Claude Code is an agentic coding tool that lives in your terminal, understands your codebase, and helps you code faster by executing routine tasks, explaining complex code, and handling git workflows - all through natural language commands.

Claude Code v2.1.196 adds org-default models, clickable file attachments, and an always-on stream watchdog.

$ git clone --branch v2.1.196 https://github.com/anthropics/claude-code.git
# already have the repo? check out this version:
$ git checkout v2.1.196

$ CLAUDE_ENABLE_STREAM_WATCHDOG=0 claude

• ›Adds organization default models: admins set a model in the org console; users see 'Org default' or 'Role default' in /model when no personal selection is made.
• ›Adds readable default session names at start, making sessions easier to identify and resume.
• ›Adds clickable file attachments in chat — Cmd/Ctrl-click reveals the file in Finder/Explorer.
• ›Enables the streaming idle watchdog by default for all providers: aborts and retries any response stream that produces no events for 5 minutes; disable with CLAUDE_ENABLE_STREAM_WATCHDOG=0.
• ›Improves background agents: workers killed by a daemon restart are automatically resumed from where they left off when the agents view next opens.

Autonomous coding agent as an SDK, IDE extension, or CLI assistant.

• ›Adds TypeAdapter support for EvaluatorContext, enabling structured validation and serialization of evaluator context objects.
• ›Adds Anthropic _20260209 web tools with server-tool replay support for the Anthropic provider.
• ›Serializes instrumentation message attributes using to_json instead of json.dumps for more robust OpenTelemetry attribute handling.

llama.cpp b9840 adds DeepSeek V4 model support including conversion, multi-sequence inference, and Flash Attention.

$ git clone --branch b9840 https://github.com/ggml-org/llama.cpp.git
# already have the repo? check out this version:
