KokoToken._approve(address,address,uint256).owner (contracts/KokoToken.sol#284) shadows:

KokoToken.constructor(address,address,address,address,address,address,address,address)._development (contracts/KokoToken.sol#39) lacks a zero-check on :

Check that the address is not zero.

KokoToken.teamRelease() (contracts/KokoToken.sol#90-112) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(releaseStartDate <= block.timestamp,token: release not started) (contracts/KokoToken.sol#92-95)
- require(bool,string)(block.timestamp >= lastTeamRelease + 7776000,token: let the quarter over) (contracts/KokoToken.sol#104-107)
Avoid relying on block.timestamp.
