GWT 1.7 adds explicit support for Internet Explorer 8, Firefox 3.5, and Safari 4 as well as a few high-priority bug fixes. In all other respects, it is very similar to GWT 1.6. Note, however, that this release is version 1.7 rather than version 1.6.5 to signify a potentially breaking change for libraries that use deferred binding to specialize code based on user agent (see the next section for technical details). If you are upgrading from GWT 1.5, please follow the upgrade path in the GWT 1.6 notes.
The 1.7 release contains a few high-priority bug fixes. It is versioned 1.7 to signify a potentially breaking change.
GWT 1.7.1 includes one bug fix
GWT 1.7 includes a number of critical bug fixes, including
These are the top fixes. For the complete list, see the distribution release notes.
If you are upgrading from GWT 1.5, please see the GWT 1.6 notes for an explicit upgrade path.
This release includes explicit support for IE8, which has some significant
behavioral changes from prior versions of IE. These changes are great enough
that the new value ie8 has been added for the user.agent
deferred binding client property. If you have deferred binding rules (i.e.
<replace-with> or <generate-with>)
or property providers that are sensitive to user.agent, you
may need to update them to account for the ie8 value.
For more information, see the
technical
notes.
