We released Penultimate 6.2.2 to the App Store earlier today.
This version addresses some persistent crashes users were seeing with iOS 11.
You can download the Penultimate app from the App Store.
So what is the best way to report bugs in the new version? As there is an issue with the Apple Pencil and the iPad Pro 10" where the writing is off by an inch, meaning it does not appear right under the pencil.
