let me fix that for you.
https://www.stardock.com/products/fences/history
v3 was released in 2016.
v4 came out in 2021 and has only been updated 4 times in total, 5 if you include the newest update that adds in an ad for v5.
you absolutely will not get your moneys worth if you go with the subscription.
v5 doesn't even add any new features on top of v4 as far as i can see. the "new" chameleon feature that is advertised is already possible with v4.
i bought fences back in 2010 for 10, bought v2 in 2014 for 8.5, upgraded to v3 in 2016 for 5, and then upgraded to v4 for 8 in 2023. 31.50 in total and now they want 30 for me to go from v4 to v5. Stardock has lost a longtime customer with this BS.
