+## Manual Approval TransferManager
+* Removed `0x0` check for the `_from` address to `ManualApprovalTransferManager`. This allows for the Issuer/Transfer Agent to approve a one-off mint of tokens that otherwise would not be possible. 
+* Changed the version of `ManualApprovalTransferManagerFactory` from `1.0.0` to `2.0.1`.

 * All permissions are denied if no permission manager is active.
 * Generalize the STO varaible names and added them in `ISTO.sol` to use the common standard in all STOs.
 * Generalize the event when any new token get registered with the polymath ecosystem. `LogNewSecurityToken` should emit _ticker, _name, _securityTokenAddress, _owner, _addedAt, _registrant respectively. #230  
-* Change the function name of `withdraPoly` to `withdrawERC20` and make the function generalize to extract tokens from the ST contract. parmeters are contract address and the value need to extract from the securityToken.
