## Jan v0.7.0: Jan Projects
Jan v0.7.0 is live! This release focuses on helping you organize your workspace and better understand how models run.
### What’s new
- **Projects**: Group related chats under one project for a cleaner workflow.
- **Rename models**: Give your models custom names for easier identification.
- **Model context stats**: See context usage when a model runs.
- **Auto-loaded cloud models**: Cloud model names now appear automatically.
---
Update your Jan or [download the latest version](https://jan.ai/).
For the complete list of changes, see the [GitHub release notes](https://github.com/janhq/jan/releases/tag/v0.7.0).
