## Release Schedule
The project follows a structured release process for each minor version, consisting of three distinct phases:
1. **Development Phase** - 1 week
- Active development of new features
- Code changes merged to the development branch
2. **Feature Freeze** - 1 week
- No new features accepted
- Only bug fixes are cherry-picked to the release branch
- Testing and stabilization of the codebase
3. **Publication**
- Release is published at the end of the freeze period
- Version is finalized and made available to all users
### Nightly Releases
Nightly releases are published daily at [https://github.com/Comfy-Org/ComfyUI_frontend/releases](https://github.com/Comfy-Org/ComfyUI_frontend/releases).
To use the latest nightly release, add the following command line argument to your ComfyUI launch script:
```bat
--front-end-version Comfy-Org/ComfyUI_frontend@latest
```
## Overlapping Release Cycles
The development of successive minor versions overlaps. For example, while version 1.1 is in feature freeze, development for version 1.2 begins simultaneously.
### Example Release Cycle
| Week | Date Range | Version 1.1 | Version 1.2 | Version 1.3 | Patch Releases |
