Is it necessary to upgrade to jQuery 1.4?

Question

I have been using jQuery 1.23 till now and nowadays most of the plugins are being developed for the 1.4 version. So I just want to know is it necessary to upgrade to jQuery 1.4?

I mean all the modules I have right now, will they still work?

Answer 1

No, you don't need to change now as long as things are still working. Eventually, you will need to change because browsers change and, thus, jQuery 1.23 will someday be broken by a browser change. I suggest that you plan on changing soon and work that into your schedule. It's best to try and keep your software current with its dependencies. This will make it easier to adopt new features and reduce the chance that your software will break spectacularly one day and force you to upgrade in an unplanned way.
