Calcite 1.15.0 was released on December 11 (more than two months ago). We have solved over 50 issues since then, hence I think we should start discussing about releasing Calcite 1.16.0 (I can be release manager if nobody else steps up).
I have created [1] to keep track. CALCITE-2027 (dropping JDK7 support) was targeted for 1.16.0. Julian, Michael, you have been working on that issue, could you share the current status? Any other particular features that people would like to include? -Jesús [1] https://issues.apache.org/jira/browse/CALCITE-2181
