@msfroh @aparajita31pandey this should allow you to use dependencies={ opensearch: "^3.1.0" } for the whole 3.x line.

Also FYI, that syntax also supports defining ranges like this: dependencies={ opensearch: "[3.0.0, 3.4.0)" }

If a plugin ever relies on extension points marked @opensearch.experimental, then expect changes from one minor version to the next until the experimental label is removed. In this case, ActionPlugin is not experimental so adding the previous extension point back in for bwc.
