Thanks for the question! The intention is you pay once $5 for the software and are given access to all versions and updates moving forward. I may eventually increase that base price, but of course I will grandfather in and give continued access to updates for those who supported me in this early state. As things are currently configured, a 1 time purchase should give you access to all downloads and versions. I am listing all download versions on the page because sometimes I'll push an update and miss some serious bug. I want to make sure people can easily roll back to a previous stable version.
