Main changes
On DSN side we have significantly improved performance related to announcement and retrieval by having more concurrency, more decoupled internal limits, ensuring to cache more things before giving up under high load, optimizing out some of the database writes that can be derived implicitly as well as resolving or temporarily hiding many of the DSN-related warnings to improve farming experience.
On the node side work continued on resolving farmer's dilemma by implementing new CLI flag that allows to opt-in into initial node sync from DSN rather than archival nodes. More tuning and securing of the implementation is necessary, but we're getting there.
