TrueConf Server 5.5.2: Security updates, upgraded interface, and new capabilities

Meet TrueConf Server 5.5.2, the new version of our messaging and video conferencing platform for Windows and Linux which brings security updates for November 2025. Besides, in this update, we’ve added support for Debian 13, a dark theme for some scenarios, and made the real-time conference management tool more user-friendly.
Note: when upgrading from TrueConf Server 5.5+, no registration is required. In other cases, please read our guide.
New UI of the real-time meeting management
We’ve updated the interface of the real-time meeting management — all the necessary items have been moved from the context menu to the home screen. In addition, we have added the ability to enable or disable the conference transcription if you have integration with TrueConf AI Server configured.
How to go to real-time conference management? If you are a moderator, click the
button on the conference control panel and select the appropriate context menu item.
Dark theme in the scheduler and personal area
The conference scheduling section in TrueConf client apps has also received a visual update. If a dark theme is set in the application, the scheduler will be displayed in the same color scheme. In addition, the user personal area, which you can log in from the TrueConf Server guest page, has also received support for a dark theme — it is enabled automatically if the appropriate color scheme is set in the user’s browser.
File transfer restrictions
TrueConf Server 5.5.2 brings the ability to limit the maximum size of files sent by users, as well as select the file extensions allowed for sending.
How to enable? Go to the File storage section of the TrueConf Server control panel and set the necessary restrictions
