YOLOv3 & Berlin client updates

• Estimated Berlin blocks & timeline Ropsten will be forked around March 10th.

• London timing — Start discussing London EIP soon and get a consensus in the next 2–3 meetings.
• Eth1-Eth2 merge team shared some roadmap but will produce more documents for Eth1 clients to describe what to be expected with Eth1 chain post-merge.
• One of the ideal times for merge was the time of difficulty bomb hitting the Eth1 chain. So, Vitalik suggested pushing the bomb for about 6 months & add the Difficulty bomb as a part of every upgrade till the Eth1-Eth2 merge.
• Backwards-incompatibly changing and/or removing EVM features — Vitalik proposed a bunch of features to be removed from EVM in the upcoming upgrades. Out of which removing ‘refund’ can be targeted to London. It will affect Gas token applications.

Eth1.0 Clients update

• Geth — Marljeh (v1.9.25)
• OpenEthereum — v3.1.1
• Besu —21.1.0-RC2. Distributions and maven artifacts have been moved off of binary. Support “eth” field in ENR records.

• TurboGeth — 2021.02.03-alpha
• Nethermind —v1.10.23. Fix to tx pool filtering for xDAI validators. All ready for the Berlin hard fork planned for April 14th.
