How will Google release new versions of Google Web Toolkit? If my app depends on an older version of GWT, will I have to upgrade?

We'll release new versions of GWT on the GWT web site. Barring any unforeseen circumstances, we expect to keep all previous versions of GWT available on the web site as well. As releases become outdated, we'll no longer actively support them on the GWT discussion group, but we'll do our best to keep old releases and documentation around as long as possible.
