Using latest IJ 2021.1 that came out today. I select JDK 14 and then advance through the wizard and it only gives me option to go up to 13. Is that a bug?

thats the target vm of the bytecode. iirc kotlin only uses bytecode up to version 13 for now.

Interesting... What should I use? I remember reading that you need to use jdk 14 in order to build dmgs, etc. But 11 is min supported jdk for compose desktop. Should I select target jvm 1.8 or 11 then?

i would recommend 11

It is completely normal to have bytecode targeting a lower version than the JDK or JRE in use
