The comments on the left side refer to backwards-incompatible changes, which,
by default, are not ported to maintenance branches.

"JDK 14 comp" refers to issue [OAK-7358](https://issues.apache.org/jira/browse/OAK-7358),
which was necessary to keep compatiblity with JDK 14.

"Guava shaded" refers to issue [OAK-10323](https://issues.apache.org/jira/browse/OAK-10323),
which was necessary to remove all API usages of the Guava library (Oak still
uses a shaded copy of Guava internally, which is not visible in Oak APIs anymore).
