This minor update focuses on privacy and keeping things clean behind the scenes. It matters to anyone using the Codex CLI who wants to make sure their data isn't unnecessarily saved in temporary diagnostic files while the tool communicates with OpenAI's servers.
Fixes
- Keeping private data out of logs: Previously, when the tool used "WebSockets" (a technology that lets your computer talk to a server in real-time), it was saving the entire content of those messages—called "payloads"—into its troubleshooting files (trace logs). This release fixes that so your full message data is no longer written to those logs, protecting your privacy and keeping the log files from getting cluttered.
Breaking changes
No breaking changes in this release.
