What's New

Remember the old days when we used to have just 192 problems offline? Although we had fewer problems, we were totally free from network!

Now the freedom is back! Per your request I've added an offline mode switch to download all problems and solutions locally, you won't need network anymore!

For my dear users who are still using version 1.1.5, it's time to upgrade!

This is a pretty complex change. If you find anything wrong, please don't hesitate to email me about it.

5 stars if you like it!
