Version 6.7.2

Release Date: 2016.11.23

##Framework changes:

• The framework targets iOS 8+. Note that the tools still require iOS 9+ due to using APIs only available in iOS 9+, but that old versions of the tools may be used with the new version of the framework after updating PDFNet APIs.

##Bug fixes:

• In the tools, the popup for sticky notes now points to the correct location.
• Fixes a potential crash when optaining a PTPoint from a PTQuadPoint, and disposing of the PTQuadPoint before the PTPoint.
