* ArcGISCache resolutions get compromised by some JS frameworks. (Closes #3474) * OpenLayers.Layer.HTTPRequest initialize simplification (Closes #3470) * missing requires (Closes #3467) * deleting a vertex does not update feature.modified (Closes #3463) * fixing test failure in some browsers (Closes #3461) * a grid layer may be moved while its grid hasn't been initialized yet (Closes #3458) -- this one is the actual release blocker * Change the callback function of Protocol.Script (JSONP) (Closes #3417) * "build.py -c closure" does not work on Windows systems.
