Evernote released a substantial Skitch 2.5 update for both OS X and iOS today, which makes the four-month wait since the last Mac update seem worthwhile. The new features are primarily geared toward adding feedback and notes to PDFs, and Evernote Premium members get two of the best ones: PDF Annotation and Skitch Summary. As the name suggests, the former lets you mark up PDFs with text, arrows, shapes and highlighter tools, while the latter collates all the added notes into a single "summary" so users can get a visual overview of what's changed.

Other non-premium updates include a new Stamps tool that'll let you mark a document with symbols to indicate approval, disapproval, a question mark, an exclamation point and (of course) a heart. You can also add notes to those symbols to flesh your opinion out a little more. What about filling out those pesky PDF forms? Skitch is bundling a plain text notation mode just for that, too. Last but not least, there's a handy Tool Tip to guide users through all the new features. Those on the Apple side of things can download the new Skitch straightaway, but as there's no word on when Windows and Android users will get the update, they'll have to content themselves with staring at the screenshots above and below for now.
