[Unreleased]

1.4.0 - 2026-10-19

Added

  • Added cross-compilation support for Scala 3 to prepare compatibility with future Kafka versions.

Changed

  • Updated SAP JCo to 3.1.13.
  • Retry handling and retry log messages are now consistent across all connectors. Log messages no longer start with the class name. If you filter or alert on log patterns, check them.
  • Configuration validation is faster for connector instances with many connections.
  • When all retries are exhausted, the log now includes the cause of the last failure.

Removed

  • Removed the configuration sap.rfc.schema.compat.version.

Fixed

  • Connector properties that use a config provider (e.g. ${file:…}, ${vault:…}) are no longer re-resolved on every poll/put, which reduces load on the secret store.
  • Fixed conversion of BCD/decimal fields inside nested arrays.
  • Requests that fail because the JCo destination is no longer valid (JCo error group 180) are now always retried immediately.
