+This version uses Gradle 7.6.2, which is probably the last 7.x release. It took a while, but Gradle 8.x is in
+another branch of this repo and is much more stable now than it was at the start of 2023. Because Gradle 8.3
+is fully compatible with Java 20 (Gradle 7.x is not), and people may try to compile with Java 20, you may want
+to switch to the 8.x branch. If you have Gradle plugins that are only compatible with 7.x, though, feel free
+to stay using this branch; it's been battle-tested and works fine.
