Qt 5.14.1 in 2025

[QNewbie]

Hello Everyone, due to migration needs I'm required to keep a dual stack of both new and old Qt versions, but the installer goes back as far as 5.15.1.

Is there any way to fetch the required version? or should I fetch it from an active host and just copy plus define the kit in qt creator?

Kind regards,

I think the Qt site has source code archives that go back a long way. If the installers have been taken down, then you may be forced to download source and build binaries from that.

You could also look at revision logs from 5.14.1 to 5.15.1 to see if any of the changes are relevant to your use of Qt. If there aren't many, then you may be able to convince your management to move to 5.15.1 even though long term support for that is ending on May 26, 2025. The Qt company also has an extended security contract for 5.15.1 that they will sell you.
