The document discusses the growth and development of the Node.js community and project. It notes that the number of contributors has grown from 14 to 85 in a year and a half. It also outlines improvements made to stability, standards support, language features, debugging tools, and the goal of a new installer. Overall the document conveys that Node.js has expanded its community involvement while focusing on increasing stability, performance, and standardization.

2. Community.
Gemeenschap. Communauté. Comunidad.
When I first got involved with Node.js Core, there were 14 active participants
(not counting everyone involved in io.js)
Up to that point, Node.js had 681 contributors over it's lifetime.

3. Gemeenschap. Communauté. Comunidad
Just over a year and a half later, there are 85 contributors with commit
access to the main repository (with more added regularly)
The contributors list now tops 1084 individuals.

5. Stability.
Stabilität. Stabiliteit. Cobhsaíochta.
There have been 2.7k+ commits on master since v4.0.0
49% focus on improving documentation, tests and benchmarks.
15% focus on updated tooling, build and dependencies.
17 semver-major commits in v5
90 semver-major commits in v6

6. Stability.
Stabilität. Stabiliteit. Cobhsaíochta.
As soon as we made it easier for the community to
contribute to Node.js,
That community immediately began working to make
Node.js more secure, stable, and performant.

Canary in the Goldmine
With citgm, we are now proac6vely
running tests for 68 of the most depended
on modules in the Node.js ecosystem –
catching regressions before they happen.

Running all semver-major changes through
both CI and citgm before they land is now
standard prac6ce.

and go see his talk!)

Promises
async await
ES6 Modules
Node.js v7 should ship with V8 5.4

23. Language standards.
Normes Langage de programmation.
async await is coming.
(we just don't know when)
We have some work to do on Promises still.
(Namely, making Promises compatible with
Node.js Debugging and making the Node.js
API compatible with Promises)

24. Language standards.
Normes Langage de programmation.
ES6 Modules are a difficult, non-trivial problem.
Significant effort is going into getting it right.
It will happen, but may take some time.
(and a big shout out to @bradleymeck for leading the way)

25. Language standards.

The Node.js Core Team is exploring how to better
engage with TC-39 to ensure that new JavaScript
language features meet the needs of Node.js users.
