# Toolbox App 3.7: JVM Memory Optimizations and Update Improvements JetBrains Toolbox App optimizes JVM memory usage and makes update processes more reliable. - **Source:** [The JetBrains Blog](https://brifing.si/source/782eebd1-7be8-49cc-b27c-e552516691b2) - **Published:** 2026-08-18 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/53c58c83-5338-46be-84da-d4e1c117d4a7 ## Key Features of Toolbox App 3.7 JetBrains Toolbox App 3.7 enables JVM memory optimization by default, improving memory efficiency across all operating systems. Update processes have been made more reliable, and session expiration recovery has been enhanced. Compatibility issues with Windows Smart App Control have also been resolved. ## Update Requirement for Windows Users If you're using an older version of the Toolbox App (3.4 or earlier) on Windows, you need to update to version 3.7 or later to continue signing in to your JetBrains account. Older versions may fail to store or refresh credentials used by some JetBrains services. ## IDE Installation and Update Improvements on macOS The Toolbox App has made IDE installation and updates more reliable on macOS 27. During patch updates, the app verifies the code signature of the application bundle and removes files not sealed by the new build. If verification fails, a clean copy is downloaded. ## Details of JVM Memory Optimization JVM memory optimization automatically configures memory management, code-cache behavior, and garbage collection. This optimizes memory usage without requiring any setup from users. For more details, refer to TBX-18852. ## Compatibility with Windows Smart App Control The Toolbox App now launches correctly when Windows Smart App Control is enabled. This ensures smooth operation on systems with high-security settings. For details, refer to TBX-18777. ## Resolving Session Expiration Issues If you've encountered 'session expired' notifications, try updating to Toolbox App 3.7. An issue caused by temporary network interruptions has been addressed. If the problem persists, users are encouraged to provide feedback. ## Importance of User Feedback The JetBrains Toolbox App team is eager to hear users' thoughts on version 3.7. Feedback helps improve the app further. Users can share their experiences in the comments to contribute. ## The Evolution and Significance of Toolbox App Toolbox App 3.7 enhances the user experience with JVM memory optimization and improved update processes. This update ensures smoother operation of IDEs for developers and more efficient use of system resources. ## Sources covering this story - https://blog.jetbrains.com/toolbox-app/2026/08/toolbox-app-3-7-jvm-memory-optimizations-and-update-improvements/ — --- _Summary written by Brifing from the original reporting.
