New Features

  • Remote plugins are now enabled by default, with richer catalog rows, npm marketplace sources, and visible remote/local versions.
  • Codex can route authentication and Responses API traffic through macOS and Windows system proxies, including PAC and WPAD configurations.
  • Added codex remote-control pair for generating manual pairing codes from a running daemon.
  • Added Amazon Bedrock GPT-5.6 Sol, Terra, and Luna models, with first-class support for max reasoning effort.
  • MCP tools now use tool search by default, and ChatGPT-hosted MCP servers can explicitly use session authentication.
  • App-server clients can inspect environments, list descendant threads, and fork history through a specific turn.

Bug Fixes

  • Fixed Windows ConPTY input handling for line endings and backspace, plus sandbox credential retry edge cases.
  • Fixed stale TUI safety prompts and cancelled reviews that could leave MCP startup appearing busy.
  • Improved recovery when exec servers are temporarily offline and prevented remote-control token refresh retry storms.
  • Preserved trailing realtime transcript text and terminal rollout events during shutdown.
  • Improved incremental WebSocket request success by ignoring response metadata during comparisons.
  • Reduced installer failures from GitHub API rate limits by reusing release metadata.

Documentation

  • Documented UUID7 thread and turn IDs, plus recommended remote-executor integration-test workflows.

Chores

  • Updated OpenSSL, Hono, fast-uri, quick-xml, and crossbeam-epoch to address security advisories.
