See <https://issues.apache.org/jira/browse/OAK-7182>.
- We now support building and running with versions 15.0 to 20.0 (property "guava.version")
- There's a build profile to build with the latest instead of the oldest ("guava-latest", <https://issues.apache.org/jira/browse/OAK-7399>)
- we test that on <https://builds.apache.org/job/Apache%20Jackrabbit%20Oak%20matrix/>)
- import packages now declare a range "[15.0,21)", defined in oak-parent/pom.xml (<https://issues.apache.org/jira/browse/OAK-7406>)
Version 21.0 and newer will require more work, both because there's more code that we'll need to change (see <https://issues.apache.org/jira/browse/OAK-7182?focusedCommentId=16354061&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16354061>), and because the solr version that we use would break.
Best regards, Julian
