Patch 12
ONE
ONE Web Application, Data Processing Module, Data Processing Engine, Lineage Scanning Service, Metadata Extraction Service, MDE Database Migration
- Lineage
-
-
The Denodo lineage scanner now supports SSL/TLS connections. You can upload truststore and keystore files directly when configuring a Denodo scan plan.
-
Databricks lineage scans scoped to specific catalogs now correctly limit file and path lineage to the catalog’s storage locations, preventing scans from collecting large volumes of unrelated external storage lineage.
-
Assets coming from Azure Blob File System are correctly recognized during metadata extraction.
-
Upgraded third-party dependencies in Lineage Scanning Service and Data Processing Engine for enhanced security and stability.
-
- Authentication & security
-
-
In self-managed deployments, encryption checks no longer return an
INDETERMINATEstate due to a missing key alias property.
-
Patch 11
ONE
ONE Web Application, Metadata Management Module, Data Processing Module, Data Processing Engine
- Monitoring projects
-
-
Monitoring projects on catalog items from a local file system with Spark post-processing plans no longer incorrectly fail model validation.
-
- ONE Data
-
-
Date values entered or pasted into ONE Data are now interpreted consistently across supported date formats.
-
- Usability & display
-
-
The Stewardship widget now reliably shows all governance roles linked to a business term, instead of loading only some after a manual refresh.
-
- Performance and stability
-
-
Pushdown profiling of wide tables and views is now more resilient, avoiding intermittent failures and excessive connection-pool log noise.
-
Fixed an issue where the ONE Web Application could fail to start and remain in a reduced-availability mode due to an error in the job recovery process.
-
Monitoring metrics no longer display as
NaNafter switching an environment to maintenance mode and back.
-
- Authentication & security
-
-
Fixed an issue where Keycloak could fail to start after being upgraded from version 25 to 26 when realms were re-initialized.
-
Upgraded third-party dependencies in DPE and DPM for enhanced security and stability.
-
- Observability
-
-
Database backup and restore operations now log their start time, making it easier to determine the exact window during which database connectivity was affected.
-
Added advanced encryption metrics to DPM, showing whether advanced encryption is enabled and how many connected DPEs have invalid encryption settings.
-
MDM
-
Improved logging and metrics for MDM task execution and the transaction collector, making it easier to diagnose long-running or conflicting transactions.
-
Fixed an issue where MDM data statistics could drift during highly parallel commits (
commitParallelgreater than 1), causing active and inactive record counts to be incorrectly counted. -
Added an option to recompute data statistics, allowing existing statistic drift to be corrected without running manual SQL against the database.
-
Using pagination on the MDM Scheduler screen in the MDM Web App Admin Console no longer causes subsequent actions such as Enable, Disable, Run, and Refresh to fail with an HTTP 500 error.
-
Opening the SQL expression help from the Advanced filter in the MDM Web App no longer returns an HTTP 401 error for already-authenticated users.
Patch 10
ONE
ONE Web Application, Metadata Management Module, Data Quality Firewall Service
-
Fixed an issue where rules returning
NOT_APPLICABLEduring rule testing were incorrectly reported asCORRECTwhen run inside a monitoring project after upgrading to 16.3.1. -
Fixed an issue where rule testing was only available to users with Editing access level on rules instead of View metadata after upgrading to 16.3.1.
-
The Lineage Configuration screen now shows the health status of edge instances, along with information about when the instance was last polled.
-
Fixed an issue where external event persistence could stop after a database connection error, stopping notifications in ONE until restart.

Patch 8
ONE
ONE Web Application, Metadata Management Module, Data Processing Module, Data Processing Engine, Task Service, Workflow Service, Data Quality Firewall Service, Metadata Extraction Service, MDE Database Migration, Lineage Scanning Service, Audit Module, AI Evolution
- Authentication & security
-
-
Upgraded Keycloak components and third-party dependencies for enhanced security.
-
Upgraded authentication libraries in ONE Web Application, Workflow Service, and Task Service for improved security.
-
Upgraded third-party dependencies in the following modules for enhanced security and stability: ONE Web Application, Data Processing Engine, Audit Module, Metadata Extraction Service, Lineage Scanning Service.
-
- Catalog & data processing
-
-
Reduced memory pressure in Data Processing Engine when processing large XML and JSON documents downloaded from object storage, preventing potential out-of-memory failures.
-
DQ evaluation on Spark no longer fails with
ArrayIndexOutOfBoundsExceptionduring sample merging.
-
- ONE AI
-
-
ONE AI rule indexing no longer fails entirely when a single rule cannot be processed. Previously, an unsupported variable type (such as FLOAT) on a single rule caused the entire indexing job to fail with a
Detection data type of expression … failed.error, preventing all rule embeddings from being updated.
-
- Lineage
-
-
Improved SSIS lineage scanner performance and correctness: component queries are now filtered by
pipeline_id, and source components are correctly scoped to the requested pipeline.
-
- Business glossary
-
-
Mandatory term properties of type
referenced object arrayandreferenced objectwith thevalueList:propertytrait now show the required field indicator (red asterisk) on term editing forms. Previously, the indicator was missing and the requirement was only surfaced as a validation error on publish.
-
MDM
-
Upgraded authentication libraries in MDM for improved security.
-
MDM cleansing tasks no longer hang indefinitely under rare race conditions during plan reloads, which previously left tasks stuck and required a restart to recover.
-
MDM streaming event handler now publishes updates for every record change. Previously, only the first version of a record was written to the streaming output.
-
Restored the default value of
nme.vldb.commitSizeto10000, re-enabling intermediate commits during the MDM committing phase. Previously, the default of-1ran the entire phase as a single transaction.

-
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
adminrole and a custom governance role assigned in Keycloak, instead of failing with aMismatchedInputExceptionerror. -
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.propertiesfiles are now loaded correctly on the first MDM Server startup in Ataccama Cloud environments.
