codex rust-v0.150.0

New Features

• Reference other Codex tasks with @ mentions, and ask agents to read, create, or message tasks from the terminal. (#40308, #40315)
• /copy now offers a picker for full responses, individual code blocks, and blockquotes. (#39997)
• Unnamed terminal tasks receive descriptive titles automatically, and /rename suggests an editable title based on the conversation. (#40492, #40495)
• Markdown links appear as clickable labels in supported terminals, with visible URLs retained elsewhere. (#40471)
• Bind shortcuts to cycle permission modes, and use . in Vim mode to repeat your last edit. (#39873, #40521)
• New Interrupt hooks can run commands or MCP handlers when an active top-level turn is interrupted. (#40511)

Bug Fixes

• Untrusted projects no longer supply project-level AGENTS.md instructions, and managed deny-read rules remain enforced after permission changes. (#39837, #40004)
• Improved credential redaction in app-server diagnostics, including provider, authentication refresh, and attestation fields. (#39993)
• Fixed remote MCP bearer-token lookup and required-server startup while preserving compatibility with older executors. (#39926, #39952, #39979)
• Fixed elevated Windows sandbox setup and launch aliases under Unicode user paths. (#39971, #40570)
• Prevented Unix shutdown hangs caused by detached processes retaining a terminal or full terminal output buffers. (#40460)
• Fixed conversation compaction and multi-agent compatibility for Amazon Bedrock models. (#39804, #39825)
