Month: 2025-10 – httpwg/http-extensions. Focused on delivering comprehensive documentation improvements for resumable uploads to reduce ambiguity and improve interoperability. Implemented a series of clarifications and guidance around negotiation, lifecycle handling, and edge cases, with emphasis on Accept-Patch requirements in OPTIONS, conditional Upload-Limit when Accept-Patch is present, the interaction between 100 Continue and 104 Upload Resumption, and explicit behavior when upload state is lost. Also clarified client handling of 104 in relation to 100-continue expectations, defined 'prior knowledge', proposed post-completion resource verification alternatives, and reinforced that servers must not omit 100 Continue when 104 is sent. A new alternative to keeping the upload resource available after completion was introduced.

September 2025: Delivered targeted documentation improvements for resumable uploads in httpwg/http-extensions, with clarifications on compatibility with HTTP uploads, URI uniqueness policy, max-size behavior, response source after completion, and fallback to conventional uploads on interruption. These changes reduce integration risk and accelerate adoption by providing clearer guidance and reducing ambiguity across the resumable upload workflow.

February 2025 focused on modernizing URLSession in swift-foundation by introducing an opt-in HTTP loader and deprecating legacy features, positioning the project for Network framework-based improvements on Darwin and reducing long-term maintenance costs.
