Finally, node v4!

A brief timeline

• 1995 : JavaScript
• 2008 : V8
• 2009 : Node.js

A brief timeline

• March 2013 : Node.js 0.10
• December 2014 : io.js

2015: io.js VS node.js

• January 2015 : io.js 1.0
• February 2015 : Node 0.12
• February 2015 : Node.js foundation
• July 2015 : Merge announcement

And finally

• September 2015 : Node.js 4.0.0
• Today : Node.js 4.1.1
• Next month and beyond: Node.js 4.x.x, Node.js 5.x.x

Why "node v4"?

• io.js was at 3.0
• New semantic versioning

What's new? (since node 0.12)

• Massive V8 upgrade (3.28 --> 4.5)

which results in...

What's new? (since node 0.12)

• Performance upgrades

• Lots of ECMAScript 2015 features! \o/

  • Arrow functions
  • Generators
  • let, const
  • Destructuring
  • Methods
  • Classes
  • etc

Should I upgrade?

... But check your native dependencies before doing it.

The future

Frequent releases, Long Term Support.

Thank you!
