We have released Cipher 2.6.2 and Sapphire 0.3.1 for MAINNET . Any node operators running Cipher and/or Sapphire on MAINNET please update your Cipher/Sapphire ParaTime node configuration to add the new version of the ParaTime and restart your node in preparation of the upcoming MAINNET upgrade. See the updated MAINNET network parameters page for the link to the new ORC: Mainnet | Oasis Network Documentation. Thanks!
