@hashemi: Many web software modifications and extra components lose compatibility with major releases, due to the large amount of changes that take place, such as the removal of a function, or a change in the way something works that makes a certain modification cease to work properly. As such, it is the responsibility of the developer to ensure they keep their offerings up-to-date and compatible with the latest release of the supported software. Even Windows and MacOS lose compatibility with certain see more applications over time, as there are changes to system components and API that leave certain functions, or even entire applications, unable to function. While such companies as Microsoft and Apple try to retain as much backwards-compatibility as possible, even they admit that by doing so, they hinder the true potential of their offerings, because they must support legacy applications for companies which refuse to adapt.

This is a natural part of software development, and must be done to ensure progress.
