v5.0

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

v4.0

• One-shot create, format, and mount pipeline for streamlined disk setup
• Image manager with batch select-to-delete and clear unmounted
• Auto-mount saved images at boot without opening the app
• Visual refresh: rotating backgrounds, animated cards, modernized sheets
• Auto-increment disk names with creation timestamps
• Module banner and action script for root manager integration
• Batch image operations and improved image lifecycle management
• Bypass FUSE for configfs lun writes on Android 11+ (direct sysfs path)
• Merged SELinux policy into sepolicy.rule for Magisk compatibility
• Hardened bootloop guard with retry loops and resource leak fixes
• Socket read timeout and connection reliability for daemon client
• Fixed device removal index mismatch and coroutine lifecycle
• Escaped single quotes in automount config paths
• CI pipeline with auto-build, signing, and release publishing

v3.1

• Full app and installer localization with 32 languages
• Auto-detect device locale during module installation
• Accent color picker (system default, almost black, white)
• In-app usage guide accessible from menu
• Material 3 companion app with pull-to-refresh and bottom sheets
• SELinux enforcing with dedicated msd_daemon domain
• Boot guard with exponential backoff daemon respawn
• Multi-ABI support (arm64, armv7, x86_64)
• Create virtual disk images from the app
• Mount up to 8 USB devices simultaneously
