Truffle Unchained – Portable Language Runtimes as Java Libraries (medium.com)

This will boost adoption at so many levels: - Importing a Truffle language as a regular Maven dependency - Ease integration with mainstream package managers - Ability to update to the latest language version, independently of the JVM used

I'm still in awe at how smooth the Truffle "unchaining" worked out with no API changes (just a few necessary additions).
