7.15.0 - 2026-07-17

Added

• Added Multiplexing::NONE support as a client, cURL multi handler, and conditional request option

Changed

• Adjusted guzzlehttp/psr7 version constraint to ^2.13
• Use locale-independent ASCII folding for all case normalization and comparison
• Bound cURL upload reads to the declared Content-Length
• Sanitize the cURL error text exposed through exception handler context
• Fail closed when a named cURL multi connection cap cannot be applied
• Reject the request-level CURLOPT_SHARE cURL option when named connection caps are configured
• Strengthen old-libcurl SOCKS isolation for raw CURLOPT_PRE_PROXY and opaque share handles
• Isolate HTTP proxy tunnels from opaque shared connection caches
• Trigger runtime deprecations for previously deprecated functionality in 7.1.0

Deprecated

• Deprecated Utils::jsonDecode() and Utils::jsonEncode() in favor of native JSON functions
• Deprecated passing CURLMOPT_PIPELINING in the cURL multi handler options array
• Deprecated passing CURLOPT_PROXYHEADER without cURL proxy header separation support

Fixed

• Defer cURL requests created from multi callbacks until native execution unwinds
• Fail synchronous waits from native cURL callbacks promptly instead of self-deadlocking
• Guard cURL multi handle removal against progress callbacks re-entering the handler
• Scope promise waits on the cURL multi handler to the awaited transfer
• Strip Content-Length and Transfer-Encoding when redirects discard the request body
• Stop re-applying the delay request option to followed redirects

7.14.2 - 2026-07-14

Security

• Prevent first-class and proxy URL credentials from reaching origins (GHSA-94pj-82f3-465w)
