Breaking Changes

  • Storage relocated from /data/misc/usbmassstorage/ to /data/adb/Usbmanagement/ (auto-migrated on first boot)
  • memfd RAM copy architecture removed — images mount directly from disk with zero memory overhead

New Features

  • Device reboot button in the main toolbar with confirmation dialog
  • Path-based mount protocol for file:// URIs — daemon opens images directly via /proc/pid/fd/N
  • Images of any size now mount instantly regardless of available RAM
  • Import external disk images into managed storage from any file picker
  • Batch stat/blkid queries for image metadata (single shell call instead of 2N)

Performance

  • R8 full mode enabled — release APK shrunk ~70% via aggressive tree-shaking and class merging
  • Log.d/Log.v calls stripped from release builds via ProGuard rules
  • Baseline profile added for Compose runtime AOT compilation on first install
  • Compose stability configuration for deterministic recomposition skipping
  • All infinite animations migrated to graphicsLayer — draw-phase only, zero recomposition overhead
  • Shell.cmd() calls removed from main thread: composition body, onClick handlers, and store operations
  • File I/O in DeviceCard moved to background coroutine with LaunchedEffect
  • SharedPreferences reads wrapped in remember to prevent redundant disk access during recomposition
  • enrichWithSize and scanImages batch all shell calls into single scripts
  • Regex instances hoisted to top-level compiled vals across 5 files
  • Keyed LazyColumn items for stable item identity during list mutations
  • @Stable annotation on UiState for correct recomposition skipping
  • configChanges declared on MainActivity to prevent unnecessary Activity recreation

Bug Fixes

  • Fixed mixed mount protocol where sequential daemon calls cleared previously mounted devices
  • Fixed enrichWithSize running java.io.File().length() as unprivileged app context — now uses root shell
  • Fixed automount config corruption from unchained shell writes (newline vs && join)
  • Fixed restartDaemon not killing parent service.sh loop alongside daemon process
  • DAC traversal fix: /data/adb/ mode 700 blocked daemon — added chmod o+x in service.sh
  • Tightened system_data_file SELinux permissions — removed stale write/create from old storage path
  • Added adb_data_file rules to runtime SELinux patcher for storage migration
  • Added untrusted_app fd use and shell_data_file read to KSU rules

Module

  • Full storage migration with backward-compatible path detection on first boot
  • Old /data/misc/usbmassstorage/ directory removed after successful migration
  • Gadget backup, automount config, and boot counter relocated to /data/adb/Usbmanagement/
  • Expanded SELinux policy for kernel→adb_data_file read access
  • Uninstall script updated for new data directory cleanup
