Release Notes
!!Important if you are using "Content-Security-Policy" meta tag!!
Starting from version 2.5.6 on we are using web workers to handle timers. This will allow for timers to run properly even when browser tab is inactive or browser running in background mode. In order to make it work in the correct way, you need to add worker-src directive to your content security policy. You also need to add child-src directive as a fallback to browsers not supporting worker-src directive as follows:
<meta http-equiv="Content-Security-Policy" content="default-src 'none'; --- other rules ----- child-src 'self' blob:; worker-src 'self' blob:;">
