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 and ship together.
6× the battery life, 96,000 free books, and a much better reader
Reading on one charge went from about 15 hours to about 90. A free library of 95,938 books arrived in both apps. Sending books to your device finally works the way it should.
Notes for 0.6 and earlier are on the firmware releases page. We are writing them up properly here in time.
