Node v0.10.0 (Stable)
Node v10.10.0 (Stable) has been released this week with a focus on an improved "Stream" API called "Stream2". This is a major change since a lot of the Node APIs rely on "Stream2"
Another interesting insight is the upcoming releases: v0.12 will focus on improving the HTTP (which is already quite good) and the long waited for v1.0 - which will not have many changes in regards of day-to-day operations but will rather mark a significant milestone in terms of stability.
