Andy Wooldridge merged a significant fix for the use-cache directive that removes blocking behavior during revalidation. The previous implementation was blocking stale data while fetching fresh data, then paradoxically serving…
The second merge was a backport by ijjk strengthening the RSC cache-busting parameters, originally from PR 92755.
