What's New in Classic Mini Toolbox
2.11.0
July 22, 2026
Fixes for Sustaining Members: • If you support us through Patreon, the website, or a complimentary membership, the app now correctly recognizes you everywhere — maintenance tracking, your garage, and service history unlock on sign-in instead of showing a subscribe prompt. • Restore Purchases now also checks your membership on our servers, not just the App Store. • Members are no longer shown the Discord invite on every launch — just once when your membership starts. • Fixed sign-in and sync errors affecting some longtime users after our backend migration. Also in this release: • Updated and refined for iOS 27. • The Maintenance control now appears correctly in Control Center. Thanks for supporting Classic Mini DIY!
