This is a rather big release and it brings quite a lot of improvements and bug fixes, mainly for the Server. Most importantly, we have fixed a bug affecting work with Google Ads API: previously, running several queries simultaneously might cause out-of-memory errors. Now you can safely run multiple Google Ads jobs without encountering errors. Another important bug fix improves REST API queries performance: we have resolved a bug causing the JsonStreamer.write method to not use a buffer and send the data byte by byte to the RESTEasy output stream.
A whole bunch of fixes concerns Column Level Data Lineage: the path is now highlighted for a view if the query contains aggregation or DISTINCT or arithmetic operation or concatenation; the SYSADMIN.getDataLineageWithRelationsOnly procedure will not display temporary tables in the plan and will not fail with an assertion error anymore and will return the correct information for materialized views with enabled optimization; and WITH queries (also known as CTEs) will return correct results on generation of data lineage.
As for the Studio, we have fixed three bugs, thus improving performance and security. The job tab will no longer freeze if there is a job with a comma in the description; if a Dependency graph or an Impact analysis tab is open for a non-existent object, no error message will be shown upon reconnecting (the tab will now display a relevant message, 'The %procedure|table|view|schema' does not exist;); and last but not least, virtual schemas will not be shown in the Data Sources section if permissions are set to objects in those schemas but not the schemas themselves.
And finally, an improvement and a bug fix for the connectors: for Amazon Selling Partner, the Orders procedures will now save data into subordinate tables, and for Google Ads API, reports with the bidding_strategy and accessible_bidding_strategy parameters will yield correct results.
