Rhone and Arve
Pre-release
Pre-release
v1.2.0-rc.2 -- Rhone and Arve -- is a release candidate for Mainnet Bellatrix. This release includes the Mainnet BELLATRIX_FOR_EPOCH as well as the tentative TERMINAL_TOTAL_DIFFICULTY. Additionally, it includes a small number of new Bellatrix tests as well as many R&D updates to withdrawals, light clients, and 4844/sharding.
Note: TERMINAL_TOTAL_DIFFICULTY assessed and potentially adjusted to better target Sept 15, 2022, please monitor for further refinement releases.
Note2: "Release candidate" (rc) distinction will be held on releases until after the mainnet Bellatrix upgrade. Once Mainnet runs the rule-set defined here a non-rc release will be made.
