Release 1.19.0 Highlights

A summary of the main contributions to the Seldon Core release 1.19.0.

Overview

This release focuses on platform maintenance, security hardening, and ecosystem modernization. The main themes are extensive CVE remediation, a broad upgrade to Python 3.12 across images and tooling, dependency and base image refreshes, CI and workflow improvements, alongside documentation cleanup and migration work. No major new end-user features are introduced, but the release materially improves security posture, test coverage, and long-term maintainability.

Security and CVE Fixes

• Multiple CVEs addressed across Go, Python, and container images, including the operator, executor, alibi-detect server, python-builder, and core builder images.

• Go runtime updated to a newer patch release to address known vulnerabilities.

• Autoscaling dependencies updated to remediate CVEs in the KEDA library.

• RClone upgraded and base images refreshed to address container-level CVEs.

Dependency and Runtime Upgrades

• Python upgraded to Python 3.12 across:

  • Prepackaged servers

  • Alibi Detect and Alibi Explain servers

  • Python wrappers

• Conda base images migrated from Miniconda to Miniforge(OSS).

• UBI base images aligned and refreshed (UBI 9.7 where applicable).

• Protobuf, gRPC, Poetry, and other build-time dependencies updated.

• Kubernetes compatibility testing expanded to include Kubernetes 1.35 (1.23.x to 1.35.x).

Images and Build System

• SBOM generation added to Docker image builds for improved license and supply-chain visibility.

• Deprecated GPU-related Docker images for the Python wrapper and both Alibi servers.

⚠️ Note: Be aware of the changes to the Bitnami public catalog as they impact few examples in the documentation.

Licensing and Compliance

Regeneration and cleanup of license metadata.

Helm, Operator, and Configuration Changes

• Deprecated analytics Helm chart excluded from build workflows.

• Keda dependency upgraded to 2.17.3 and forward-compatible with 2.18.3(latest).

Documentation

Documentation was migrated to GitBook. It can be found here.

Deprecations and Cleanup

• GPU-related files formally deprecated.

• Several examples and charts removed or disabled including:

  • "MLOps with Seldon and Jenkins Classic" notebook

  • "End-to-end MLOps with Seldon Core and Jenkins X" notebook

  • GPU examples and notebooks

  • Legacy Alibi Detect and Explain examples

Backward Compatibility

• No intentional breaking API changes introduced in this release candidate.

• Users should validate custom images and notebooks against Python 3.12.

• Operators upgrading from older releases should review image and base-OS changes.
