 ### Fixes
 
 - Exec/YOLO: stop rejecting gateway-host exec in `security=full` plus `ask=off` mode via the Python/Node script preflight hardening path, so promptless YOLO exec once again runs direct interpreter stdin and heredoc forms such as `node <<'NODE' ... NODE`.
-- OpenAI Codex: normalize legacy `openai-completions` transport overrides on default OpenAI/Codex hosts back to the native Codex Responses transport while leaving custom proxies untouched. (#45304) Thanks @dyss1992.
+- OpenAI Codex: normalize legacy `openai-completions` transport overrides on default OpenAI/Codex and GitHub Copilot-compatible hosts back to the native Codex Responses transport while leaving custom proxies untouched. (#45304, #42194) Thanks @dyss1992 and @DeadlySilent.
 - Anthropic/plugins: scope Anthropic `api: "anthropic-messages"` defaulting to Anthropic-owned providers, so `openai-codex` and other providers without an explicit `api` no longer get rewritten to the wrong transport. Fixes #64534.
 - fix(qqbot): add SSRF guard to direct-upload URL paths in uploadC2CMedia and uploadGroupMedia [AI-assisted]. (#69595) Thanks @pgondhi987.
 - fix(gateway): enforce allowRequestSessionKey gate on template-rendered mapping sessionKeys. (#69381) Thanks @pgondhi987.
