As part of all of the recent updates, Apple also officially announced new versions of its iWork suite which consists of Pages, Keynotes and Numbers. Each of the apps have received additional UI changes to help them match the new OS X Yosemite aesthetics alongside app-specific functionality improvements. For example, in numbers you can now transpose tablets, Pages adds a new sidebar with comments and other outline views and Keynote now includes new text effects.

These updates will all be released alongside the recently announced release of OS X Yosemite today. Last but not least, Apple will also be releasing matching software updates for the iWork counterparts on iOS all of which will be available for free.
