February 2025 — Key feature delivered in httpwg/http-extensions: Cache Groups Documentation and Spec Clarifications. Refined language and examples in the cache groups draft, and standardized minimum implementation requirements by reducing mandatory support for groups and per-member characters from 128 to 32. This work incorporated reviewer feedback (artart) and aligned the draft with the HTTP extensions specification, improving clarity and adoption readiness. No major bugs were reported this period; the focus was on specification hygiene and documentation improvements. Two commits document the changes and maintain traceability.
