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

• go1.20.3 (released 2023-04-04) includes security fixes to the go/parser, html/template, mime/multipart, net/http, and net/textproto packages, as well as bug fixes to the compiler, the linker, the runtime, and the time package. See the Go 1.20.3 milestone on our issue tracker for details. 
• go1.19.8 (released 2023-04-04) includes security fixes to the go/parser, html/template, mime/multipart, net/http, and net/textproto packages, as well as bug fixes to the linker, the runtime, and the time package. See the Go 1.19.8 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.
