clip studio paint just announced that it is releasing a "2.0" version in 2023 which will require a new one time purchase or active subscription. users who do not purchase the new 2023 version will no longer receive feature updates, but will still have access to the "1.x" version forever. users who do not purchase subscriptions will not receive updates to the 2.0 version until 3.0, which will also require a separate "one time" purchase. they are basically phasing out functional one time purchase plans by forcing you to subscribe to continue getting updates, or to continue buying each new major version at whatever interval they are released.
