* Propagate source maps through combine assets step * Use constant development build id * Move combine assets step before uglify step This ensures that uglify will catch these changes. * Move dynamic chunks step before uglify step This ensures that uglify will catch these changes. * Use chunk templates for page and dynamic chunks This is a little more in line with how webpack generates its bootstrap and should have better compatibility with other plugins and source map generation. * Register combined source map with chunks This ensures that a sourcemap is fully generated. * Do not minimize combined map inputs
