   Meet the Islands Theme – The New Default Look for JetBrains IDEs

   JetBrains introduces the Islands theme as the new default UI across all their IDEs starting with version 2025.3. The theme features rounded corners, balanced spacing, improved tab recognition, and clearer separation between working areas. It includes distinct tool window borders for easier resizing and an optional setting for different tool window backgrounds to emphasize the editor. The design was shaped by user feedback and testing, aiming to create a softer, more comfortable environment that supports focus and productivity while aligning with modern design trends from macOS and Windows 11.

   Query Consoles Are Coming Back

   JetBrains is reverting a controversial workflow change in DataGrip 2025.3 that replaced query consoles with query files. The redesign caused issues with global data sources and disrupted user workflows. Version 2025.3.1, releasing this week, will restore the original query console behavior. Users who created query files during the migration can delete them, convert them to consoles, or keep them for a planned improved workflow early next year. The team acknowledges failing their zero-regression standard and commits to more careful, flexible updates going forward.
