- Fixed crashes and stream drops caused by idle timeouts in HTTP/2 reverse proxy and SSE streams, and restored empty placeholders for missing cookies/TLS.
- Added support for the Incremental header (RFC 10036) to forward streaming responses immediately, with proper 501 handling and proxy status header.
- Improved TLS handshake performance, immediate Unix socket cleanup on reload, and corrected Set‑Cookie header handling and caddy fmt brace preservation.
