NepTools v2.9.0

NepTools v2.9.0 (versionCode 49) - Release Notes

This release resolves core issues in calendar event notifications, background alarm restoration across reboots, data restore cache invalidation, numeral preference persistence, and widget synchronization.

Fixed

• Calendar Event Notification Fidelity & Collision: Fixed an issue where calendar event reminder notifications showed a generic fallback label instead of the user's event title and note, and caused multiple event notifications to overwrite each other. Notifications now surface title, note, specific day deep-link, and unique IDs.
• Reboot & Timezone Alarm Loss: Restored the persistence of user calendar event alarms across device reboots, time changes, and app updates by adding rescheduleAll to UserEventManager wired into BootCompletedReceiver and application cold start.
• Data Restore Cache Stale State: Fixed an issue where restoring habits from a backup file wrote directly to disk without purging the in-memory logsByDateCache in HabitRepository, causing stale heatmap and streak data to persist. Also added automatic alarm rescheduling for restored calendar events.
• Nepali Digits Preference Cold-Start Persistence: Fixed a regression in ThemePrefs.load where the stored "np_digits" boolean was ignored and overwritten on every app launch, ensuring the user's numeral format choice is retained.
• Midnight Monthly Calendar Widget Rollover: Added NepToolsMonthWidgetProvider.updateAllWidgets to the midnight notification rollover routine, ensuring homescreen month calendar widgets accurately update the highlighted today cell at midnight.

NepTools v2.8.9

NepTools v2.8.9 (versionCode 48) - Release Notes

This release restores full navigation access across all tools, refines daily horoscope display, fixes memory cache invalidation on habit deletion, and aligns notification preference keys.

Fixed

• Tools Navigation Gate Failure: Fixed an issue where tapping any utility from the Tools screen or Home screen silently dropped navigation because of an overly restrictive internal allowlist. All 50+ tool routes and dynamic date screens are now fully accessible.
• Habit Log Cache Invalidation: Deleting a habit previously deleted its persistent logs in storage but failed to clear the in-memory date index, causing deleted logs to linger until process termination. Cache invalidation is now properly invoked upon deletion.
• Subscription Notification Setting Sync: Resolved an inconsistency where turning subscription notifications on/off in Settings saved to notif_sub but startup preferences read notif_subs, causing user toggles to be ignored after app restart.
• Ekadashi Year Switch State: Keyed events state to selectedYear so switching years immediately resets the active cache and displays the proper loading state.

Changed

• Daily Horoscope Interface: Removed the redundant top-bar refresh button and associated random seed override; daily readings now deterministically generate based on the user's selected rashi and current date.

NepTools v2.8.8

NepTools v2.8.8 (versionCode 47) - Release Notes

A correctness, performance, release-safety and accessibility pass. No new tools; this release makes
existing features correct and usable on real devices.

Fixed

• Habit streak counter (important): The current-streak figure was being reset to 0 every morning
  before you logged the day, and stayed at 0 on any scheduled rest day. A run of completed days was
  discarded on screen. Streaks now carry over from yesterday, a day you have not logged yet no longer
  breaks the chain, and a scheduled rest day is treated as neutral rather than a miss.
• Ekadashi and sacred tithi list: Opening the screen, or changing year, froze the UI for several
  seconds while a full year of panchang calculations ran on the main thread. Calculation now happens
  in the background with a loading indicator, and each year is solved only once.
• Habit heatmap and statistics: The 52-week grid became progressively slower the more history you
  accumulated, because the full check-in log was re-parsed for every day on every refresh. The log is
  now indexed once and reused.
• Background battery drain: Leaving the sound level meter or the spy camera detector with the
  screen off no longer keeps a high-frequency sensor loop alive.
• Cold start colour flash: The window background followed the system dark setting while the app
  followed its own setting, producing a one-frame colour jump. Both now resolve from the same choice.
• Default language: A first run on an English phone opened in Nepali. The app now follows the
  device language until you choose otherwise.
• Any app could crash NepTools: The exported main activity accepted an unvalidated navigation
  route from any installed app. External routes are now validated against an allowlist.

Improved

• System dark mode: The app ignored the Android dark theme setting. Appearance is now a
  System / Light / Dark choice in Settings, defaulting to System.
• Keyboard handling: The on-screen keyboard covered the bottom of every form, hiding the field
  being typed into and the submit button.
• Readability: Secondary text contrast was below the WCAG AA minimum in light mode, which was
  hardest to read outdoors. Improved across the palette.
• Confirmation before deleting: Deleting a habit or subscription now asks first, since both
  permanently discard history.
• Boot performance: Restoring the daily date notification after a reboot no longer runs on the
  main thread.
• Build reliability: Gradle heap raised and compiler strategy corrected; emulator-only native code
  no longer ships in release builds.

Security

• Release signing is now enforced: If the release keystore is missing, the release build fails
  instead of quietly producing an APK signed with the publicly known Android debug key. Previously a
  missing keystore still produced a working, distributable build that anyone could impersonate.
• Obsolete APK v1 signing disabled.
• Removed a permission the app never used, and removed three debug-only broadcast handlers that any
  app on the device could have triggered.

Verification

• 50/50 unit tests pass, including 6 new regression tests for streak arithmetic.

• Debug build compiles with no errors; release-signing guard verified to fail closed.

• Manual on-device testing is still recommended, particularly for the habit streak values and the
  new appearance control.

• ABIs: arm64-v8a, armeabi-v7a (emulator-only x86_64 no longer shipped)

• Updater: publish app-release.apk.sha256 alongside the APK. The in-app updater
  refuses to auto-install when no checksum resolves, so this asset is required.
