2025.4
This release introduces the ability to raise support tickets directly from Data Hub, a preview of custom query design in Zap Live, and several modeling enhancements.
Data Hub enhancements
Raise a bug from within Data Hub
We want to make it as easy as possible for you to get the help you need. If you think you've found a bug, or if something isn't working the way you expect, you can now raise a support ticket directly within Data Hub. This form allows you to describe your issue, and will automatically include technical information about your Data Hub environment, giving us the necessary context to assist you effectively.
Zap Live enhancements
Custom queries preview
A preview release of the upcoming custom queries feature is now available in Zap Live. This allows you to design custom queries from scratch directly within the Zap Live task pane. See Designing a custom query for more information.
Modeling enhancements
Model size improvements
Where possible, we'll now show you a breakdown of how your models are using space in the data warehouse.
Auto materialization mode
By default, new pipelines will be set to Auto for their Create pipeline as setting, which will automatically choose View or Table based on the pipeline design. In most cases, this should provide the best performance when processing the pipeline.
Processing no longer blocked by profiling and preview queries
Model processing could previously be blocked by long-running queries that were profiling or previewing the model. This is no longer the case, and these queries will be canceled when processing starts.
Delta processing support for Tabular models
Pipelines created as Delta tables are now fully supported in Tabular models, with similar performance improvements as dimensional models.
Deprecated functionality
All Tableau integration has been deprecated and will be removed in 2025.6.
