> Claude Code v0.2.85, released 25 Apr 2025 (2025-04-25). 4 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

Web version: https://changelogs.core-directive.com/v/0.2.85

## Changes

### New Features

Environment Variable Management

- **Enhanced environment variable handling**: Environment variables are now loaded from multiple sources in a hierarchical manner. The new system merges environment variables from:
- Local settings (`localSettings`)
- Project settings (`projectSettings`)
- Managed settings (`managedSettings`)

This allows for more flexible configuration management across different scopes.

Model Support

- **Added support for Claude 3.5 Sonnet v2 (October 2022 release)**:
- First-party API: `claude-3-5-sonnet-20241022`
- AWS Bedrock: `anthropic.claude-3-5-sonnet-20241022-v2:0`
- Google Vertex: `claude-3-5-sonnet-v2@20241022`

The new model includes updated pricing:

- Input tokens: $3 per million
- Output tokens: $15 per million
- Prompt cache write: $3.75 per million
- Prompt cache read: $0.30 per million

Cost Tracking

- **Improved unknown model cost handling**: When using models without known pricing information, the system now properly flags this with `hasUnknownModelCost = true` to alert users that cost calculations may be incomplete.

### Improvements

Settings Management

- **New settings hierarchy**: Settings can now be stored at different levels with clear visual indicators:
- Local project settings: `On this machine in [path]`
- Project settings: `Checked in at .claude/settings.json`

- **Settings persistence**: New functions for reading and writing settings with proper JSON formatting and indentation.

Performance

- **Lazy initialization**: Added lazy loading for certain operations using a new `jx1` function that initializes components only when needed.

Developer Experience

- **Better cost display**: The cost summary now handles cases where cost calculation might be unavailable, providing clearer feedback to users.

### Technical Changes

- Bumped version from 0.37.0 to 0.40.0
- Refactored stream imports to use named imports (`PassThrough`) instead of default imports
- Improved process imports to use named imports (`cwd`) for better tree-shaking
- Added schema validation for package information using Zod
- Removed git checkout special case handling from permission checks

### Bug Fixes

- Fixed environment variable loading to properly merge variables from all configuration sources
- Improved error handling for model configuration fetching with proper fallback behavior
