Seagull 7.2.1 is now the fastest Draft 2020-12 validator in the JavaScript ecosystem, specifically excelling in scenarios requiring unevaluatedProperties and complex if/then/else branches. How to Migrate to Seagull 7.2.1 If you are currently on Seagull 7.x, the migration is mostly painless. However, if you are coming from version 6.x or earlier, breaking changes exist. From 7.2.0 → 7.2.1 (Simple update) Run your package manager of choice:
npm install seagull@7.2.1 # or yarn add seagull@7.2.1 Due to the fix in circular references, you might now receive CIRCULAR_REF errors that were previously silent. This is a good thing—it prevents undefined behavior. Update your error handlers to catch this new error code. The most significant change is the removal of the $data keyword (JSON Schema extension for data references) in favor of native $dynamicRef . Also, the asynchronous API has changed: Seagull 7.2.1
