Just a few days after the release of version 1.7 of the iWork apps for iOS, Apple has released version 1.7.1, a bug fix update. The update notes for Pages, Numbers, and Keynote all say simply that version 1.7.1, "resolves issues related to Accessibility settings."
Pages, Numbers, Keynote
If you look on iTunes, you'll see more detailed notes for each app, but though labeled as "What's New in Version 1.7.1," the bullet points are really the patch notes for version 1.7. As noted above, the only stated difference in the update is the Accessibility bug fix.
All of the updates are free and are available now on the App Store at the links above. These are hybrid apps for both iPhone and iPad.
