We introduced a new change in the options object, so we bumped gwty-leaflet to version 0.4-SNAPSHOT straight from 0.3-SNAPSHOT ( 0.3 did not get a release). For the version 0.4, we introduced options builders ( the builder pattern) for guiding the developer to easily see what are the required fields for creating options. Options objects are now immutable native Javascript objects that can only be created using their builders.

The version 0.4 also updated the GWT version from 2.8.0-rc1 to 2.8.0-rc2. More details can be found on the Github page.

The demo project was also updated to accommodate the new version changes.
