3.2.1 release notes
---------------------------------------
- Import Path Change: See MIGRATION_GUIDE.md for tips on updating your code
Changed the import path from github.com/dgrijalva/jwt-go to github.com/golang-jwt/jwt
- Fixed type confusion issue between string and []string in VerifyAudience.
This fixes CVE-2020-26160
3.2.2 release notes
---------------------------------------
- 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.
- 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.
- Added support for EdDSA / ED25519.
- Optimized allocations.
