Good question. kk is right - with a change in *major* version (such as 
2.4 to 3.5, 3.5 to 3.6) the compiled extensions will be incompatible, 
and will need to be recompiled. This can take a while, as extension 
authors frequently have other things to do besides maintain their 
extensions.

As you have found out, though, when only the *minor* version changes you 
can just frop the new version in over the old and all your installed 
extensions and packages continue to work just fine.
