The first point. It has been slimmed down. The new version of QQ is only 14M in size and no longer includes Tencent TM and Tencent TT browsers. This is the first time that QQ has been reduced in size since its inception.

The functions such as super video, geographical location sharing, weather forecast, security center, address book, QQ live broadcast, and QQ music previously disclosed by Tencent have been implemented one by one.

Features that I am more interested in:

Security Center, QQ2005 Beta3 has set up special protection measures for the two most common ways that affect PC security-unsafe links and executable file injection. For unsafe URL links that appear in QQ messages, QQ2005 Beta3 will directly filter out through the "QQ Security Center" to minimize the chance of users receiving unsafe links; users can also directly report to the "QQ Security Center" when receiving suspicious links to protect the information security of themselves and other QQ users. At the same time, QQ2005 Beta3 has added a file transfer security level setting. The default setting for the transfer of executable files is prohibited to reduce the risk of users receiving and activating viruses; users can also reduce the file transfer security level in the security settings to allow the transfer of executable files.

Support real-time display of music status. When you see your friends listening to your favorite song on QQ, you can easily click and share it with your friends. You can share it with your friends in real time.
