## Version history (last 5 releases)

### 3.7.25 — 2026-11-04

Book Sources overhaul
• Browse aggregated public catalogs (Project Gutenberg, Wenyuange, The Anarchist Library, Elephant Archives, arXiv, and more) as soon as you open the tab—no need to toggle built-in sources first
• Category filters with a preview row plus an All menu for faster discovery
• Local cache with background refresh so returning feels instant while new results update quietly
• Infinite scroll to load more titles
• Better covers: proxied/cached art when available; clearer generated covers when a source has none
• Custom OPDS catalogs still supported; Audiobooks and Point-Read tabs unchanged
• Sticky header (categories + search) while only the book list scrolls

### 3.7.24 — 2026-10-30

Improved web article import: short links expand automatically, body extraction is more reliable, and login walls are no longer saved as empty books.

### 3.7.23 — 2026-10-28

iPhone Duo / wide layout: Better use of the inner and regular-width screens—dual-page reading, split video layout, landscape tab rail, and clearance for the system vertical bar.
Learn tab: Flip favorited cards; go deeper when unsure (understand → use → communicate). Clearer home preview and motion.
Background resumable downloads: Queue whole books offline, pause, and resume from breakpoints in the background—then auto-import to your shelf.
Corpus notes: Collect reading notes in one place, with export support.

### 3.7.22 — 2026-10-26

Account & AI quota: Sign in with Apple. App Default includes about 100 free AI uses; then buy packs or subscribe. BYOK (your own API key) needs no login and no platform fee.
Subscriptions & IAP: Monthly plan (~1000 AI/month + cloud sync) and AI pack (+1000 stackable). Check status and the paywall in Profile.
Cloud sync: Subscribers sync reading progress, shelf data, favorites, podcast/YouTube subscriptions, and watch history.
Local backup: Export/restore a ZIP from Settings (Files/AirDrop) without signing in—easy device migration.
AI settings: Clearer service setup, connection test, usage tips, BYOK fields, and Free/Premium crown on the avatar.
AI routing: App Default uses the platform pool and quota; your own key still talks to your provider.
Polish & stability: Startup home, settings, and localization updates, plus assorted fixes.

### 3.7.21 — 2026-10-09

1. Fixed display issues on iPad's 'Learn to Use' screen where content was cut off or compressed. 2. Improved speech recognition in 'Use / Communicate' mode for longer, more complete sentences with fewer interruptions. 3. Fixed Mac (iPad version) issue where word lookup during reading wouldn't pause playback or resume properly. 4. Now tap words in saved sentences/phrases to view the full sentence or look up words.
