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.

A big update: a real page-curl animation for turning pages, a full dark theme (Day, Night, or follow System), and Left-Handed Page Turns for one-handed reading — all new in Settings. Series information now comes through from Kavita libraries, with a proper Series sort. Standard Ebooks connects with your Patrons Circle email. Plus a wide pass of reliability fixes: more accurate cross-device and Kavita progress sync, large self-hosted libraries no longer silently losing books from search, and a range of smaller fixes across search, downloads, and the reader.
