Globally manages the transition between environments at the epoch boundary

The epoch of the upcoming_environments

Anticipated replacement for environments at the next epoch

This is None during most of an epoch, and only Some around the boundaries (at the end and beginning of an epoch). More precisely, it starts with the cache preparation phase a few hundred slots before the epoch boundary, and it ends with the first rerooting after the epoch boundary.

programs_to_recompile: Vec<(Pubkey, Arc<ProgramCacheEntry>)>

List of loaded programs which should be recompiled before the next epoch (but don’t have to).
