What's New is an index, not a publisher: every entry below links to the vendor's own release notes, which are the authoritative source. Entries are labelled where they are hand-curated sample data, pre-releases, or drawn from a secondary source such as a developer blog.

Reuse: the summaries, labels and curation here are © What's New. Quote freely with attribution and a link back; wholesale republication of the corpus is not permitted — terms: https://whatsnew.fyi/terms. The vendors' own release notes remain their publishers'.

- **added** — Reference other Codex tasks with @ mentions, and ask agents to read, create, or message tasks from the terminal
- **added** — /copy now offers a picker for full responses, individual code blocks, and blockquotes
- **added** — Unnamed terminal tasks receive descriptive titles automatically, and /rename suggests an editable title based on the conversation
- **added** — Markdown links appear as clickable labels in supported terminals, with visible URLs retained elsewhere
- **added** — Bind shortcuts to cycle permission modes, and use . in Vim mode to repeat your last edit
- **added** — New Interrupt hooks can run commands or MCP handlers when an active top-level turn is interrupted
- **fixed** — Untrusted projects no longer supply project-level AGENTS.md instructions, and managed deny-read rules remain enforced after permission changes
- **fixed** — Improved credential redaction in app-server diagnostics, including provider, authentication refresh, and attestation fields
- **fixed** — Fixed remote MCP bearer-token lookup and required-server startup while preserving compatibility with older executors
- **fixed** — Fixed elevated Windows sandbox setup and launch aliases under Unicode user paths
- **fixed** — Prevented Unix shutdown hangs caused by detached processes retaining a terminal or full terminal output buffers
- **fixed** — Fixed conversation compaction and multi-agent compatibility for Amazon Bedrock models
