## Supported Go versions
|
|
|
|
|
|
As of version 4.0.0, Echo is available as a [Go module](https://github.com/golang/go/wiki/Modules).
|
|
|
Therefore a Go version capable of understanding /vN suffixed imports is required:
|
|
|
|
|
|
- 1.9.7+
|
|
|
- 1.10.3+
|
|
|
- 1.14+
|
|
|
|
|
|
Any of these versions will allow you to import Echo as `github.com/labstack/echo/v4` which is the recommended
|
|
|
way of using Echo going forward.
|
|
|
|
|
|
For older versions, please use the latest v3 tag.
