here's the most accurate timeline for fusaka: - devnet 5 launch date -> when devnet 4 issues are addressed and new tests added - client releases for sepolia -> when/if there is a stable and clean devnet - holesky fork date -> when client releases for holesky are ready - sepolia fork date -> when holesky is stable and bugs in clients on holesky have been fixed - etc. projecting a date for all these milestones when the timeline for even the next *immediate* upgrade milestone is unclear makes NO SENSE!
