New Features

Default API model moved to gpt-5.2-codex. (#9188)
The codex tool in codex mcp-server now includes the threadId in the response so it can be used with the codex-reply tool, fixing #3712. The documentation has been updated at https://developers.openai.com/codex/guides/agents-sdk/. (#9192)
Headless runs now switch to device-code login automatically so sign-in works without a browser. (#8756)
Linux sandbox can mount paths read-only to better protect files from writes. (#9112)
Support partial tool calls rendering in tui

Bug Fixes

Alternate-screen handling now avoids breaking Zellij scrollback and adds a config/flag to control it. (#8555)
Windows correctly prompts before unsafe commands when running with a read-only sandbox policy. (#9117)
Config.toml and rules parsing errors are reported to app-server clients/TUI instead of failing silently. (#9182, #9011)
Worked around a macOS system-configuration crash in proxy discovery. (#8954)
Invalid user image uploads now surface an error instead of being silently replaced. (#9146)

Documentation

Published a generated JSON Schema for config.toml in docs/ to validate configs. (#8956)
Documented the TUI paste-burst state machine for terminals without reliable bracketed paste. (#9020)

Chores

Added Bazel build support plus a just bazel-codex helper for contributors. (#8875, #9177)
