CODEX KILLS SESSION DROPOUTS, SDK TWINS SHIP API UPDATES

By RepoJournal · Filed · About OpenAI

A temporary WebSocket blip no longer terminates your entire process tree.

Codex just fixed the worst kind of invisible failure: exec-server sessions that survived connection loss were getting nuked on the client side anyway [1]. WebSocket reconnection now resumes dormant sessions instead of forcing a fresh start, which matters enormously for stdio MCP servers that were treating momentary network hiccups as permanent transport failures. On the plugin front, root-local marketplace installs now work correctly [2], and plugin telemetry got classified into real error buckets instead of dumping raw strings into analytics [3]. The exec layer also graduated to PathUri handling so cross-OS process execution works without path conversion disasters . Meanwhile both the Node SDK and Python SDK shipped v6.44.0 and v2.43.0 respectively [4] [5], both pulling in fresh OpenAPI spec alignments through Stainless automation.
