Release Notes - What's new in Kyvos 2026.5.x

Additional Features and Enhancements

• Event-Based query performance analysis dashboard
  Introduces an interactive dashboard in Kyvos Visualization to analyze the query performance of Kyvos semantic models based on selected event dates. This dashboard helps users compare query performance before and after significant events, such as system upgrades or configuration changes.

• Git integration enhancements

  • Git Integration for AI Spaces and Workbooks
    Supports pulling and pushing AI Space objects and Workbooks between Git repositories and the Kyvos repository.

  • Git provider enhancements
    Adds support for GitHub and Bitbucket providers in Git connections.

  • Git branch creation from Kyvos

    Supports creating Git branches directly from Kyvos during push operations.

• Download support for managed ZooKeeper logs
  Supports for downloading managed Zookeeper logs through the terminal, similar to Analytical Server log downloads. Users can also configure the INFO or DEBUG log level in the logback.xml file from the ‘Manage Configuration File’ page in Kyvos Manager for troubleshooting and diagnostics.

• Query Engine segmentation enhancements
  Added support for grouping Query Engines into dedicated segments and mapping semantic models to those segments, enabling better workload isolation and more predictable query performance. This release also introduces segment-level memory configuration, providing finer-grained control over resource allocation and optimization at the Query Engine segment level.

• Tier-based command execution for system monitoring
  Added support for tier-based command execution through the ‘Manage Configuration file’ page in Kyvos Manager. Monitoring commands can now be configured in system_config.json, enabling flexible, configuration-driven system monitoring without modifying the monitoring script. This enhancement simplifies diagnostic customization and improves troubleshooting of memory, performance, and operating system-level issues.

• Upgraded Apache Tomcat version
  Kyvos and Kyvos Manager have been upgraded to Apache Tomcat 10.1.55.

Cloud Support Enhancements

• Centralized Kyvos Managed Storage for Logs in AWS and GCP
  Upload logs and dump files from Kyvos Manager to secure Kyvos-managed storage to speed diagnostics, simplify diagnostic data collection, and enable faster access for troubleshooting and root cause analysis (RCA).

• Red Hat Enterprise Linux version upgrade for Azure and GCP
  Upgrades the base RHEL version to 9.7 in Azure and GCP as part of platform and vulnerability remediation enhancements. This update applies to new deployments only and does not impact existing deployments.

• Compute Server Log Archival Enhancements
  Enhanced Compute Server log archival to include heap dump files generated during Out-of-Memory (OOM) exceptions, simplifying troubleshooting and improving root cause analysis.

AWS Enhancements

• Cross-account access support for multiple Athena environments
  Supports cross-account access to multiple Athena environments using AWS IAM Role ARN–based authentication for secure access across AWS accounts.

Azure Enhancements

• New Kubernetes cluster creation for Disaster Recovery
  Supports creating a new Kubernetes (K8S) cluster and recovery resources for Disaster Recovery (DR) using Template Specs in Azure Enterprise Cloud.

• Security enhancements with automated deployments
  Implements vulnerability remediation enhancements, including support for Generation 2 (Gen2) VMs, Trusted Launch security features, and Data Access Authentication Mode for OS and data disks.

Kyvos Manager Enhancements

• Critical notifications for non-interactive activities
  Added support for critical event notifications in the Kyvos Manager notification (bell icon) for non-interactive activities, improving visibility into non-recoverable failures and preventing silent operation failures. Notifications are generated for:

  • Bundled or installed PostgreSQL dump creation failures

  • Snapshot push failures

  • Standby PostgreSQL replication failures

Usability Enhancements

• Enhanced user experience for AI Space
  Enhances AI Space web pages with a more intuitive, streamlined User Interface.

• Collaborative editing for AI Spaces
  Enables concurrent editing for AI Spaces with conflict detection, compare and merge support, and flexible save options.

New Properties

This release comes with the following new property:

• ANALYTICAL_STORE_HDFS_CLIENT_MODE: Specifies the HDFS client mode for the analytical store. Supported values are JNI and NATIVE.

• kyvos.query.sql.simplify.exprFilter: Controls the simplification of expression filters for SQL queries on MDX-based calculations.

API Enhancements

This release comes with the following REST APIs enhancements:

• JSON input support for Kyvos REST APIs
  Supports JSON-based inputs for existing Kyvos REST APIs for the following objects while maintaining backward compatibility with existing XML-based inputs and behavior:

  • Datasets

  • Relationships

  • Semantic Models

  • Folders

Behavior Changes

• Mandatory use of Subject Alternative Name (SAN)-Enabled TLS Certificates
  From Kyvos release 2026.5 onwards, all clouds Enterprise, SaaS, and Marketplace deployments running with JRE 17 must use SAN-enabled TLS certificates. The certificate's Subject Alternative Name (SAN) extension must include the IP addresses and/or hostnames of all Analytical Server, Web Portal, Query Engine, compute master (if applicable) and Kyvos Manager nodes. For more details, click here.
  Note: Certificates that do not contain the required SAN entries are not supported. Hence, users must validate and update their certificates before upgrading to this release.

• Enhanced auto-scaling
  Enhanced auto-scaling to support hybrid scaling schedules, enabling time-based and load-based scaling to be configured across different time windows within the same day. This provides greater flexibility in managing resource allocation based on predictable and dynamic workload patterns.

• Fixed Query Engine Capacity Scaling
  Fixed Query Engine capacity scaling behavior has been enhanced. During time-based scaling operations, queries are held until the scaling activity is complete, ensuring uninterrupted execution. In addition, all Query Engine virtual machines are now upgraded simultaneously, resulting in improved scaling efficiency and faster query execution.

• Username refinement for SSO authentication
  Previously, username refinement was applied to all authentication types, including username/password authentication. Username refinement is now applied only for SSO-based authentication when the property REFINE_USERNAME_FOR_SSO=yes is configured in kyvosclient.properties.

Deprecated items

• Kyvos Dialogs with semantic model
  Kyvos Dialogs no longer supports conversational analytics directly on semantic models. Kyvos Dialogs now supports conversational analytics only through AI Space.
  Existing chat sessions created on semantic models will continue to work with limited backward compatibility support.

• XML-based inputs for Kyvos REST APIs
  XML-based inputs for Kyvos REST APIs are deprecated. JSON-based inputs are now supported for the following objects:

  • Datasets

  • Relationships

  • Semantic Models

  • Folders
