Range Stats: Gun & Ammo Log

v1.6.1 — Hardening release BACKUP & RESTORE - Backups now fully cover the ammunition system: SKUs, purchases, and per-trip consumption are all included. Backups made in 1.5/1.6 still restore and convert automatically. - Retired the legacy ammunition model. A one-time migration converts any old inventory into the unified SKU + purchase system, preserving on-hand counts. The duplicate legacy ammo picker in Add Trip is gone. PERFORMANCE & STABILITY - Exports now run off the main thread for a smoother UI during export. - AI daily-quota tracking is now atomic — no more rare races that could let usage slip over the daily limit. - Internal cleanup: removed dead code and resolved pre-existing lint errors. UI POLISH - The onboarding "Add Your First Firearm" button now properly completes onboarding. - Performance Trends distance filter now works correctly when the unit is meters. - The Firearm Comparison screen now scrolls when content overflows. - Range search is now bounded to the visible map area, and your Default Map Type setting is actually applied. - Eight add/edit forms standardized on a consistent toolbar Cancel/Save layout. BUG FIXES - Deleting a firearm now also removes its leftover ammo-consumption records. - Add Trip no longer silently discards entries missing a firearm — it reports the problem. - Adding an ammo purchase now blocks a negative cost. - Exported files are timestamped more precisely to avoid name collisions during rapid exports. - Testing your AI coaching API key now correctly distinguishes an invalid key from a temporary network problem.
