Update:
Thanks errornokia for the tip. Not only, WeChat, when we checked many apps including Facebook, Instagram, Facebook messenger and more have Windows Phone 8.1 appearing now in “Works with” section. Is the release closer than we thought?
Windows Phone 8 apps are supposed to be compatible with Windows Phone 8.1 devices according to leaks, while Windows Phone 8.1 apps will be compatible with Windows Phone 8 devices only when they run Windows Phone 8.1 update.

Thanks Ofentse Letsholo for mentioning it.
