Overview

Implements Part 5 of the multi-version SDK support for mx-platform-node, enabling the same npm package to publish multiple API versions as independent major versions:

• mx-platform-node@2.x.x = API v20111101
• mx-platform-node@3.x.x = API v20250224

Key Changes

Infrastructure Updates

• Updated supporting scripts (clean.rb, version.rb) for multi-version operations, remove ability to bump major version
• Added version_directory parameter to publish.yml and release.yml workflows
• Implemented matrix-based job execution in on-push-master.yml for parallel version handling

Automation Improvements

• Enhanced generate.yml with version selection dropdown and update bump version to add skip and remove major as option
• Updated generate_publish_release.yml with matrix strategy and add commit SHA support for OAS file retrieval
  • this bypasses CDN cache race condition where SDK is generated with cached url that has no changes
• Added skip-publish safety flag to prevent spurious publishes during structural changes

Templates & Documentation

• Updated package.mustache to include new apiVersion field and description for consumer discovery
• Updated README.mustache with API version identification section
• Updated MIGRATION.md with v20250224 upgrade path
• Added Documentation - Implementation guides, troubleshooting, and workflow references

Directory Structure

• Migrated latest/ → v20111101/ to align with semantic versioning
• Staged with [skip-publish] flag to prevent publish during structural change

Testing

• Ready for GitHub Actions testing on merge
• Integration testing with openapi repository dispatch to follow
