Plans for MariaDB 10.5
MariaDB 10.5 will be the next major development release.
We manage our development plans in JIRA, so the definitive list will be there. This search shows what we currently plan for 10.5. It shows all tasks with the Fix-Version being 10.5. Not all these tasks will really end up in 10.5, but tasks with the "red" priorities have a much higher chance of being done in time for 10.5. Practically, you can think of these tasks as "features that will be in 10.5". Tasks with the "green" priorities probably won't be in 10.5. Think of them as "bonus features that would be nice to have in 10.5".
