New features

Query History and Bookmark Manager | Now under one roof

In case you’ve overlooked these powerful features, it’s the best time to dust them off. Now you can view your bookmarked queries and search through your query history in one place.

The History tab of Query Manager

We’ve also included a last “Executed date and time" column in the History tab and a “Last modified date and time" column in the Bookmarks tab to help you identify your queries more easily.

Find the History and Bookmarks tabs in the Query Manager, which you can access in SQL Query, IntelliShell, Aggregation Editor, and the Collection Tab by either clicking on the ellipsis or star icons at the top-right corner.

App-wide | Show elapsed time for running queries

Are your queries taking longer than expected? You can now see how much time has elapsed for any given query at the bottom-right corner of the SQL Query, Aggregation Editor, Map-Reduce, IntelliShell and the Collection Tabs.

Elapsed time indicator for queries

Connection Manager | A better way of displaying databases

We’ve added two additional checkbox options in the Connection Manager to help you control which databases to display in the Connection Tree.

(NEW) Always show the authentication database of the user account – Checking this box will always show the authentication database in the Connection Tree.

(NEW) Always show all databases defined in roles of the user – Checking this box will additionally always show any other databases that your user privileges allow, e.g. databases that contain collections your user privileges grant you access to.

Manually list additional visible databases by their names – In most cases, Studio 3T will automatically list the databases that should be visible to non-admin users. In some cases when this information isn’t available, you can check the box and manually specify them here.
