T5.3.19 Update

The T5.3.19 Update: What's New and How it Impacts Your Business

• Deprecation of Legacy Endpoints: REST endpoints /api/v2/legacy/sync and /api/v2/legacy/bulk are officially deprecated with full removal scheduled for T6.0. T5.3.19 returns a Deprecation header and a 299 status code for these calls.
• GraphQL Federation: The update adds native support for Apollo Federation 2.0, allowing subgraphs to be composed more efficiently.
• Webhook Retry Logic: A new exponential backoff algorithm (starting at 5 seconds, capping at 300 seconds) replaces the previous fixed-interval retry, reducing downstream spam.

The T5.3.19 update has received generally positive feedback, though opinions vary by segment:
