+`raven-node` supports only LTS versions of Node, therefore currently required release is `>= v4.0.0`.
+The last known working version for `v0.10` and `v0.12` is `raven-node@2.1.2`.
+Please use this version if you need to support those releases of Node.

+To see up-to-date Node.js LTS Release Schedule, go to https://github.com/nodejs/LTS.
