Show them somehow it is still supported, update the minor version or something.

In general:

If I come across a 3 year old binary, and no news article about dev activity it looks "dead and unsupported". Also on GitHub, if there is no commit for 1+ year, it looks "dead and unsupported", piling up of Github issues is also a bad sign. Using "dead" binary asks for troubles down roads, when you want to use it in a few months and it stopped working.

Binaries (without external runtime dependencies) generally don't just "stop working" like that unless you change something significant about your system.

Ideally yes, but the world changed. There are a constant stream of updates for your OS, graphic card driver, etc which constantly break things left and right. If it affects a big software, even an outdated version) the user outcry will make sure it get fixed. But you better make sure not to rely on an unsupported 3 year old rather niche software if you plan to upgrade anytime soon.
