+# Seldon Core Release 1.19.0 (Draft Release)
+
+A summary of the main contributions to the [Seldon Core release 1.19.0](https://github.com/SeldonIO/seldon-core/releases/tag/v1.19.0-rc.1).
+
+### 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.
+
+:warning: Note: Be aware of the changes to the [Bitnami public catalog](https://github.com/bitnami/charts/issues/35164) 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](https://docs.seldon.ai/seldon-core-1).
+
+### 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.

 If you were running our Openshift 0.4.2 certified operator and are looking to upgrade to our 1.1 certified operator, you will also need to follow the "upgrading process" steps in the "Upgrading to 0.5.2 from previous versions" section.

+
+## Upgrading to 1.19
+
+**Python 3.12 Adoption**
+All core Python components — including prepackaged servers, Alibi Detect/Explain servers, wrappers, notebooks, and E2E tests — now target Python 3.12.
+
+What this means:
+- Wheels or dependencies not yet compatible with Python 3.12 may fail at runtime.
+- Custom inference images built against older Python versions must be rebuilt and tested.
+
+**Deprecated and Removed Components**
+- Analytics Helm chart is no longer built.
+- GPU-related files deprecated.
+- OpenVINO references removed (except for deprecated charts).
+
+Impact:
+- Users relying on deprecated components should plan migration.
+- No supported upgrade path for removed experimental artifacts.
+
+**Kubernetes Compatibility**
+- Operator tests validated against Kubernetes 1.23 to 1.35.
+- No removal of older supported Kubernetes versions announced, but forward compatibility is improved.
+
+**Operator**
+It is primarily a hardening and modernization release, not a feature-driven one.
+
+**Autoscaling (KEDA)**
+- KEDA was upgraded to align with Go dependencies.
+- While tests pass, clusters running older KEDA installations may behave differently.
+
+**Helm Value Drift**
+Operator config maps were aligned with Helm values.
