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, which was necessary to keep compatiblity with JDK 14.

“Guava shaded” refers to issue OAK-10323, which was necessary to remove all API usages of the Guava library (Oak now internally uses a shaded copy of Guava, which is not visible in Oak APIs anymore).
