On Wednesday, 9th July, you should expect the update to 1.30. It will implement a big change in the friend invite process. Now you will be able to get more rewards on it, track progress of your friends and invite them in many ways: via e-mail, Facebook, Google+ and Twitter.
Also some other changes will be introduced, e.g. speed of default battle will be increased to level 2 or you will not get any battle points for defeating just one army. Finally, there will be many bugfixes. We hope you like this news!
