Hi! I'm a student, a user of Sibelius and would like to crossgrade from Sib to Dorico. I've tried a month of Dorico and it really is so convenient!! I saw on Dorico website that the crossgrade under education is 159.99 bucks, and wonder if any discounts later this year would make it even more affordable? And when will Dorico 4 be released? (I just saw this promotion page and regretted that I didn't see it earlier!!) Thank you!
