1.3.0
July 16, 2026
Mark Your Books with Color-Coded Highlights Select any passage in EPUB or PDF, choose a color, and it highlights persistently while reading. Every highlight auto-saves to Settings → Text Highlights and syncs via iCloud to all your devices. Tap a highlight to change its color or delete it. Browse all highlights for a book directly in the reader's Bookmarks sheet. Improved Definition Lookup No more automatic pop-ups when you select text. Now you control what happens: tap Define for the definition, Highlight to mark it, Copy to save it, or Search the library — all in one convenient menu bar. Your Series, Organized Automatically If your Kavita or Calibre server has series metadata, Sutra groups your books by series in the Collections shelf — so you can browse and pick up the next book without losing your place in a sequence.
