London upgrade and EIP-1559 Aug 5, 2021
The London upgrade activated at block 12,965,000 on August 5, 2021. Its best known change, EIP-1559, split fees into a base fee that is burned (destroyed) and an optional tip for validators. Fees became more predictable, and burning means ether supply can shrink when the network is busy.
