Added

• Add görli testnet ENS registry to the known registries (#3252)
• Add auto-reconnect option for Websockets (#3092, #1085, #1391, #1558, #1852, #1646)

Changed

• Ensure '0x' prefix is existing for Accounts.sign and Accounts.privateKeyToAccount (#3041)
• Repository cleanup (#3443)
  • Removed old docs/_build folder
  • Removed old bower and meteor artifacts
  • Moved logo assets to own folder
  • Moved github assets to own folder
  • Remove @types/node from (non-dev) dependency tree (#3965, #3227)
• Please note: Geth v1.9.12 contains a breaking change for eth_call that will not default to your first account anymore if from is not set. If a sender is not explicitly defined, the eth_call will be executed from address(0). (#3467)
  • This was done to avoid the same input behaving differently in different environments. You should never do eth_call without explicitly setting a sender.
  • This means that if you're calling view methods that refer to a msg.sender without explicitly setting a from address in your request options, you may see unexpected behavior.
  • In web3.js, the from address can be specified on a per-call basis or by setting the defaultAccount property.
