We're almost two weeks into the Play Store, and the new version isn't available for download from the Play Store. It might be worth considering downloading the APK directly from the MyRoute website. Version 5.2 hasn't had any major issues (we used it for a 10-day tour of Italy, Slovenia, and Austria) without any issues. However, if the new version brings major fixes, it'd be a good idea to make it available as soon as possible.
