Release notes.
What changed in each version, in plain words, with the numbers we measured. Flowe is one release train: the firmware and both apps carry the same version with platform availability shown in each release note.
6× the battery life, 90,000+ free books, and much faster book transfers
Reading on one charge went from about 15 hours to about 90. A free library of 90,000+ books arrived in both apps. Now with faster book transfers, resumable uploads, and better priority controls. Plus Memory Nap, voice and typed commands, and new ways to find your next book.
Notes for 0.6 and earlier are on the firmware releases page. We are writing them up properly here in time.
