# Claude Code v1.0.1 Changelog
Changes
2 itemsEnhanced Model Support Detection #
- Added new function
vd9for 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
Internal Improvements
3 items- Code structure: 5,645 function renames for improved code organization
- Bundle size: Minor optimization with net addition of 1 declaration (6,263 total, up from 6,262)
- Structural compatibility: Maintains 100% structural similarity with previous version
Notes
This is a minor release focusing on model availability detection and import optimization. The changes are backward compatible and require no user action.
