dash

• #918 Adds wait_for_element_by_id and visit_and_snapshot APIs in browser, adds raw_command option (it also has higher priority than

dash-core-components

Added

• Added support for persistence of user-edited props to value-input components: Checklist, DatePickerRange, DatePickerSingle, Dropdown, Input, RadioItems, RangeSlider, Slider, Tabs, and Textarea. New props are persistence, persistence_type, and persisted_props. Set persistence to a truthy value to enable, the other two modify persistence behavior. See plotly/dash#903 for more details. #646

Fixed

• Fixed Slider and RangeSlider components with tooltip.always_visible #640
• Fixed an infinite loop problem when Graph is wrapped by Loading component #608

dash-renderer

Added

• #903 enables props edited by the user to persist across recreating the component or reloading the page. Components need to define three new props: persistence, persisted_props, and persistence_type as described in the lead comment of src/persistence.js. App developers then enable this behavior by, in the simplest case, setting persistence: true on the component. First use case is table, see dash-table#566

Fixed

• Reduced about 55% of the dash-renderer packages size on PyPI by removing the source maps. To do more advanced debugging, the source maps needs to be generated from source code with npm run build:local and pip install in editable mode, i.e. pip install -e . #910

dash-table

Added

#566

• Support persisting user edits when the component or the page is reloaded. New props are persistence, persistence_type, and persisted_props. Set persistence to a truthy value to enable, the other two modify persistence behavior. See plotly/dash#903 for more details.
  #319
• New 'loading_state' prop that contains information about which prop, if any, is being computed.
• Table no longer allows for editing while the data prop is loading.

Fixed

#578

• Fix #576, editing column names or deleting columns while other columns are hidden causing the hidden columns to be lost.
• Fix an unreported bug that clicking "Cancel" at the column name edit prompt would clear the name, rather than leaving it unchanged as it should.
  #569, #544
• Allow empty strings in all filter_query (e.g filter_query: '{colA} eq ""')
  #567
• Add support for missing border-radius in style_** props
• Fix table's inner vs. outer container styling
  #18
• Fix row selection vertical and horizontal alignment
  #103
• Simplify usage for multi-line cells and ellipsis. The cell's content now inherits the value of
  white-space, overflow and text-overflow from its parent, making it possible to style
  multi-line & ellipsis with style_data and other style props.
  #583
• Fix regression when editing the content of a cell in a scrolled virtualized table

Dash v1.2.0
