 ## ⚠️ Limitations
 
-- Due to Fiber's usage of unsafe, the library may not always be compatible with the latest Go version. Fiber v3 has been tested with Go versions 1.21 and 1.22.
+- Due to Fiber's usage of unsafe, the library may not always be compatible with the latest Go version. Fiber v3 has been tested with Go versions 1.22 and 1.23.
 - Fiber is not compatible with net/http interfaces. This means you will not be able to use projects like gqlgen, go-swagger, or any others which are part of the net/http ecosystem.
