The most important upgrade is babel 5 to 6 (updated configuration and dependencies).
Fixing the systemjs-route-bundler configuration by the way (the release task doesn't seems to be entirely fixed, but it was already broken in the current version, and I have no interest in that part since I'm migrating to the component router).
Some tasks could need some more tests and fix, since I focused on having a running projet with a working "start" script, not to fix all gulp related issues (like tests).
Upgrades all jspm and npm dependencies.
