Even though delve is showing the difference between nil slices, and zero-len/zero-cap slices, the VSCode interface to the debugger is not doing so, and I appear to have the recent 0.11.7 release.
I also only have a single dlv.exe on my system of ver 1.2.0

Delve showning nil vs zero-len/zero-cap slice

VScode Go extension not showing the difference

Test code:

package main import "fmt" func main() { var x []string y:=[]string{} fmt.Println(x,y) }
