Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

# Claude Code v1.0.1 Changelog

Related

Other releases about the same thing. Found by shared names or similar wording; neither means one caused the other.

Enhanced Model Support Detection#

  • Added new function vd9 for intelligent model availability checking based on deployment environment
  • The function determines which Claude models are available based on the current environment:
  • Bedrock deployments: No models available through this check
  • First-party deployments: Access to Claude 3.7, Claude Opus 4, and Claude Sonnet 4
  • Other deployments: Access to Claude Opus 4 and Claude Sonnet 4 only

This feature allows the CLI to dynamically adjust available model options based on the deployment context, ensuring users only see models they can actually access.

Import Reorganization#

  • Streamlined Node.js imports for better module organization:
  • Consolidated process import: Now uses import { cwd as hB0 } from "node:process" instead of a default import
  • Consolidated stream import: Now uses import { PassThrough as N35 } from "stream" with named import pattern
  • Removed redundant import statements while maintaining all functionality

Anthropic’s official release notes

Published verbatim by Anthropic for v1.0.1. Text is unmodified from the upstream changelog. Everything else on this page came out of the bundle instead, which is why the two lists don't match.

  • Added DISABLE_INTERLEAVED_THINKING to give users the option to opt out of interleaved thinking.
  • Improved model references to show provider-specific names (Sonnet 3.7 for Bedrock, Sonnet 4 for Console)
  • Updated documentation links and OAuth process descriptions
System prompt
