I just noticed that with scheduler 7.2.3, the month view has lost the color of the current date.
Week with background for today:

Month without today highlighted:
An extra item is there:

But I was using these CSS classes before:
.dhx_scale_holder_now, .dhx_now .dhx_month_head, .dhx_now .dhx_month_body {}

Hello @niccokunzmann,
Yes, it looks like a bug on our end, thank you for noticing it. I already sent it to the dev team, and they will work on fix.
You can avoid this issue by manually add required class to month cell, like follows:
scheduler.templates.month_date_class = function(date){
if(date.setHours(0, 0, 0, 0) == new Date().setHours(0, 0, 0, 0))
return "dhx_now";
};
