Should Express 5.0 require a minimum of Node.js 4?
Problem
This is a discussion regarding having Express 5.0 drop support for Node.js 0.10. One of the reasons for the delay in Express 5.0 was the announcement of the official merging of Node.js and io.js, and we were looking forward to it's outcome to determine what we should do with Express 5.0. Here at Express, we value very long-lived major versions, allowing users to confidentially build their new server on Express and not have to worry about needing to upgrade across a major, breaking change for years. Express 4.0 has been out for over a year now and Express 3.0 was supported for over 3 years !! When Express 5.0 comes out, Express 4.x line will continue to be fully supported, delivering our users bug fixes, new features, and more! To this end, we have been carefully watching io.js/Node.js in relation to Express 5.0 such that we can continue this great support history without accidentally locking us into the past for a long time. Please share your thoughts here.

1 Fix
Update Express 5.0 to Require Node.js 4 or Higher
Express 5.0's support for older Node.js versions (specifically 0.10) limits the ability to utilize modern JavaScript features and performance improvements introduced in later Node.js versions. Dropping support for Node.js 0.10 will allow Express to leverage the latest language features and security enhancements, ensuring better performance and maintainability.
