pkg/js/v0.2.1

v0.2.1 (2026-02-11)

Added:

• Add helper methods for validating schema versions & checking if a particular model is modular (#534)
  • Add SchemaVersion enum to represent valid schema versions
  • Add isSchemaVersionSupported, checkSchemaVersionSupportsModules, and getSchemaVersionFromString utility methods
  • Add isModelModular utility method to check if a model is modular based on its schema version and definition

Changed:

• ⚠️ [BREAKING] Drop support for Node.js v16 & 18. We recommend updating to a node-runtime that is supported upstream - currently 20 (maintenance), 22 (maintenance), 24 (LTS) and 25 (current).
  The minimum supported version of Node.js is now v20.19.0. This is in line with our stated supported environments.
