  • Added support for Google Play Store 3.5.15. Please note that Play Store is capricious with Market links because it relies more on Google’s servers than before. If you want more control we encourage you to ask Google. Remember: it’s their app. Let them know the legitimate goal you want to achieve (eg: simply detach an app that you purchased on a different app store) and ask them how the heck you’re supposed to do it. Once they provide a solution, we’ll strive to give you full control of it!
  • Improved the app backup code (and the rest of the app) to fully support APK files that have non-standard names.
  • [PRO] Added new “Disable Market app Auto Updater” feature.
  • Fixed a possible FC when using Market Update Helper.
  • Speed optimization and minor GUI tweaks.
  • Updated translations.
