Update message

Hi.

I have a Samsung GS3 and it has been showing the next update message:

1.4.3
- Improved compatibibility with some Android devices

- Minor bug fixes

Do you know what does it mean?

Unlocked investigators will be lost if I upgrade the game? I appreciate your help...

It has no effect on unlocked investigators. It just should fix some bugs and so on.
