As of 2.0, GWT tools are no longer platform specific and they reside in generically-named `gwt-dev.jar`. You are quite likely to have to update build scripts to remove the platform-specific suffix, but that's the extent of it. * The development mode entry point has changed a few times since GWT 1.0. It was originally called `GWTShell`, and in GWT 1.6 a replacement entry point called `HostedMode` was introduced. As of GWT 2.0, to reflect the new "development mode" terminology, the new entry point for development mode is `com.google.gwt.dev.DevMode`. Sorry to keep changing that on ya, but the good news is that the prior entry point still works. But, to really stay current, we recommend you switch to the new `DevMode` entry point. * Also due to the "development mode" terminology change, the name of the ant build target produced by `webAppCreator` has changed from `hosted` to `devmode`. In other words, to start development mode from the command-line, type `ant devmode`. @@ -152,4 +174,3 @@ * Versions of Google Plugin for Eclipse prior to 1.2 will only allow you to add GWT release directories that include a file with a name like `gwt-dev-windows.jar`. You can fool it by sym linking or copying gwt-dev.jar to the appropriate name. * The way arguments are passed to the GWT testing infrastructure has been revamped. There is now a consistent syntax to support arbitrary "run styles", including user-written, with no changes to GWT itself. For example, `-selenium FF3` has become `-runStyle selenium:FF3`. This change likely does not affect typical test invocation scripts, but if you do use `-Dgwt.args` to pass arguments to GWTTestCase, be aware that you may need to make some changes. * When using !ClientBundle, be aware that images using alpha transparency do not appear transparent in IE6. The Mail sample application included in the GWT distribution currently suffers from this limitation (that is, the images have opaque backgrounds when viewed on IE6). - * Users of the Google Plugin for Eclipse that are running Google App Engine projects in development mode may see errors like "Unable to find 'myapp.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?". (Note that the app name has been cast to lowercase, that's a symptom.) This is due to an unfortunate interaction between weak references to module definitions and garbage collection kicked off by the App Engine. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
