Release Notes - What's New in Kyvos 2026.9.x

This release includes the following enhancements to Kyvos Git:

• Automatic Change Detection for Git Operations: Users can now automatically detect changes in entities during push and pull operations. This simplifies synchronization by eliminating the need to manually identify changed entities.

• SSH Key Pair Authentication for Git Providers: SSH key pair authentication is now supported for Bitbucket, GitHub, and GitLab, in addition to the existing supported Git providers.

This release supports creating semantic models from Apache Ossie YAML files using Quick Data Modeling. Users can import a supported YAML file, configure the required connection and folder details, and enable AI Context during semantic model creation to add AI-specific business context to the semantic model.

This release enhances the Kyvos Web Portal navigation by organizing related use cases into logical groups and adding a use case search. Users can easily navigate through related use cases, browse them within their respective groups, and quickly find the required use case.

This release enhances Column-Level Security with support for AND/OR conditions for column restrictions and introduces Intersection Mode for resolving restrictions across user groups. To configure the column restriction resolution strategy, specify the required value for the CLS_RESOLUTION_STRATEGY property.

• Intersection (OR): Users get the intersection of restrictions from all groups, providing the most permissive access based on group memberships.

• Union (AND): Users get the union of all restrictions from all groups, providing the most restrictive access.

Enhanced Semantic Model Access Control

This release enhances validation of semantic model-level privileges when models are accessed through shared AI Spaces, ensuring that users can access and query only the models for which they have the required permissions. The enhanced validation applies across Kyvos Dialogs, conversational interactions, MCP, Microsoft Teams, and Slack.

Kyvos and Kyvos Manager have been upgraded to Apache Tomcat 10.1.60.

This release includes the following AWS, Azure, and GCP enhancements:

• Multiple Data Export Directories for Data Source Connections
  This release supports configuring multiple data export directories within a semantic model, allowing each data source connection to use its own configured export location. This is useful when datasets use different data source connections, such as Amazon Athena, Snowflake, and BigQuery, with different customer storage locations for data export.

• Vertex AI Service Account Credentials in Secret Manager
  This release supports providing the Google Service Account JSON directly when configuring a Vertex AI connection and securely storing the credential in Secret Manager in encrypted form, eliminating the need to place the JSON file on the server.

• Non-SSH Kyvos Cluster Deployment Support for AWS and GCP
  With this release, users can deploy and manage the lifecycle of Kyvos clusters without requiring SSH access to cluster nodes for AWS and GCP.

• General Purpose SSD (gp3) Disk Type Support for AWS Enterprise Deployments
  This release adds General Purpose SSD (gp3) as a disk type option for Kyvos deployments.
  Note: All new Amazon RDS instances created through automated deployments use gp3 disk type by default.

• Query Engine Segmentation and Planner for Azure
  This release supports Query Engine Segmentation for Azure, enabling independent management of Query Engines by workload or use case. Each segment can use a separate Azure Virtual Machine Scale Set (VMSS), with semantic models mapped to the appropriate segment to isolate workloads and their Query Engine resources. The new Planner capability enables segment-level elasticity through independent scaling schedules, capacity settings, and scaling behavior, allowing resources to scale based on workload requirements.

• BigQuery Service Account Private Key JSON Stored in Secret Manager
  This release supports providing the Google Service Account private key JSON directly while configuring a BigQuery warehouse connection. The private key is securely stored in encrypted form in Secret Manager.

• Support for Dedicated ZooKeeper Nodes
  Kyvos now supports deploying ZooKeeper on dedicated nodes, independent of the Kyvos Manager, Web Server, and BI Server nodes. For post-deployment and post-upgrade configurations, users can now select the nodes on which ZooKeeper can be deployed.

• Case-Insensitive Member Resolution in CUBEMEMBER Function
  This release enhances the CUBEMEMBER function to resolve member names consistently and case-insensitively, whether the complete hierarchy path or only the leaf-level member is specified. To enable this capability, add the ‘kyvos.query.casesensitive.memberresolution’ property under ‘Advanced Properties’ on the ‘Refine’ tab and set it to ‘Disable.’

  Note: The default value is Enable, which preserves the existing case-sensitive member resolution behavior.

• Non-Visual Totals Support in Excel
  This release adds support for Non-Visual Totals in Excel, enabling totals to be calculated independently of the filters applied to the visual.

• Task Count for Semantic Model Jobs: This release adds support for displaying the total number of tasks launched for each job in the job details, enabling users to review task counts after the job is completed and analyze resource utilization across semantic model process to support efficient resource planning and improve overall business resource analysis.

This release comes with the following new property:

• CLS_RESOLUTION_STRATEGY (olapengine.properties): Defines the column-level security resolution strategy for restrictions across multiple groups, where UNION combines restrictions from all groups and INTERSECTION applies only the restrictions common to all groups.

• ENABLE_KYVOSPGBI_SERVER (globals.properties): Enables the Kyvos PostgreSQL Analytical Server in the Kyvos web application.

This release comes with the following REST API enhancements:

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

  • Export Semantic Model Field Lineage

  • Import Semantic Model Field Lineage

  • Export Worksheet Data

  • Export Semantic Model Writeback

  • Manage Notification Subscriptions

• New APIs
  This release includes the following new APIs:

  • Business Relationship APIs: Supports Business Relationship APIs for managing Business Relationships. These APIs enable users to create, copy, validate, update, move, and delete Business Relationships, as well as retrieve related information such as source models and folders.

  • Git Pull API: Supports a Git Pull API for Git connections that pulls entities and files from the configured Git repository into Kyvos in a single request.

• BigQuery JAR Upload Functionality Discontinued
  Kyvos Manager no longer supports uploading BigQuery JAR files, as they were only required for new Spark-based GCP deployments, which are now discontinued.

  The following properties have been removed in this release and are no longer available or supported:

  • No-Spark Semantic Model Properties

    • BLOCK_CACHE_PERCENTAGE
