 It can be tricky to migrate from older versions of Marlin as settings change. Marlin checks for old settings and tells you what to change during the build, but the final result is never fully up to date. Wouldn't it be nice if Marlin would automatically migrate old settings to a new configuration for you?
 
-We're currently working on tools to improve the situation, with the goal to build a schema and a database of configurations across all Marlin versions so we can generate complete configuration headers, perform migrations, and even generate searchable documentation for this website.

   - During the testing period all development within `dev` will take the lead from the pre-release branch, so nothing will go into `dev` that isn't also going into the pending release. New features and other non-bug-fixing PRs will be held during this period.
   - Once the pre-release is certified by testers (or at least hasn't exploded dramatically) it will be tagged and released to the world.
   - Releases may be followed up with "fixup" patches within the first week after a release. Volunteer testers catch a lot of bugs, but they don't always catch 'em all!
