OpenZeppelin 2.1.3
Bugfix release 馃悰 馃敡
A minor issue with SafeERC20.safeApprove was identified and reported independently by @nikeshnazareth (thanks once again!), this release contains the correspondig fix: #1647.
This bug has been present since v2.0.0. Updating to this latest version is recommended, but no immediate emergency action should be required for production code using affected versions, due to the low severity of the issue.
These independent reviews are a great way to keep our code secure and correct: we'll be making a push for a properly funded bug bounty during these next weeks to continue encouraging them. Stay tuned!
