@christophehurpeau Thanks for your contribution. What use case did you have in mind? Filters and Reformatters will be dropped in next major so I think if there's a workaround for this right now it might be better to wait. /cc: @indexzero @jcrugzz

I'm trying to add a label in the logger and add it to all messages, no matter the transport.
You can see it here : https://github.com/christophehurpeau/springbokjs-logger/blob/4.0/src/index.js#L31

This is something we could consider before 2.0.0

This has been cherry-picked and will land in winston@1.1.0 later today.
