After upgrading to 17.1.0, monitoring projects whose post-processing plan includes a Database Output step no longer fail validation with
There is no attribute named 'not_applicable_rules' in the catalog item. The not-applicable result columns are now added only when the project has a rule that can produce a not-applicable result, so existing plans validate and run without changes. -
Fixed an issue where exporting a large lineage dataset to CSV could run out of memory and leave a database connection open, which could block other database operations (such as backing up the database in the web application).

Group stewardship assignments on rules, monitoring projects, and terms are now included when exporting and importing metadata. On import, groups are matched to existing groups rather than created, and the import fails if a referenced group is missing. Single-user stewardship is not exported.

Fixed an issue where a review request task could become stuck, showing the View Review Request window with no way to approve or reject the changes.

Faster metadata imports of large content packs, such as the demo data pack, which previously could take up to 20–25 minutes.

Chat with documentation now returns answers and links based on the current 17.1 documentation.
