5.16 Release notes

Upgrade guides

• Upgrading on IIS
• Upgrading on Kubernetes

Release date

Cinchy v5.16 was released on May 21, 2025.

Important changes

• Due to changes in encryption and certificate validation behavior, existing connection strings will be updated (once off) to include Trust Server Certificate=true. This is to preserve existing behaviour, i.e. encryption without certificate validation. If you use a TLS connection with a certificate provisioned on a server, manually remove this directive from the connection strings to enable certificate validation. For new connection strings, this directive should be added to skip certificate validation, or omitted to require it.
• Latest supported EKS and AKS versions updated to v1.32.

Enhancements

• Topics in Kafka real-time syncs now have individual consumer groups; this allows for more stable rebalancing when the load increases/decreases.

warning

To prevent data loss in your real-time syncs when upgrading to v5.16, we recommend that you:

1. Navigate to the [Cinchy].[Listener Config] table and disable all listener configs.
2. Wait until all Kafka messages are processed by the worker.
3. Perform your Cinchy upgrade.
4. Re-enable your listener configs.

Bug fixes

• Fixed a regression (introduced in v5.11) in the Connections CLI whereby the -l short option would specify a PAT rather than a delimiter.
• Columns with JSON data that are synced into Kafka Topic destinations will be correctly formatted when SchemaRegistryConfig is disabled and the data is configured to be a JSON object.
