Geth v1.10.6 is a hotfix release. This resolves a consensus failure on the Ropsten testnet.

Users of Geth on the Ethereum mainnet must upgrade to this release before the London hard-fork activates to remain in consensus. Reminder: the London hard fork is scheduled to occur at block #12965000 on mainnet (~ August 4th, 2021).

More information about the Ropsten incident

During testing of the London hardfork on Ropsten, a consensus failure occurred in block 10679538, leading to a network split between OpenEthereum/Besu and Geth/Nethermind. The block contained a transaction from an account with enough funds to cover the effective fee, but too little funds for the transaction's maximum gas price. EIP-1559 mandates that such transactions should be rejected. Geth's implementation of EIP-1559 did not perform the check correctly and accepted the transaction.

For more information see PR #23244 and the post-mortem writeup.
