Thor v1.90.1 Release Notes

A focused stability & smoothness release on top of v1.90.0 — hardened APK installation, a fix for the Settings crash on large fonts, and a broad pass to eliminate memory leaks and UI jank across the app.

What's Changed

📦 Installer

• No more false "downgrade" blocks: normal apps that bundle helper .apk assets (e.g. Muntashirakon App Manager, MT File Manager) were being misidentified as a system downgrade and blocked. A file is now recognized as a single APK by its top-level manifest instead of by any nested .apk entry, so it installs correctly. (#207)
• .xapk installs fixed: bundles that failed with "Error: failed to parse package" now install — tolerant manifest parsing (numeric version_code, missing fields) and correct base-APK selection that skips config splits. (#159)

🐛 Crash Fix

• Settings no longer crashes with system Font Size = Maximum and Display Size = Larger. The connected button group was rebuilt (via Asgard 1.0.1) so it can no longer produce the internal ButtonGroup measurement crash at any font/display scale. (#197)

🚀 Performance & Smoothness

• App-list pull-to-refresh no longer stacks background collectors — previously each refresh leaked broadcast receivers and re-ran a full package enumeration.
• Privilege availability checks (Shizuku/Dhizuku binder IPC) are now suspend and main-safe, moved off the main thread across Settings, App Details, App List, and the installer — noticeably less jank.
• Less recomposition work: list filtering/sorting and date formatting are memoized in App Details, Freezer, and Permission Manager.
• App icons decode at their display size — lower memory use and smoother scrolling in the app grid.
• Lifecycle-aware state collection and one-shot side effects throughout (no more background activity launches).

🔒 Stability & Resource Fixes

• Privileged shell/process execution (Shizuku/Dhizuku) now uses bounded waits with guaranteed teardown and daemon reader threads — a hung command can no longer pin a background thread forever or leak file descriptors.
• Fixed a cross-thread data race in the debloat (UAD) cache.
• The biometric prompt no longer orphans a cancellation signal when re-triggered (auto-prompt + manual tap).
• Billing no longer initializes at app shutdown; added a proper teardown hook.
• Removed an unused cache-scanner path that leaked a su subprocess and its file descriptors.

✅ Issues Resolved

• #197 — Settings crash on large font/display size.
• #207 — installation wrongly blocked as a system downgrade.
• #159 — .xapk install failing to parse.
• Also closed #77 (clear cache / force-stop — already fixed) and #161 (tap-to-install — already shipped).
