<!--
This is the Mixxx schema history file. It keeps track of internal changes to the
Mixxx database schema and allows Mixxx to automatically upgrade itself to new
revisions of the schema on a version upgrade.

DO NOT EDIT THIS FILE OR YOU WILL BREAK YOUR MIXXX LIBRARY AND LOSE YOUR
METADATA

Backwards compatible migrations are required to be "reappliable" safely
after the database has been opened and used with an older Mixxx version!!
Backward compatible schema migrations must ensure that they do not fail
on a newer schema version and that they neither overwrite nor delete
any existing data. If this is not possible then a migration does not
qualify to be backwards compatible. In this case the min_compatible
attribute has to be set to the current version, i.e. the same version
as the migration.

Errors when adding table columns that already exist when reapplying a
migration are gracefully ignored during schema migration to allow
reapplying those migrations.
