Apple updated Pages on Wednesday with the ability to publish your books directly to Apple Books (the renamed iBooks). The move could (likely) means that iBooks Author is a dead-app walking, though it does include ebook design features not yet found in Pages.
The ability to publish directly to Apple Books is included in Pages 7.3 for Mac and Pages 4.3 for iOS.
Patch Notes for Pages 7.3 for Mac and Pages 4.3 for iOS
