This is the New & Noteworthy page for CDT 10.0 which is part of Eclipse 2020-09 Simultaneous Release

Java 11 or later required to run CDT

Starting with CDT 10.0 Java 11 or later is required to run CDT. This align with requirements of Eclipse IDE which also requires Java 11 to run starting in 2020-09.
