The three pillars of iWork (Pages, Keynote and Numbers) may not be as popular as their Microsoft counterparts (Word, PowerPoint and Excel), but on Tuesday evening, Apple made it easier for fans of either software bundle to work interchangeably on either platform.

Apple released updates for its entire iWork line on Tuesday, including significant updates to Pages, Numbers and Keynotes. Most iOS users will notice many changes to the platform, while Mac users will notice subtle tweaks and additions to make the Mac experience resemble the changes in iOS.

Here's what Apple has to say about each of its newly-updated products:

For Mac users, iWork update 9.3 will add support for iWork for iOS 1.7 apps, and comes recommended for all users of iWork 9.0 and later.
Apple offers detailed information for these Mac and iOS updates, as well as the changes for each specific application, on this site: http://support.apple.com/kb/HT5534.
For iWork users on either Mac or iOS, the updates will be found in either platform's respective App Store. For Mac users that purchased iWork in a box, the update will come in the form of a Software Update.
Each separate iWork application costs $19.99 via the Mac App Store, but physical bundles of all three products can be found online for around $30. On iOS, Pages, Keynote and Numbers all cost $9.99 to download.
