// Anytime you change the schema of one of the collection in a non-backward
// compatible way you have to write a migration in this file using the following
// API:
//
//   Migrations.add(name, migrationCallback, optionalOrder);

// Note that we have extra migrations defined in `sandstorm.js` that are
// exclusive to Sandstorm and shouldn’t be executed in the general case.
// XXX I guess if we had ES6 modules we could
// `import { isSandstorm } from sandstorm.js` and define the migration here as
// well, but for now I want to avoid definied too many globals.

// In the context of migration functions we don't want to validate database
// mutation queries against the current (ie, latest) collection schema. Doing
// that would work at the time we write the migration but would break in the
// future when we'll update again the concerned collection schema.
//
// To prevent this bug we always have to disable the schema validation and
// argument transformations. We generally use the shorthandlers defined below.
