Key highlights
Enhanced Security and Future-Ready Safeguards
With the Managed Fusion 5.9.9 release, we’ve upgraded Kafka to version 3.7.0, incorporating the latest security updates to strengthen your platform’s resilience. Additionally, we’ve implemented critical updates for Managed Fusion’s Webapps, Templating, and API Gateway services, ensuring robust protection for your data. Looking ahead, we’ve introduced enhancements to streamline and expedite the delivery of future security updates, providing you with a safer Managed Fusion environment.Secure deployments with immutable root file system
Fusion now supports a read-only root file system to safeguard against unauthorized modifications, protecting your deployment against malicious software and other attacks. Most services operate efficiently in this mode, and for components that need write access, a separate writable mount is available. Read-only mode is enabled by default for some Managed Fusion services. See Read-only root file system for a list of services that support it or have it enabled by default. It should only be enabled for services that do not require CRUD access. Contact Lucidworks to customize how read-only root file system access is configured for your Managed Fusion deployment.Bug fixes
- This release improves compatibility between Solr and Managed Fusion’s LWAI Prediction index pipeline stage to prevent errors about incompatible characters in field names.
-
The Managed Fusion API realm can now authenticate when an API key is passed via an
apiKeyparameter. Previously, the key could only be passed in the header, as in these examples:Now you can also pass the key as a parameter, like this: - The Configurations and ZooKeeper Import/Export APIs are now accessible only to authorized users from within Managed Fusion.
Known issues
- Saving large pipelines during high traffic may trigger service instability. In some environments, saving large query pipelines while handling high traffic loads can cause the Query service to crash with OOM errors due to thread contention. Managed Fusion 5.9.14 resolves this issue. If you’re impacted and not yet on this version, contact Lucidworks Support for mitigation options.
