HTTP v2.7.0

Diff since v2.6.7

HTTP.jl 2.7.0 adds opt-in request logging and configurable HTTP/1 header limits. It also fixes response reuse, HTTP/2 informational responses, Host ordering, and cookie handling.

Added

• HTTP.Handlers.logging_middleware provides opt-in request and error logs.
• HTTP.Transport accepts max_line_bytes and max_header_bytes; the default HTTP/1 line limit is now 64 KiB.
• setheader!, appendheader!, and removeheader! are aliases for the existing mutating header functions.
• The docs publish llms.txt and llms-full.txt with expanded API docstrings.

Fixed

• String response bodies can be reused. New pre-send checks reject spent BytesBody and CallbackBody values; bodyless responses remain valid.
• HTTP/2 accepts informational responses such as 103 Early Hints and correctly handles headers and trailers split across frames.
• HTTP/1 writes Host as the first header field.
• Adding request cookies uses semicolons and preserves separately stored cookie fields.
• Server error handling accepts any thrown Julia value, keeping error responses and access logs consistent.
• The connection pool honors server Keep-Alive timeout hints.
• Cookie Max-Age=0 expires the cookie.
• Per-request TLS configuration uses Reseau's copy constructor.

Julia 1.10 remains the minimum supported version.
