A new version of Erigon (on Polygon Fork) is available - v0.0.4.
If you are running erigon nodes on Mumbai, you need to upgrade to this version before the Delhi hardfork kicks in on 13th Dec 2022 (https://mumbai.polygonscan.com/block/countdown/29638656).
These are the instructions to upgrade Erigon on your nodes:
Upgrade Erigon to the latest version:
cd ~/erigon git pull git checkout v0.0.4 make erigon
Ensure that you are on the latest version:
./build/bin/erigon --version # It should return erigon version 0.0.4-bor-de539160
sudo service erigon restart
