+Since 1.8 the Go Routine ID is present in json (`r` field) or colorized log output (for multi threaded server types).
 
 Optional additional `KeyValue` pairs can be added to the base structure using the new `log.S` or passed to `log.LogRequest` using `log.Attr` and `log.Str`.
 
 If console output is detected (and ConsoleColor is true, which is the default) or if ForceColor is set, colorized output similar to `logc` will be done instead of JSON. [levelsDemo/levels.go](levelsDemo/levels.go) produces the following output:
