# GAIA v0.15.3.1 Release Notes

**Patch release** with Linux installation improvements and minimal profile optimization.

***

## 🎯 Key Changes

### Minimal Profile Optimization

* **Smaller, faster setup**: Minimal profile now uses `Qwen3-0.6B-GGUF` (400 MB) instead of 4B model (2.5 GB)
* **6x smaller download** for quick starts and testing
* Updated all documentation to reflect new size

### Linux Installation Improvements

* **Reliable apt install**: Runs `apt update` before install to prevent 404 errors from stale package cache
* **Cleaner help output**: `gaia init -h` now shows only relevant options (removed global parameters like `--use-claude`, `--model`, `--trace`)
* **Better error UX**: Incomplete model downloads now suggest using `--force-models` flag to redownload from scratch

### Code Quality & Cleanup

* Simplified Linux version check function (34 lines vs 51 lines, -33%)
* Removed unnecessary PATH manipulation on Linux
* Removed debugging code from dpkg installation
* Fixed Pylint errors in lemonade\_installer.py
