v2.3

Add multisig contract as proxy owner (requires multisig for future contract upgrades), restore max supply to 1B, add mint function (up to max supply) and role, add burn function (each wallet can only burn their own tokens), and add recover function (burns tokens lost by accidental sends to contract address).

v2.2

Add EIP-3009 (Transfer with Authorization) to enable user withdrawals directly to their own web3 wallets. Skipped v2.1 to line up minor version (v2.2) with contract name (i.e. PRETokenV2).

v2.0

PRE Token (migrated)

v1.0

Original PRE Token before contract migration
