LINA [Linear] Token

Different versions of Solidity are used:
- Version used: ['>=0.4.24<0.8.0', '>=0.6.0<0.8.0', '>=0.6.2<0.8.0', '^0.6.0']
- >=0.6.2<0.8.0 (Address.sol#3)
- ^0.6.0 (AdminUpgradeabilityProxy.sol#3)
- >=0.6.0<0.8.0 (Context.sol#3)
- >=0.4.24<0.8.0 (Initializable.sol#4)
- >=0.6.0<0.8.0 (Ownable.sol#3)
- ^0.6.0 (Proxy.sol#3)
- ^0.6.0 (ProxyAdmin.sol#3)
- ^0.6.0 (UpgradeabilityProxy.sol#3)
Use one Solidity version.

Pragma version>=0.6.2<0.8.0 (Address.sol#3) is too complex
Pragma version^0.6.0 (UpgradeabilityProxy.sol#3) allows old versions
solc-0.6.8 is not recommended for deployment
Pragma version>=0.6.0<0.8.0 (Context.sol#3) is too complex
Pragma version>=0.6.0<0.8.0 (Ownable.sol#3) is too complex
Pragma version^0.6.0 (AdminUpgradeabilityProxy.sol#3) allows old versions
Pragma version>=0.4.24<0.8.0 (Initializable.sol#4) is too complex
Pragma version^0.6.0 (ProxyAdmin.sol#3) allows old versions
Pragma version^0.6.0 (Proxy.sol#3) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
