The latest update to iDraw most notably adds support for a couple of iOS 8 features, namely, iCloud Drive and Handoff.
As a result, you can now save and access iDraw files on iCloud Drive and use Handoff to seamlessly work on an iDraw file on another iPad or on iDraw for Mac, which itself has been updated with support for the same features on OS X Yosemite along with other enhancements.
The update also introduces a new blur effect feature and improvements to the apps annotation extension, thereby letting you:
Apply blur effects to shapes and images
Enable, disable, and adjust blurs from the Effects pane
Adjust the blur radius to control the appearance of the blur effect
Add arrows, notes, and shapes to photos
Share annotated photos via Email, Facebook, and Twitter
Print annotated images, save to Photos, or copy to the pasteboard
Furthermore, the new version of iDraw for iPad includes enhancements to importing and exporting along with various minor improvements and bug fixes.
