including hooks to enable bootstrapping of web applications while offline.

Service Worker
So what is all of this good for? Powerful offline / mobile support!
- Detect when offline and serve from cache
- Build your own selective cache based on resources requested
- Prefetch resources in the background (e.g. responsive images)
- ServiceWorker-side templating

Bottom Line
- Not yet ready for prime time, but coming along
- Could still be useful today for specific use cases
Is
ServiceWorker Ready?
Potentially-breaking changes:
- Simplified .show() and .hide() logic
- Changed .data() to more closely match the dataset spec
- $.Deferred is now fully Promises/A+ compatible (major changes
to how the existing .then() method works and handles errors)
- Removal of "special-case" Ajax methods (e.g. .abort())
- And more!
Migrate plugin provided to ease transition
Meteor
1.2 ("later this summer")
- Adopting ES2015 as the "official JavaScript" of Meteor!
- Auto-transpiling via Babel
- First-class support for "reactive" rendering via Angular and JSX
And now for something completely different...
