Commit:

38b3a8d87f415325989626c4aa987aad0d3b4307

Changes:

• Renamed as follows:
  • Renamed all instances of "FORTH" to "HIFI"
  • Renamed all instances of "UNI" to "HIFI"
  • Renamed all instances of "Forth" to "Hifi"
  • Renamed all instances of "Uni" to "Hifi"
  • Renamed all instances of "forth" to "hifi"
  • Renamed all instances of "uni" to "hifi"
  • Renamed all instances of "Ampleforth" to "Hifi"
  • Renamed all instances of "Uniswap" to "Hifi Finance"
• Remove public visibility modifier from Hifi token constructor.
• Add @notice NatSpec tags to comments inside GovernorBravoInterfaces.sol to improve interface documentation.
• Fix typo in initialize(...) function comment in GovernorBravoDelegate.sol.

Commit:

4fafc8b8db71db51730c8587e3235846123962e6

Changes:

• Upgraded Solidity version to ^0.8.15, which also triggered the following changes:
  • Removed superfluous pragma experimental ABIEncoderV2; directives, since ABIEncoderV2 is activated by default since Solidity v0.8.
  • Fix outdated struct initialization in contracts/GovernorBravoDelegate.sol L129. This is similar to the latest Compound implementation in contracts/Governance/GovernorBravoDelegate L95, since Solidity disallows structs and arrays in memory or calldata if they contain nested mappings since v0.7.
  • Use view modifier for getChainId(...) and getChainIdInternal(...) functions instead of pure.
  • Remove superfluous public visibility tags from constructors.
  • Remove superfluous SafeMath.sol and refactor all affected lines to use standard Solidity arithmatic operations instead, since Solidity checks arithmatic operations by default since v0.8.
  • Use type(uint256).max instead of deprecated uint256(-1).
  • Use type(uint96).max instead of deprecated uint96(-1).
  • Use block.timestamp instead of deprecated now.

Commit:

ddded2ac84fdcee3e90a3dbcb3ca9a395b365cdd

Changes:

• Added Ampleforth token burn functionality to Hifi token by forking code directly from ampleforth/Forth/contracts/Forth.sol L134.

Commit:

29b9886ee7ba140f21029d8d2355bbca016e7445

Changes:

• Removed Uniswap emission schedule from Hifi token, which included the following changes:

  • Removed mintingAllowedAfter storage var.
  • Removed minimumTimeBetweenMints constant.
  • Removed mintCap constant.
  • Remove any require statements that depend on any removed variables.
  • Refactor mint(...) function implementation.

  Note: this commit includes a bug at hifi-finance/hifi-governance/contracts/Hifi.sol L119 that was fixed later on in 2f2bdf95b3bdeeeadb8bac01837847de689a6c43.

Commit:

e1dc7ddb22cf0b2944fbf5a8ce462dc1f7a1e91f

Changes:

• Add the MFT to HIFI token swap functionality. The code for the swap(...) function was not forked.

Commit:

c235e08f23e2c735966768752e1b84ffcc3fc249

Changes:

• Fixed bug in swap(...) at hifi-finance/hifi-governance/contracts/Hifi.sol L396 caused by trying to send burned MFT tokens to address(0), which is not allowed in the MFT token contract implementation.

Changes:

• Added a gas optimization at hifi-finance/hifi-governance/contracts/GovernorBravoDelegate.sol L127 by avoiding multiple SLOAD operations.
