Chinese government once blocked the download page of the python website (python.org), when they released python version 2.6.4. It is widely believed that it's because the version number triggered that[1].

Python website has since added another download link written in Chinese on their website.

Hah! I didn't know that since I don't use Python, but I agree with the speculation of that blocking!

When PHP announced that they will skip PHP6, we joked that it is a smart move to avoid PHP version 6.4
