What is the difference between v1 and v2?

[gouguoyin]

There is no difference between v1 and v2 of the API, but the implementation of the translation resource files in language.go is different. The v1 is implemented by the third-party extension library packr, and the v2 is implemented by the standard library embed after golang1.16. If your golang version is 1.16+, the v2 is recommended, otherwise, the v1 is required.
