@siangboon there was a post about 4 years talking about that.
But yes, I wish even PHP had longer life. But still it seems PHP itself stays stable over the years, major changes are gradual. It would be nice if a Laravel version was more like 2 years non LTS, and 4 or 5 years LTS.
I have an older custom framework back form php 5.4 days, and to keep it updated with php has been very easy.
What's funny is other languages like asp.net, there are still major sites on older versions, same for java.
But java does have longer backward compatibility. An old java ee 1.4 app would still run on java ee 6.
It's hard to keep up I know, but if you stay updated, it's easier than getting behind.
I still wait about 2 or 3 months after a new release, so bugs are worked out. They fix stuff pretty fast.
