Version 2.13.0 brings 10 customer-facing changes to ARC Library. Role or platform labels appear only where a change is specific to that experience.
New
Precise Progress Tracking
Track your reading with exact numbers instead of an imprecise slider. Type the exact page, audio time (hours + minutes), or percentage — and it auto-saves on the spot.
Overview Tab (Desktop)
A brand-new first tab on desktop gives you an at-a-glance summary: progress tracking, reading pace, key dates, and quick PR task management — all in a two-column layout.
Smarter Reading Pace
The reading pace section now shows your actual pace vs. required pace side by side, with an on-track indicator. Calculated from your real progress history, not just deadlines.
Timezone & Notification Settings
Set your timezone and preferred notification time directly in settings. Notifications automatically reschedule when you change your preferences.
Grid Column Preferences
Customize how many columns your library grid displays on mobile and desktop independently. Your preference syncs across all devices.
Improved
Cumulative Progress Chart
The reading pace chart now shows cumulative progress over time instead of daily rate, giving a clearer picture of your reading journey.
Faster App Performance
Optimized component rendering with memoization and reduced unnecessary re-renders across the app for a noticeably snappier experience.
Better Background Sync
When you switch back to ARC Library after using other apps, your session and data now refresh more reliably.
Fixed
Profile Data Reliability
Fixed an issue where social links, reading tastes, and sort preferences could fail to load. Profile data is now fetched in a safer way that prevents one missing field from breaking everything.
Data Loading Stability
Resolved issues with entity data merging, moderator access, and admin panel queries for a more stable overall experience.
