The latest version of the Play Store is no longer 3.7.11 - say hello to v3.7.13. I haven't found anything different from 3.7.11 just yet - it likely only contains bug fixes. There's no reason to lag behind, however, so if you're running a Play Store with a version lower than 3.7.13, jump right to the download mirrors below. Before you do that, let me point out a few things.
Upon playing with the Store further, I did discover a new feature compared to v3.5.19 that I didn't mention last time - inline app links in search suggestions. Take a look at searching in 3.5.19 (on the left) and 3.7.13 (on the right) - direct app links are now mixed in with suggested spellings. A subtle change, but if I can save a few clicks here and there and get to results faster, why not?
And a few earlier ones:
If you missed the 3.7.11 post, I'll mention this feature again as well - you can now set your preferred sharing method (long-press on the new field to the right of the share dropdown). I set mine to Gmail so that I can quickly share new apps with the team. Neat.
