Django 3 book - is it still worth buying

Hey, guys! My first post here.

I got into learning Django recently, and it happened that I got some Gift Vouchers for a local book store. There I found this Django 3 book which looks very interesting to me:
When I checked, latest Django version is 5, so my question is, if I take Django 3 book, did I waste my money (voucher)? Can it be used as a basis to Learn Django 4 and 5 (for as much as I can see, Django 4 added async stuff out of major changes etc).

Thanks in advance!
