Release notes

8th September 2019: Important beta update release, where an issue wint Windows 10 build 17763 is fixed hopefully, eyeblink did not get the signal from operating system that the screen is of/on, so I added listing to other events like user away, this hould help to solve the issue. The other important step is fixing the battery saver and screen brightness adjustments while it is on. It was causing trouble. Hopefully fixed. There is now a radio button for simple reminder so now it should be clear which reminder works how and which one is enabled. Several bugs fixed.

3rd August 2019: Several bugs caused crashes fixed. Crash dumps (only app states during the crash data) are sending automatically to servers to be able to fix issues further. Automatic brightness based on the room light is labeled as experimental, it still does not work properly when the background changes. Few crashes are still noticed, for now my intuition tells me that it is a bug in Qt and the other crash causes OpenCV. I added few other logs, so maybe in future I will find out what is the cause to prevent it.

1st May 2019: major update, many bugs fixed, hw brightness and color temperature features added, crash handler added, automatic updates added

19th March 2018: Focus lost while working in background fixed.

13th March 2018: PCID added to GUI. A few small bugs fixed.

12th March 2018: OpenGL GUI rendering added, sound reminder fixed. Bug fixed. New installer, therefore you have to uninstall the previous version manually.


5th March 2018: Eyeblink upgraded to 64-bit, new smaller eye detection file, compiler and libraries updated.

31th January 2018: Smart training bug fixed, it was not working sometimes. More precise light measurement enabled, user's face is not included because it is illuminated with the screen which was lowering the precision.

17th January 2018: Break reminder and eye exercises added. New algorithm for room light measurement. If the preference for given room light does not exist, it looks for the most simillar preference. Multiple bugs fixed.
