Dash v3.0.2

Changed

• #3113 Adjusted background polling requests to strip the data from the request, this allows for context to flow as normal. This addresses issue #3111
• #3248 Changes to rendering logic:
  • if it is first time rendering, render from the parent props
  • listens only to updates for that single component, no children listening to parents
  • if parents change a prop with components as props, only the prop changed re-renders, this is then forced on all children regardless of whether or not the props changed

Fixed

• #3251. Prevented default styles from overriding className_* props in dcc.Upload component.

Added

• #3248 added new dashRenderType to determine why the component layout was changed (internal, callback, parent, clientsideApi):
  • this can be utilized to keep from rendering components by the component having dashRenderType defined as a prop, and the dashRenderType = true must be set on the component, eg (Div.dashRenderType = true)
