Changelog (evoviu)

Version 8.5.0

Release date: 2026-08-05

Summary

• The application now supports the use of external SD cards for flexible storage and management of images and process data.

• Users can make MQTT communication more stable and flexible through configurable quality levels (QoS) and advanced subscription options.

• A new visual fill-level indicator and detailed storage overviews in the settings enable proactive monitoring of all storage media.

Version 8.4.2

Release date: 2026-07-01

Summary

• Improved error handling in the Image Source: An issue was fixed where backend errors (e.g., caused by invalid camera settings such as excessively long exposure times or resolutions) were not being reported consistently to the user interface. Error messages are now reliably shown as pop-ups, and the affected process is correctly stopped to avoid follow-up errors (such as the "409 Conflict") on restart.
