-## Migration Guide (v3.2.1)
-
-Starting from [v3.2.1](https://github.com/golang-jwt/jwt/releases/tag/v3.2.1]), the import path has changed from `github.com/dgrijalva/jwt-go` to `github.com/golang-jwt/jwt`. Future releases will be using the `github.com/golang-jwt/jwt` import path and continue the existing versioning scheme of `v3.x.x+incompatible`. Backwards-compatible patches and fixes will be done on the `v3` release branch, where as new build-breaking features will be developed in a `v4` release, possibly including a SIV-style import path.
-
-### go.mod replacement
-
-In a first step, the easiest way is to use `go mod edit` to issue a replacement.
-
-```
-go mod edit -replace github.com/dgrijalva/jwt-go=github.com/golang-jwt/jwt@v3.2.1+incompatible
-go mod tidy
-```
-
-This will still keep the old import path in your code but replace it with the new package and also introduce a new indirect dependency to `github.com/golang-jwt/jwt`. Try to compile your project; it should still work.
-
-### Cleanup
-
-If your code still consistently builds, you can replace all occurences of `github.com/dgrijalva/jwt-go` with `github.com/golang-jwt/jwt`, either manually or by using tools such as `sed`. Finally, the `replace` directive in the `go.mod` file can be removed.
-
-## Older releases (before v3.2.0)

 **SECURITY NOTICE:** It's important that you [validate the `alg` presented is what you expect](https://auth0.com/blog/critical-vulnerabilities-in-json-web-token-libraries/). This library attempts to make it easy to do the right thing by requiring key types match the expected alg, but you should take the extra step to verify it in your usage.  See the examples provided.
 
+### Supported Go versions
+
+Our support of Go versions is aligned with Go's [version release policy](https://golang.org/doc/devel/release#policy).
+So we will support a major version of Go until there are two newer major releases.
+We no longer support building jwt-go with unsupported Go versions, as these contain security vulnerabilities
+which will not be fixed.

+* Introduces support for Go modules. The `v4` version will be backwards compatible with `v3.x.y`.
+
+#### 3.2.2
+
+* Starting from this release, we are adopting the policy to support the most 2 recent versions of Go currently available. By the time of this release, this is Go 1.15 and 1.16 ([#28](https://github.com/golang-jwt/jwt/pull/28)).
+* Fixed a potential issue that could occur when the verification of `exp`, `iat` or `nbf` was not required and contained invalid contents, i.e. non-numeric/date. Thanks for @thaJeztah for making us aware of that and @giorgos-f3 for originally reporting it to the formtech fork ([#40](https://github.com/golang-jwt/jwt/pull/40)).
+* Added support for EdDSA / ED25519 ([#36](https://github.com/golang-jwt/jwt/pull/36)).
