Having said that, I'm going to share some posts provided on Slack channel, Wilders forum and GitHub: reference n. If someone would like to provide contributing guidelines through a pull request, see: Oh and before I forget - thank you very much for actively maintaining and improving Sandboxie! 😉 I would really like to have an option to support/pay for Sandboxie Plus that is not time restricted in any case (like in Large, but without the limitation to the major release). It could also mean, that even the Small option could remain functional for an indefinite amount of time. The wording 'at least x years' and 'until a major release' are very vague and could mean, that a purchased supporter certificate could start expiring at any time.

has the similar issue with Medium, but delayed until a new major release.

all features available during the validity period remain enabled for newer builds 👍 until a new major release 👎.

valid for at least two years (could be the same as small?).

This is somewhat near to a perpetual license, but it does not work well with software that might need to be kept up to date to function. This could also render Sandboxie useless, if there are breaking changes in some Windows updates.

after expiration, the license is invalid for newer builds.

after expiration, the license is invalid.

valid for at least one year (what does that even mean?).

This is what I understood from the currently available options: However, the 'supporter certificates' basically sound like a commercial subscription model instead of a donation initiative. I understand, that software development takes time and effort and therefore have no problems, paying again for new features of Sandboxie Plus.

I am using Sandboxie since 2011, and also bought the lifetime version from the previous developer. Do I understand it correctly, that there is no 'lifetime' option anymore to unlock all features of Sandboxie Plus?
