Along with a totally new device (the iPad Pro) coming out today, Apple today released updates to all of the iWork apps both on iOS and Mac OS X.
The updates primarily do two things: provide bug fixes for compatibility with Microsoft Office documents and make the apps more stable on both platforms.
The Mac update fixed an issue in Keynote when exporting presentations as images, and another with master slides that included links. Pages on the Mac can now open some Microsoft Word documents that were previously impossible to open, and resolves an issue that prevented the use of Look Up for words in lists. Numbers can now open more Microsoft Excel spreadsheets.
On the iOS side, Apple fixed Keynote for an issue when opening presentations that contained many images, and Numbers got a fix for a problem where documents wouldn't open to the last saved position.
If you're not a current user of Apple's productivity suite -- which is available on Mac OS X, iOS and on the web -- you can download the apps below. The updates are free, and the apps are $19.99 each for the Mac, and $9.99 each for iOS.
