Patch 7

May 11, 2026 ONE DQ&C ONE MDM ONE RDM ONE Runtime Server

ONE

ONE Web Application, Metadata Management Module, Data Processing Module, Data Processing Engine, Metadata Extraction Service, Lineage Scanning Service, Task Service

Authentication & security

  • Upgraded third-party dependencies in Data Processing Engine, Task and Workflow services for enhanced security and stability.

Ataccama Cloud environments

  • Metadata Management Module now becomes available reliably after upgrade in Ataccama Cloud environments, even when MinIO is briefly not ready to accept writes.

  • Improved MinIO stability and security in Ataccama Cloud environments.

Lineage

  • Power BI lineage scans no longer stall between workspaces when scanning connections with many workspaces.

  • Oracle lineage scanner now supports databases using non-default character sets such as Central European or Cyrillic. Previously, scans failed with ORA-17056: Non-supported character set.

  • Scan plans for dbt connections now display the dbt logo instead of the SAP logo.

  • Improved database logging in Metadata Extraction Service for faster troubleshooting.

Usability & display

  • Metadata Management Module now clearly signals when it’s in maintenance mode. Previously, non-admin users would receive a misleading authentication error.

  • The Stewardship widget on glossary term pages now reliably loads all governance roles on first page load. Previously, the widget would show only basic stewardship information in certain cases until the page was refreshed.

  • Tasks Overview screen now loads correctly for users who have both the admin role and a custom governance role assigned in Keycloak, instead of failing with a MismatchedInputException error.

  • Catalog items in monitoring projects no longer intermittently display the record count of a previously viewed catalog item when navigating between them in Configuration & Results.

MDM

  • The Last run column on the Load Operations tab in the MDM Web App Admin Center now correctly updates when load operations are executed via the Run MDM Multi Load workflow task. Average duration is skipped as load durations within a multi-load are not directly comparable.

  • MDM runtime.properties files are now loaded correctly on the first MDM Server startup in Ataccama Cloud environments.

RDM

  • Editing rows in Views with Edit Rows Filters configured no longer fails for users without full permissions.

ONE

ONE Web Application, Metadata Management Module, Data Processing Module, Lineage Scanning Service, AI Evolution

  • Transformation plans with an Add attributes step no longer fail validation with errors like The type of the attribute 'X' must be LONG but is INTEGER. The validator now accepts implicit type widening (INTEGER→LONG, INTEGER→FLOAT, LONG→FLOAT, DATE→DATETIME) between expression types and declared attribute types.

  • Fixed an issue where jobs could intermittently get stuck in the DPM queue and never be submitted to DPE, with the Detected old submitting job message appearing in the DPM Admin Console.

  • Catalog items in monitoring projects no longer intermittently display the record count of a previously viewed catalog item when navigating between them in Configuration & Results.

  • Power BI lineage scanner no longer fails on Mashup expressions with missing or null values.

  • Restructured the AI Evolution service to streamline maintenance of AI features.

Patch 5

April 21, 2026 ONE DQ&C ONE MDM (Server only) ONE Runtime Server

ONE

ONE Web Application, Metadata Management Module, Data Stories, Audit

  • Rich text values written to business terms via the ONE Metadata Writer step in ONE Desktop now display correctly in the ONE web application.

  • Credential types, catalog item types, and schedule types appear with correct display names, for example, Username and password for PostgreSQL credentials, instead of Username password credential.

  • Upgrades no longer fail with an index error on the attribute_qx backup table in environments previously upgraded from older versions of Ataccama ONE (for example, 14).

  • Upgraded third-party dependencies in ONE Web Application, Metadata Management Module, Audit Module, and Data Stories for enhanced security and stability.

MDM

  • Kafka stream consumers no longer fail with Kafka stream source is not producing values of type string when receiving null (tombstone) messages.

  • Upgraded third-party dependencies in MDM Server for enhanced security and stability.

ONE Runtime Server

  • Upgraded third-party dependencies in ONE Runtime Server for enhanced security and stability.

ONE

ONE Web Application, Metadata Management Module, Data Processing Engine

Catalog & search

  • Filtering by keyword values now works correctly when the search text contains uppercase words such as AND, OR, or NOT.

  • Searching by indexed properties that belong to a parent entity type works as expected in search configurations.

Usability & display

  • Faster loading of user and role selection dropdowns in project notifications, observability settings, and DQ firewall configuration, especially in environments with many users.

  • Date filter inputs no longer change the entered date to an incorrect value in Ataccama Cloud Portal.

Data processing

  • Profiling jobs with regex-based detection rules no longer get stuck on columns containing large text values. The maximum input length for regex evaluation can be limited using the MAX_REGEX_INPUT_LENGTH DPE property.

Performance and stability

  • Improved system validation performance and resource management.

  • System validations correctly respect the configured allowed window constraint.

Security

  • Upgraded third-party dependencies in DPE for enhanced security.

MDM

  • MDM server no longer runs out of memory when the streaming event handler encounters parallel write conflicts during large batch operations.

  • Upgraded third-party dependencies in MDM server for enhanced security.

ONE Desktop

  • ONE Metadata Writer step now supports longer SQL queries.

Patch 3

Infrastructure-only release. No user-facing changes.

Patch 2

April 10, 2026 ONE DQ&C ONE RDM

ONE

Data Processing Engine, Audit Module

  • New Ataccama Cloud environments now correctly use a 90-day audit database retention default. Previously, new environments were initialized with 365-day retention.

  • Upgraded third-party dependencies in DPE and JDBC drivers for enhanced security.

RDM

  • RDM Server now connects to the database as expected in Ataccama Cloud environments using shared or dedicated Aurora databases.

ONE

ONE Web Application, Metadata Management Module, AI Evolution, Data Stories

Lineage

  • When selecting an attribute on the home datastore, the diagram now filters to show only datastores connected to that attribute. This option is auto-enabled for large diagrams; you can manage it in the view settings.

  • Faster attribute display and transformation context loading on large lineage diagrams.

Data Stories

  • Data Stories visualizations now work correctly with ONE Data catalog items whose underlying tables are re-created during postprocessing exports.

ONE AI

  • AI rule indexing no longer fails for rules without input variables.

Infrastructure

  • In Ataccama Cloud environments, JAVA_OPTS are correctly configured for DPE when custom trust certificates are enabled.
