 - Gateway/sessions: copy the oversized `sessions.json` to a rotation backup before the atomic rewrite instead of renaming the live store away, so a crash during rotation keeps the existing session-to-transcript mapping authoritative. Fixes #68229. Thanks @jjjojoj.
 - Providers/OpenAI-compatible: strip OpenAI-only Completions `store` from proxy payloads and allow `extra_body`/`extraBody` passthrough params for provider-specific request fields. Fixes #61826 and #69717.
 - Discord/subagents: preserve thread-bound completion delivery by keeping the requester-agent announce path primary and falling back to direct thread sends only when the announce produces no visible output. (#71064) Thanks @DolencLuka.
+- Discord/proxy: serialize proxied multipart attachment uploads with undici `FormData`, so Discord media sends work through configured REST proxies. (#71383) Thanks @TC500.
 - Browser/tool: give Chrome MCP existing-session manage calls a longer default timeout, pass explicit tool timeouts through tab management, and recover stale selected-page MCP sessions instead of forcing a manual reset. Thanks @steipete.
 - Browser/sandbox: clean up idle tracked tabs opened by primary-agent browser sessions, while preserving active tab reuse and lifecycle cleanup for subagents, cron, and ACP sessions. Fixes #71165. Thanks @dwbutler.
 - Plugins/Voice Call: reuse the webhook runtime across in-process plugin contexts, avoiding `EADDRINUSE` when agent tools or CLI commands run while the Gateway already owns the voice webhook port. Fixes #58115. Thanks @sfbrian.
