We have reported Weixin’s ambition on international market, so not a big surprise, we see
1. Weixin officially has an English name, WeChat;
2. Weixin now supports 7 language including Thai, Vietnamese, Indonesia, Portuguese, Traditional Chinese and English;
4. International users can now login WeChat with its Facebook account.
Feature-wise, WeChat added one called Circle, which allows users to share photos with a group of friends. I would say Circle is just like Path, but with a bad UI.
If you have it downloaded, my id is: ganglu.
