* Remove client metadata from AnyTLS requests by default **1**
* Fixes and improvements

**1**:

We found that the AnyTLS client implementation uploads metadata that is **not used by the open-source server**, and there are reports of vendors using it to profile and discriminate against users. We now leave it empty by default and allow you to customize it, see [AnyTLS client metadata](https://sing-box.sagernet.org/manual/misc/anytls-client-metadata/).
