#### 1.2-beta10

* Add multiple configuration support **1**

*1*:

Now you can pass the parameter `--config` or `-c` multiple times, or use the new parameter `--config-directory` or `-C` to load all configuration files in a directory.

Loaded configuration files are sorted by name. If you want to control the merge order, add a numeric prefix to the file name.

message, see [TLS#ECH](/configuration/shared/tls#ech).

In previous releases, WireGuard outbound support was backed by the lower performance gVisor virtual interface.

It achieves the same performance as wireguard-go by providing automatic system interface support.

It does not depend on gVisor and has better performance in some cases.

It is less compatible and may not be available in some environments.
