+Cajon is written in Kotlin 1.7.
 
 Cajon is probably the only plugin that uses JUnit 5 Jupiter for unit testing so far (or at least the only one I'm aware of ;) ).
 The IntelliJ framework actually uses the JUnit 3 TestCase for plugin testing, and it took me quite a while to make it work with JUnit 5.
 Feel free to use the code (in package ```de.platon42.intellij.jupiter```) for your projects (with attribution).

+      I spent several days trying to figure out what is going on, but I'm giving up on this pile of crap called IntelliJ.

+    <ul>
+      <li>API change in IntelliJ platforms now requires minimum version 2019.3.1. Sorry, giving up to maintain compatibility after four attempts.
+      <li>Maintenance. Updated various dependencies (Kotlin 1.7.10) and AssertJ 3.23.1 and AssertJ-Guava 3.5.0.
+      <li>Tried to fix unreproducible issue #9.
+      <li>Added AssertThatIsZeroOne inspection demanded by issue #5.
