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):

The new model includes updated pricing:
- Input tokens: $3 per million
- Output tokens: $15 per million

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