Apple released iWork 9.0.5 last week that offers, among other changes, enhancements to the iWork.com beta service, including the ability to play Keynote presentations online and new options for public sharing and private online storage.

In an email to iWork.com beta users, Apple had this to say:

“Using Keynote for Mac, share your presentations and let viewers experience them with over 15 animations, video, hyperlinks, and audio. Play back a presentation on iWork.com using the latest version of Safari on a Mac or PC, iPad, iPhone, or iPod touch. Just swipe to advance slides on your iPad using Safari.

”New publishing options for public sharing and private online storage. Upload your documents for private online storage and easily access them from anywhere, or share your documents on social networks using a Public link. Also, you can now embed your presentation seamlessly on a website or blog using the embed code provided by iWork.com .”

Apple launched the iWork.com service in early 2009 and expanded it to work with the iPad in 2010. The service allows you to share your iWork documents online. Using your Apple ID, just click the iWork.com icon in the Keynote, Pages or Numbers toolbar to upload your document and invite others to view it online.

Viewers can provide comments and notes, and download a copy of your document in iWork, Microsoft Office or PDF formats. A consolidated online list of all your shared documents indicates when your viewers have posted comments.
