ดาวน์โหลด Claude Code 2.1.172

- Sub-agents can now spawn their own sub-agents (up to 5 levels deep)
- Amazon Bedrock now reads the AWS region from ~/.aws config files when AWS_REGION isn't set, matching AWS SDK precedence; /status shows where the region came from
- Added a search bar when browsing a marketplace's plugins in /plugin
- Added model attribute to the claude_code.lines_of_code.count OTEL metric
- Fixed sessions using 1M context without usage credits getting permanently stuck — the session now automatically compacts back under the standard context limit
- Fixed a repeating "an image in the conversation could not be processed and was removed" error when the conversation contained multiple images
- Fixed the agents view keeping a session under Working with a busy spinner for up to 30 seconds after the worker replied
- Fixed background agents potentially reading another directory's project settings (.mcp.json approvals, trust) when dispatched onto a pre-warmed worker
- Fixed background-session attach failing with EAUTH for sessions started on an older version after the daemon auto-updated
- Fixed a background sub-agent staying stuck as "active" in the agent panel after a nested agent it spawned was stopped
- Fixed /model suggestions in the claude agents dispatch input rendering with a misleading slash prefix and showing models disabled for your org
- Fixed availableModels restrictions not being applied to subagent model overrides, the agent dispatch model picker, and the advisor model
- Fixed availableModels allowlists hiding the /model picker's Opus and Sonnet 1M rows when entries use version-specific IDs like claude-opus-4-8
- Fixed the /model picker on Bedrock offering models the provider doesn't serve — selecting one silently switched the session model and lit the selection marker on multiple rows
- Fixed model IDs getting a doubled 1M-context suffix (e.g. [1M][1m]) when ANTHROPIC_DEFAULT_OPUS_MODEL already includes one
- Fixed opusplan model setting not shipping with 1M context in plan mode for entitled users; the opusplan[1m] workaround now also correctly switches to Opus in plan mode
- Fixed WebFetch(domain:*.example.com) wildcard domain rules never matching subdomains in allow, deny, and ask position, and file permission rules with mid-pattern wildcards (e.g. Read(secrets-*/config.json)) being rejected at startup
- Fixed up-arrow prompt history showing the main agent's prompts while a subagent's chat tab is open
- Fixed memory recall not finding mounted team memory stores (CLAUDE_MEMORY_STORES) in remote sessions
- Fixed workflow validation rejecting scripts whose prompt strings or comments merely mention Date.now()/Math.random()
- Disable mouse tracking on Windows consoles that don't fully support it
- Fixed the /plugin marketplace list losing its cursor after backing out of a long plugin list, and Esc from the plugin browser returning to the wrong tab
- Improved performance in long conversations by removing redundant message normalization and avoiding full message-history transforms when streaming tool-use state is unchanged
- Reduced idle CPU usage: /goal status chip no longer re-renders the terminal at 5 Hz while idle, and fewer UI re-renders while subagents run in parallel
- Improved Claude in Chrome tool loading: browser tools now load in a single batched call instead of one per tool
- Improved the non-interactive Usage Policy refusal message to suggest starting a new session or changing your model
- /code-review now keeps the ultra option visible when you're not signed in to claude.ai, with an explanation that the cloud review requires a claude.ai account
- Shortened the Remote Control footer indicator to "/rc active" and hid it on narrow terminals
- Stopped promoting /loop in remote sessions, where pending loops don't keep the container alive
- [VSCode] Fixed PowerShell tool calls rendering as raw JSON instead of a proper command display and permission dialog, and stripped ANSI escape codes from displayed shell output
