We are pleased to announce the release of version 2.9.4 of OPC Publisher and the companion web api service. This release comes with several bug and security fixes and is the latest supported release.

Breaking changes in 2.9.4

IMPORTANT. Please read when updating from previous versions of OPC Publisher

  • Arm64 and AMD64 container images are published now with Mariner (Azure) Linux (distroless) as base images instead of Alpine.
  • Arm32 (v7) images of OPC Publisher continue to use Alpine as base image. Support transitions to the same model as for "preview" features. Security updates are released as a result of updates to the AMD64 and ARM64 version of OPC Publisher.
  • Swagger UI has been removed without replacement.
