Minor Version Changes
* source name is now the key in pipeline state that stores all the source and resource state. previously the source section (which was the name of python module where source was defined) was used. this change will affect the already deployed pipelines that had name of the source different from the name of the module. they will not see the already stored state and may, for example, load some data twice. the only verified source affected by this is zendesk.
