I found a MariaDB, Jira page that tracks defects/features:

https://mariadb.atlassian.net/projects/MDEV?selectedItem=com.atlassian.jira.jira-projects-plugin:release-page

Today (June 17) 10.2 has the following stats:
    4 - done
   11 - in progress
  134 - to do

so it looks like the 10.2 release is not just around the corner.

If anyone wants to add 10.0 that would be useful. I'll probably
check back in a month to see how 10.2 is going...
