Tabs: Fixed duplication of templates for each page in Tab Widget (this lead to a perceived freeze, due to strong performance degredation and exponential behavior. To fix this, briefly load a layout without the offending tab widget and reset the user settings) Aligned variable entries to the left Fixed color not updating in y-t Diagram Fixed variable select not working as expected, when using tags or filters in prior nightly Implemented reset of user settings Fixed CAN interfaces not opening Decreased default brightness from 56% to 50% Disabled buzzer sounds Fixed BMP files not loading Various improvements regarding backlight regulation Lists: Sort and filter improvements Tag menu has been added to variable select Close button does not appear on sub-keyboards anymore Cycling and opening of layouts according to language settings Virtual keyboard now has close button Variable Select now has search function Nightmode has been added ActionMacros, CanSendMsg and MeasEvent now don't evaluate to true on condition errors anymore This fixes spurious actions, such as windows opening, on logger connection |

| 2025/11/10 beta | 10.11.25 | Initial draft |
This is always the new version, with the newest features. It is not thoroughly tested and thus not deemed production-ready.
Unless you really need a specific feature or feel like experimenting, it's suggested to wait,
until it appears in the table above. Nightly versions will be removed once a new one becomes available.
These updates can be rolled back by installing an older version.
