• Miners began bumping up the gas limit (12m now), which sparked some polemics about the tradeoff between state growth versus user fees. Higher gas limit resulted in safelow gas fees in the teens for the first time in weeks.

Eth2

• Nimbus (Nim) client update - up to spec, 10-50x processing speedup, splitting node and validator clients
