Human Factors
We departed ZZZ with incorrect release. Both the Captain and I missed that we were on release 2. There was a re-route which ATC had to read to us. The Dispatcher thought he published release 2 before the Captain signed release 1. He was mistaken. Captain signed for release 1 three minutes before the Dispatcher submitted release 2. The Captain and I should have caught the error when the Final Weight Manifest was reviewed. This was my third flight after being off for 6 months because of COVID-19.
Air carrier First Officer reported the flight departed with incorrect release documentation. The First Officer referenced not having flown in the last 6 months due to the COVID-19 pandemic.
