## What's new in 0.5.0 Alpha 3

Library and stems now saved to ~/Documents/StemDeck

Your entire library ÔÇö metadata, folders, mix state, stem preferences, and extracted audio files ÔÇö now lives in ~/Documents/StemDeck/. This makes it visible in Finder, eligible for iCloud Drive backup, and means it survives any app reinstall or upgrade without any action on your part.

Previous versions stored everything inside ~/Library/Application Support/ which is hidden from Finder and wiped on reinstall.

WebKit stale-data eliminated automatically on macOS

Every upgrade used to leave stale cached state in ~/Library/WebKit/app.stemdeck.desktop, causing inconsistent behavior that required manually deleting three system folders. That folder is now cleared automatically on version change ÔÇö no user action needed, ever.

A two-phase bootstrap ensures no data is lost during the transition: the first launch after upgrading migrates your existing library into the new location, then marks it safe. Subsequent upgrades clear WebKit freely.

Ubuntu 26.04 / Python 3.14 compatibility

Ubuntu 26.04 ships Python 3.14 by default, but PyTorch 2.6.0 doesn't have wheels for it yet. run.sh now explicitly targets Python 3.12, and pyproject.toml enforces <3.14 so the installer never selects an incompatible interpreter.

Docker: pip timeout extended for slow connections

The Docker build was timing out mid-download of the 766 MB torch wheel on slower connections. pip install now runs with --timeout 300 to handle this gracefully.

Installing

Drop the new .app into your Applications folder and launch. Your library will be migrated automatically on first launch ÔÇö no manual steps required.

Artifact build
