Just a heads up - if you use VSCode for binding development, JDK11 will soon be required (I just started to get popups on the warning). openHAB 3.0 come on…
EDIT: this is part of the update to the java development kit for VSCode that brings all sorts of improvements (alot more refactorings, performance, maven enhancements, etc). Sadly - still no support for nullable attributes in the IDE (although if you google, there is an unofficial way to enable them)
