Codex 0.141.0 improves remote work and plugin support

Codex 0.141.0-alpha.3 was released on June 16, 2026 as a pre-release, with only a short release note. The broader 0.141.0 release focused on safer remote execution and more reliable work environments. Remote execution now uses authenticated, end-to-end encrypted Noise relay channels, so commands sent to remote machines have stronger protected transport.

Cross-platform remote work now keeps the remote machine’s own working folder, shell, and file permission paths more consistently across app-server and exec-server boundaries. Selected executor plugins can turn on their stdio MCP servers for each thread, and plugin discovery now includes a created-by-me marketplace plus catalogs matched to the user’s authentication state. App-server clients gained ways to list child threads, track external-agent import results, and read or redeem rate-limit reset credits.

Realtime clients gained more control over speech input, how Codex responses enter conversations, and whether startup context is included. The release also reduced latency and memory use in large sessions with many tools, fixed plugin authentication routing, repaired stale Windows sandbox credentials, kept idle relays connected, supported enterprise proxy certificate signatures, and pinned SQLite to a version with a corruption fix.
