 Guava provides two different "flavors": one for use on a (Java 8+) JRE and one
 for use on Android or Java 7 or by any library that wants to be compatible with
 either of those. These flavors are specified in the Maven version field as
-either `28.1-jre` or `28.1-android`. For more about depending on

-1. APIs marked with the `@Beta` annotation at the class or method level
-are subject to change. They can be modified in any way, or even
-removed, at any time. If your code is a library itself (i.e. it is
-used on the CLASSPATH of users outside your own control), you should
-not use beta APIs, unless you [repackage] them. **If your
-code is a library, we strongly recommend using the [Guava Beta Checker] to
-ensure that you do not use any `@Beta` APIs!**
