Every update to dojo has attracted countless eyes. In addition to ext, everyone is hopeful about the project with the greatest commercial support and solves bugs to improve efficiency. After all, its license is more popular.

Currently, a similar function is provided for cached layers to support specifying the map zoom level to display cache services, in the past, it was necessary to set in a map service. Now, multiple services (Dynamic layers and cache layers) can also switch between each other.

7. Geometry service update

The labelpoints method of ESRI. Tasks. geometryservices allows you to specify the position point displayed by the label in the polygon.
