There are five new puzzle sizes: 352, 396, 432, 480, and 500 (for iPads). On the other hand, phones are now limited to a maximum size of 192.
You can search Pixabay, Pexels, and Unsplash from within the app.
Photos imported via this searching capability have accurate authorship information and there are hyperlinks to the photographer's profile page and other information on the providing site.
"Site search" capability must be explicitly enabled with a periodic login but a single login covers all three sites.
The help system and the associated tips has been substantially revised to favor smaller quantities of help, often delivered as "context help" (use a long press on a feature of the screen).
The main help menu and the Help options still exist but they, too, use the new system.
Help is displayed in a movable box that persists on the screen while you interact but can be dismissed at any time.
There has been a substantial revision of the background color dialog, permitting tinting as well as grayscale.
The "Title and Notes" capability of version 1.2 has been expanded, in 1.3, to a broad set of properties for puzzles and images.
In part, these exist to help ensure that photographers who contribute to Unsplash, Pexels, and Pixabay get credit when you use their photographs as puzzles.
There are also other properties which you might find useful.
The top control in the main view is changed to be easier to read and interact with.
You can now directly search your Photos from within the app. No need to open the Photos app directly.
The notes editor supports markdown.
You can initiate a re-crop or re-cut of a puzzle's image directly from the puzzle thumbnail
When piece rotation is enabled, pieces can be rotated in a tray view as well as in the solving pane.
There is a new global option to prefer images to be shown initially in the main view rather than always starting with puzzles showing.
When there is a failure to import a shared puzzle because it is too large, the app no longer crashes; rather, the failure causes an error popup, similar to what happens when you import from a corrupted file.
Since older releases did not have this feature, a too-large exported puzzle can still cause a 1.2 version of the app to crash, so you are warned when exporting large puzzles.
After a crash (usually) the next restart of the app gives you an opportunity to send a crash report.
From the main help menu you can log short comments. If you subsequently send feedback that includes the logs, these comments will show up in sequence with whatever else was going on.
Some effort has been given to making the experience better on phones.
For example, there is a new layout for landscape mode on phones, providing more space top to bottom.
However, an iPad, if you have one, is still recommended.
When deleting the last object in a category (images, puzzles, started) another non-empty category is shown. Empty categories are not offered.
You can (re)install supplied samples at any time (useful when a version update comes with new samples, which would normally only be installed in a from-scratch situation).
