percolate:migrations

Supports both up and down functions for each migration, allowing easy rollbacks as demonstrated in the README with examples like migrating to version 0 to undo all changes.

Prevents multiple app instances from running migrations simultaneously, ensuring data consistency in clustered deployments, which is highlighted in the README's error handling section.

Fully supports Meteor's async/await patterns, with README examples showing how to use Meteor.wrapAsync or direct async functions from Meteor 2.8+ for asynchronous operations.

Allows using a custom MongoDB collection for migration tracking, useful for multi-app database scenarios as noted in the configuration options.
