[6.0.1] - 2026-03-16

Changed

• Exclude test files from gem package, reducing gem size by 50% (from 175 KB to 87 KB).

[6.0.0] - 2026-03-16

Changed

• Merged http-form_data gem into the main http gem. The HTTP::FormData module (including Part, File, Multipart, Urlencoded, and CompositeIO) is now shipped directly with http instead of being a separate dependency. The public API is unchanged.

Fixed

• Inflater no longer raises Zlib::BufError when a response declares Content-Encoding: gzip (or deflate) but the body is not valid compressed data. This commonly occurred when following redirects with auto_inflate enabled, because the redirect response had a Content-Encoding header but a non-compressed body. (#621)
• Persistent connections now auto-flush unread response bodies before sending the next request, instead of raising StateError. Bodies up to 1 MiB are drained transparently; larger bodies cause the connection to close and reopen. This prevents the silent body clobbering described in #371, where an unread response body would return "" after a subsequent request. (#371)
• Response#content_length now handles duplicate Content-Length headers per RFC 7230 Section 3.3.2. When all values are identical, they are collapsed into a single valid value. When values conflict, nil is returned instead of raising TypeError. (#566)
• HTTP 1xx informational responses (e.g. 100 Continue) are now transparently skipped, returning the final response. This was a regression introduced when the parser was migrated from http-parser to llhttp. (#667)
• Redirect loop detection now considers cookies, so a redirect back to the same URL with different cookies is no longer falsely detected as an endless loop. Fixes cookie-dependent redirect flows where a server sets a cookie on one hop and expects it on the next. (#544)
• Per-operation timeouts (HTTP.timeout(read: n, write: n, connect: n)) no longer default unspecified values to 0.25 seconds. Omitted timeouts now mean no timeout for that operation, matching the behavior when no timeout is configured at all. (#579)
• Per-operation timeout handler now correctly handles :wait_writable from read_nonblock and :wait_readable from write_nonblock on SSL sockets during TLS renegotiation. Previously these symbols were returned as data instead of being waited on. (#358)
• Persistent sessions now follow cross-origin redirects instead of raising StateError. HTTP.persistent returns an HTTP::Session that pools one HTTP::Client per origin, so redirects to a different domain transparently open (and reuse) a separate persistent connection. Cookie management is
