Version is the latest & only available to download, so 10.52.2.
PS: I feel exactly the same as you, Oren.
I used to have a premium account too, then prices went up like crazy (12€/month for a note app, for personal use, sounds crazy to me, especially when compared to other monthly subscriptions) and I went back to the free version, as I never used the premium features (more data, more devices... I have no use of it...).
If it were for <4€, why not, but damn, 12€/month, that's more than spicy for what it is...
