+### [Go Security Releases](/doc/devel/release)
 
 Release notes for past security problems. Per the [release
-policy](https://go.dev/doc/devel/release#policy), we issue security fixes to

 The main documentation page for Go native fuzzing.
 
-Fuzzing is a type of automated testing which continuously manipulates inputs to
-a program to find bugs. Go supports fuzzing in its standard toolchain beginning
-in Go 1.18. Native Go fuzz tests are [supported by
-OSS-Fuzz](https://google.github.io/oss-fuzz/getting-started/new-project-guide/go-lang/#native-go-fuzzing-support).
