Recently as part of the regular upstream patching cycle, the Golang team has released two new patch versions:

• go1.21.5 (released 2023-12-05) includes security fixes to the go command, and the net/http and path/filepath packages, as well as bug fixes to the compiler, the go command, the runtime, and the crypto/rand, net, os, and syscall packages. See the Go 1.21.5 milestone on our issue tracker for details. 
• go1.20.12 (released 2023-12-05) includes security fixes to the go command, and the net/http and path/filepath packages, as well as bug fixes to the compiler and the go command. See the Go 1.20.12 milestone on our issue tracker for details. 

This issue tracks testing and bumping the current in-tree dev-lang/go autogen to these new patch versions for all Funtoo users.
