*Reminder to the contributor / reviewer of the PR*: please note that the code
deadline for 1.0.0 is less than 2 weeks away (Oct. 4th). Please re-evaluate
your JIRA and see if it still makes sense to be merged into 1.0.0 or it could
be pushed out to 1.1.0, or be closed directly if the JIRA itself is not valid
any more, or re-assign yourself as contributor / committer if you are no longer
working on the JIRA.
