25Claude in Chrome is generally available
26v2.1.198
27
28The Chrome integration is out of preview for everyone on a direct Anthropic plan. Claude Code drives your browser through the Claude in Chrome extension: it opens tabs, clicks through pages, fills forms, reads console logs, and shares your login state, so it can test the app it builds without you switching contexts.

32Subagents run in the background by default
33v2.1.198
34
35Claude now keeps working while subagents run and picks up their results when they finish, instead of pausing the conversation to wait. Claude still runs a subagent in the foreground when it needs the result before continuing, and background subagents surface every permission prompt in your main session. Pin a subagent's behavior with the `background` frontmatter field.

39Claude Desktop on Linux
40Desktop
41
42The Claude desktop app is now available on Ubuntu 22.04+ and Debian 12+ in beta, on x86\_64 and arm64. You get the same Chat, Cowork, and Claude Code experience as macOS and Windows: parallel sessions, visual diff review, an integrated terminal and editor, and live app preview. Installs from Anthropic's apt repository, so updates arrive through regular package updates.

49Claude FM is on the air. `/radio` opens the lo-fi radio stream in your browser for something to code to, and prints the stream URL when no browser is available. Not available on Amazon Bedrock, Google Cloud's Agent Platform, or Microsoft Foundry.
