Product

Observe — Assertion notification chart: Slack assertion notifications now include a chart showing recent assertion results and downstream impact context, with performance improvements for smart-assertion charts.
Observe — Assertion notification redesign: Backported Slack assertion notification redesign with downstream impact summary.
Observe — Push assertion errors to alerts: Surface assertion error details directly in the alert health message UI so on-call engineers see the underlying failure reason without drilling into the assertion.
Observe — Volume assertion decimal thresholds: Volume row-count change assertions now accept decimal values for percentage-based thresholds (absolute row counts remain integer-only).
Observe - UTC timezone always available: Ensure UTC is present in the timezone selector for Assertions
Schema field drawer: Column statistics are now shown in full inline on the About tab of the Schema Field Drawer.
Dataset sidebar Edit/Generate actions: Fixed missing Edit/Generate actions in the dataset sidebar.

AI / Ask DataHub

Slack bot — respond to bot mentions safely: Ask DataHub no longer replays other bots' messages as its own assistant history, and now correctly pivots to the last human in a thread when another bot @-mentions it. Self-mentions are dropped, and a friendly refusal is posted when no human can be attributed.
Slack bot — analytics on bot-triggered traffic: triggered_by_bot, triggering_bot_id, and effective_asker_user_id added to ChatbotInteractionEvent for monitoring and debugging bot-to-bot interactions.
MCP tools — custom ownership types: add_owners / remove_owners MCP tools now accept custom ownership types by name (case-insensitive), matching what users see in the UI, in addition to the built-in OwnershipType enum values.

Platform

Zero-downtime upgrade (ZDU) — prevent overwrites during background sweep: Background aspect schema-version migration sweep no longer overwrites concurrently-updated aspects.
System update — protect env vars during scale-down: Fixed an issue where the system update path could incorrectly patch container environment variables when the consolidated upgrade went through scale-down.
Ingestion source resolution: GraphQL IngestionResolver now resolves the correct originating source.
Dashboard stats: Fixed NullPointerException in DashboardUsageStatsUtils when DashboardUserUsageCounts.usageCount is null (e.g. some Superset usage paths), restoring dashboard usage summaries.

Ingestion / Executor

Snowflake executor — preserve mixed-case identifiers: All identifiers are now quoted in the Snowflake executor source so assertion and observability flows correctly handle mixed-case object names.
Redshift executor: Removed the Redshift connection-closed pre-check that was causing spurious failures.

Security / Dependencies

Spring Boot 4.0.6: Bumped Spring Boot from 4.0.5 to 4.0.6 across all 27 Gradle modules to address CVE-2026-22751 and related advisories.
pycurl: Bumped minimum pycurl version to satisfy CVE minimums.

On-Prem Versions:
- Helm: v1.6.111

Known Issues

Async APIs - DataHub's asynchronous APIs perform only basic schema validation when receiving MCP requests, similar to direct production to MCP Kafka topics. While requests must conform to the MCP schema to be accepted, actual processing happens later in the pipeline. Any processing failures that occur after the initial acceptance are captured in the Failed MCP topic, but these failures are not immediately surfaced to the API caller since they happen asynchronously.

Helm

Recommended acryl-datahub chart version is v1.6.111. Notable values added or surfaced in this chart line:

System update, ZDU, and Elasticsearch

global.datahub.systemUpdate.zdu — preEnable and enable group flags for zero-downtime OpenSearch/Elasticsearch upgrades (bundled stage 10 / stage 20 application flags). When enable is true, scale-down during system update is disabled automatically.
global.elasticsearch.index.upgrade — allowDocCountMismatch, reindexOptimizationEnabled, and optional rollbackDualWriteEnabled for clone backups, doc-count validation, and dual-write rollback during incremental reindex.
global.elasticsearch.buildIndices — tuning for parallel and context-aware reindexing (for example reindexBatchSize, reindexMaxSlices, enableParallelReindex, maxConcurrentNormalReindex, maxConcurrentLargeReindex, cluster heap thresholds, and related retry/throttle settings).

Executor, ingestion, and AI feature flags

global.datahub.executor.ingestions.print_subprocess_logs — emit subprocess logs from executor-managed ingestion (default true in chart defaults).

Primary migration targets for this release remain:

yaml

global.datahub.systemUpdate.consolidatedUpgrade: false → true
global.datahub.monitoring.metricsMode: legacy → jmx_and_actuator

Breaking Changes

V1 UI has been fully removed. The V2 UI is now the only supported interface.
Spring Boot upgraded from 3.5.6 → 4.0.5 (Spring Framework 7.0, Spring Kafka 4.0). This may affect custom plugins or extensions.
Deprecated corpUserInfo.active field is no longer considered for session eligibility. Users relying on this field for login gating should migrate to the supported status mechanisms.
Observe: BigQuery, Databricks, and Redshift assertions that perform live warehouse queries will now time out after 10 minutes to avoid resource hogging. These limits can be adjusted via the DATAHUB_EXECUTOR_BIGQUERY_TIMEOUT, DATAHUB_EXECUTOR_DATABRICKS_TIMEOUT, and DATAHUB_EXECUTOR_REDSHIFT_TIMEOUT environment variables respectively. Snowflake is already bounded by this limit, which is controlled via the DATAHUB_EXECUTOR_SNOWFLAKE_TIMEOUT variable.

Deprecations

Dynamic ownership reassignment for proposals is now an opt-in feature. Proposals continue to work as expected — existing asset owners will still receive and can act on proposals. If your workflow depends on ownership reassignment automatically updating who sees proposals, please enable the option in the Automations section.
(Operations / Helm) Per-workload monitoring configuration is deprecated in favor of cluster-wide settings (global.datahub.monitoring).
(Operations / Helm) Enable global.datahub.systemUpdate.consolidatedUpgrade so upgrades run through the consolidated system-update path and the chart no longer relies on separate one-off setup jobs (e.g. mysql/ES setup jobs) for that flow.
(Automations / Glossary Term AI) The Glossary Term AI automation has been deprecated. This capability will be replaced in an upcoming release.
