

• Added AVLTree library to store "key <> value" uint, address, and bytes32 pairs in ascending or descending order leveraging log(n) complexity.
• Added Iterator library to accommodate AVLTree in-order traversal.

Release v2.7.6
