[546](https://github.com/plotly/dash-table/issues/546)
- Visible columns are used correctly for both header and data rows

[563](https://github.com/plotly/dash-table/issues/563)
- Fixed a bug where any string beginning with a relational operator was being interpreted as that operator being applied to the rest of the string (e.g., "lens" was interpreted as "<=ns")

[591](https://github.com/plotly/dash-table/issues/591)
- Fixed row and column selection when multiple tables are present

[600](https://github.com/plotly/dash-table/issues/600)

Added
[566](https://github.com/plotly/dash-table/pull/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/dash903](https://github.com/plotly/dash/pull/903) for more details.

[319](https://github.com/plotly/dash-table/issues/319)
- New 'loading_state' prop that contains information about which prop, if any, is being computed.

Fixed
[578](https://github.com/plotly/dash-table/pull/578)
- Fix [576](https://github.com/plotly/dash-table/issues/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](https://github.com/plotly/dash-table/issues/569), [#544](https://github.com/plotly/dash-table/issues/544)
- Allow empty strings in all `filter_query` (e.g filter_query: '{colA} eq ""')

[567](https://github.com/plotly/dash-table/issues/567)
- Add support for missing `border-radius` in style_** props

- Fix row selection vertical and horizontal alignment

[103](https://github.com/plotly/dash-table/issues/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](https://github.com/plotly/dash-table/issues/583)

- New `derived_viewport_selected_columns` that contains the list of visible columns that are currently selected
This prop is read-only. Use `selected_columns` in callbacks instead.

Fixed
[533](https://github.com/plotly/dash-table/issues/533)
- Fixed problem clearing one column shifting everything to the left and
leaving the last column blank

Added
[314](https://github.com/plotly/dash-table/issues/314)
- New `column.hideable` flag that displays an "eye" action icon in the column
Accepts a boolean, array of booleans, 'last' or 'first'. Clicking on the "eye" will add the column to the `hidden_columns` prop.
`hidden_columns` can be added back through the Columns toggle menu whether they are hideable or not.
- New accepted values for `column.clearable`, `column.deletable` and `column.renamable`
These props now also accept 'last' and 'first'.

row of `data`.
- Additionally clearing the column will reset the filter for the affected column(s)

[318](https://github.com/plotly/dash-table/issues/318)
- Headers are included when copying from the table to different
tabs and elsewhere. They are ignored when copying from the table onto itself and
between two tables within the same tab.

Changed

- Like for clearing above, deleting through the "trash" action will also
reset the filter for the affected column(s)
