Hi! That email was only sent out to people who purchased Pixel8r 1.0 (which had a free v1.5 update) but not Pixel8r 2.0.
Pixel8r 2.0 (and its free v2.5 update) was always a separate purchase on Gumroad. I have just moved stores.
Anyone who previously purchased 2.0 on Gumroad is still able to download the latest updates.
If you *did* purchase 2.0 and still got that email, you probably did it without an account or via a different email address. If that is the case, check your emails for your receipt and you'll have a link to access the download page, where you can get 2.5.
