From dcdee5e2aa05ec07e7e750bea4faad63bce7b668 Mon Sep 17 00:00:00 2001 From: Sebastien Douheret Date: Tue, 23 Jan 2018 15:31:00 +0100 Subject: Reworked SDKs events (introduced sdk-state-change) Split add/remove/state-change from installing output (AKA SDKManagement event) in order to clearly separate events used to send installation output and sdk config changes.
