Geth v1.10.7 is a maintenance release, mostly focusing on a few post-London polishes.

A few important notes to keep in mind:

• The return type for oldestBlock in eth_feeHistory was changed from decimal to hex. This is to conform to the updated spec that was released after Geth's London hard-fork release was already made. The input blockCount parameter was also updated, but there Geth will accept both hex and decimal to keep backward compatibility.
• The -miner.gastarget CLI flag was deprecated and is a noop. This flag is already a noop for networks running the London hard-fork, since it London miners only take into account the -miner.gaslimit flag. For non-London private networks and Geth forks, this might result in a gas bump depending on how the miners are configured.
• Docker builds were changed from DockerHub Automated Builds to offsite builds and manual pushes to DockerHub. At the same time, we've added support for multi-arch images, the original tags being the metadata image, linking a -amd64 and a -arm64 tags together. No changes are needed for docker users, but keep us posted if something strange happens. On the upside, Geth now has official arm64 docker images too.

Changes made:

• Change the oldestBlock return type in eth_feeHistory to hex, accept both decimal and hex as the block count (#23239, #23363).
• Cap max usable gas in eth_estimateGas better for 1559 transactions (#23309).
• When deploying multiple contracts via abigen, only parse the ABI once (#22583).
• Return maxFeePerGas for the gasPrice of pending transactions (#23345).
• Check cached blocks too when attempting to retrieve a header (#23299).
• Reject transactions imitated from non EOA accounts (#23303).
• Reduce allocations a bit while CPU mining ethash (#23199).
• Deprecate the -miner.gastarget CLI flag (#23213).
• Switch over to manual docker pushes (#23373).

Bugs fixed:

• Fix a nil pointer panic for certain abigen generated code due to missing context initialization (#23188).
• Fix nil pointer panic in certain automatic access list generation RPC API calls (#23225).
• Fix a regression that prevented clef from signing a legacy transaction (#23274).
• Fix a permission error during snapshot based pruning on Windows (#23370).
• Fix the marshaling of errors from the tracers (#23292).
