7.12.3 - 2026-06-23

Changed

• Adjusted guzzlehttp/psr7 version constraint to ^2.12.3

Security

• Treat IP and numeric cookie domains as exact-match-only (GHSA-g446-98w2-8p5w)

7.12.2 - 2026-06-23

Fixed

• Clamp out-of-range Max-Age so a very large value no longer overflows to an already-expired timestamp
• Use strict comparison in CookieJar conflict resolution so distinct numeric-string names don't overwrite
• Store a cookie whose Domain has a trailing dot on the origin host instead of silently discarding it
• Fix StreamHandler hard-failing on bracketed IPv6 literal hosts when force_ip_resolve is set
• Use strict cookie Path comparison so CookieJar::clear() with a numeric path keeps a distinct-path cookie
• Fixed cookie handling for falsey Domain, Max-Age, path, and name values
• Fixed decode_content handling for falsey string values
• Fixed deprecated request option values reaching built-in handlers before normalization

7.12.1 - 2026-06-18

Changed

• Adjusted guzzlehttp/psr7 version constraint to ^2.12.1

Fixed

• Reject proxy URLs with a malformed scheme in the cURL handlers instead of letting libcurl mishandle them

Security

• Reject HTTPS proxies when the installed libcurl lacks HTTPS-proxy support (GHSA-wpwq-4j6v-78m3)
• Reject dot-only cookie Domain attributes as match-all (GHSA-cwxw-98qj-8qjx)

7.12.0 - 2026-06-16

Added

• Added RequestOptions constants for curl, retries, and stream_context

Changed
