jQuery breaks with old IE versions

jquery-logoThe latest, 1.9 version of jQuery was released today, together with the beta of the 2.0 version. Although both versions share the same API (some features were removed from 2.0 as well as from 1.9), there are huge differences between them:

  • The 1.9 version – just like the previous versions – runs on Internet Explorer 6, 7 and 8, or as they say, on “oldIE”.
  • The 2.0 version will not run on oldIE. This decision results a simpler, faster and smaller library.

According to the Release Notes, both versions will be supported in the future, but I’m afraid that support will not last for ever. Sooner or later the 1.9 version will be deprecated, and new features will be implemented only in the 2.0 version.

Who loses more on this, IE or jQuery? Developers will switch to other libraries, or websites will render IE 6-7-8 obsolete?
