Deployments of Zstandard, or "zstd", can use different window sizes to limit memory usage during compression and decompression. Some browsers and user agents limit window sizes to mitigate memory usage concerns, causing interoperability issues. This document updates the window size limit in RFC8878 from a recommendation to a requirement in HTTP contexts.
