Node.js 10.x with long therm support has been released
Thats’s misleading. The announcement states, it “will become the new active Long Term Support release line”. According to the schedule LTS start is planned for October 2018. So, the LTS version for the next 6 months is v8.
EDIT: While v10 has already passed the development stages (v9), I expect it will require a few more weeks to mature, the new ABI in particular. The N-API is said to add ABI-stability which should simplify the job for maintainers of modules with native code integration. It is a bit of an irony Nodejs required 7 major releases as they say (btw, I am counting to get the ABI right, and that’s just a promise for now. We will see.
