New Features

GPT-6.1 Sol is now the default model in the bundled and Amazon Bedrock catalogs. (#49318, #49339)
Amazon Bedrock supports multi-agent V2 and Ultra reasoning on compatible models; Bedrock Mantle also accepts AWS GovCloud regions. (#49345, #49813)
Sign in to MCP servers from an active terminal session with /mcp login <name>. (#49290)
Choose your microphone, speaker, and microphone input channels for voice conversations, with preferences saved locally. (#49437, #49836)
Daybreak is opt-in through --enable cli_daybreak or features.cli_daybreak=true; daybreak=true alone is insufficient. By default, controls and indicators are hidden, /daybreak is unavailable, and automatic Cyber routing is omitted—even for saved Daybreak threads. Saved preferences remain intact. Opt-in routing requires eligible ChatGPT sign-in, the OpenAI provider, and advertised model/program support. (#49856, #49858, #49859, #49861, #51207)
Select a Cyber access program per turn with codex exec --cyber-access-program or the TypeScript SDK’s cyberAccessProgram option. The explicit exec override remains available with cli_daybreak disabled and leaves the saved choice unchanged. (#49939, #51207)

Bug Fixes

Approved filesystem escalation can now grant broader write access while preserving denied reads and network restrictions. Background tasks retain their originating turn’s permissions. (#49353, #49880)
Explicit launch permissions survive terminal reconnects and new sessions, while implicit client settings no longer overwrite server or saved-thread web-search settings. (#49809, #49799)
Elevated Windows terminal sessions can start using an embedded server, and sandboxed PowerShell preserves relative paths beneath protected user profiles. (#49855, #49690)
Enter correctly submits buffered input after paste detection expires, including in Vim insert mode. (#49810)
Thread resume includes the latest committed history. Startup detects recoverable SQLite corruption earlier and preserves damaged databases as backups. (#49599, #49701)
Responses retries and WebSocket-to-HTTP fallback honor server retry guidance, reducing premature failures during overload. (#49441)

Documentation

Authentication guidance now accounts for keyring storage instead of implying credentials always reside in auth.json. (#49361)

Chores

Publishing an older alpha or hotfix no longer moves npm alpha tags backward. (#49704)
