v2.7.3

Release notes v2.7.3 🎉

This is a minor release

• Added update and remove operations to SparseMerkleTree data structure + significantly optimized add operation.

v2.7.2

Release notes v2.7.2 🎉

This is a minor release

• Added several missing typed functions to SetHelper and ArrayHelper contracts for consistency.

v2.7.1

Release notes v2.7.1 🎉

This is a minor release

• Added strictAdd() and strictRemove() functions to SetHelper library that check and revert if the inserted element already exists in the set/removed element doesn't exist in the set.

v2.7.0

Release notes v2.7.0 🎉

This is a new major release

This release mostly refactors the existing project structure and updates the required dependencies.

To recap, there are several new modules introduced:

• Vesting, Staking contracts to build efficient economic primitives.
• ZK-compatible SparseMerkleTree and IncrementalMerkleTree data structures.
• BlockGuard flash-loan protection mechanism.
• DiamondAccessControl, DimondERC721 contracts.
• UniswapV3Oracle to get historical UniswapV3 prices.
• PermanentOwnable with immutable owner funcitonality.

Some of the contracts got refactored and optimized:

• DecimalsConverter became more clear.
• DiamondOwnable is a standalone facet now.

Other changes:

• compound-rate-keeper, staking, and vesting got moved under finance folder.
• access-control folder got renamed to access.
• Vesting received an internal virtual function to release the funds.

And much more!
