Very nice, and thanks again for this nice library!

[Slamdunk]

The PR is ok, but I'd like to remember that this will not prevent anyone to install ddeboer/imap:1.12.1 and run into #485 again.

Of course the user will eventually see the usage of an outdated version and question why, but still I feel @matthiasnoback's "hours of debugging time" will hit again many other users.

[ddeboer]

That’s a good point @Slamdunk. Except for retagging previous versions (bad practice), or perhaps adding a section to the readme (which developers may or may not read), I don’t see a way to completely prevent that. Do you have any ideas?

[Slamdunk]

Already happened in other repos, no way to do it well, but no need to bother IMHO, composer notifies you are on an outdated minor, and we require to specify PHP version in order to open an issue, so we can address eventual new related issues quickly.
