## Changes in basic features {#base}



### Celebration UI theme {#festive-theme}

Added a setting to display the celebration UI theme: in the the left-hand panel, click ![image](../../_assets/console-icons/gear.svg) **Settings** → **Appearance** and select **Celebration theme**.

### Adding an anchor link {#anchor-link}

Now you can add anchor links to [dashboard](../dashboard/widget.md#title) headers. To add a link, enable the **Show anchor links** option in the widget editing window. Then you will see the `#` icon when hovering over a header with an anchor link. Clicking the icon adds a hash to the dashboard link. The page will scroll to that header when you click the anchor link.

### Setting up QL chart table size {#ql-chart-size}

Fixed applying the [table size setting](../visualization-ref/table-chart.md#table-size-settings) in [QL charts](../concepts/chart/ql-charts.md).

### Pivot table fixes {#pivot-table-fixes}

Fixed the following [pivot tables](../visualization-ref/pivot-table-chart.md) issues:

* Incorrect display of column names for `Date` type fields.
* Incorrect display of null values in rows.
* Totals displaying the first row only.

### Changes in area charts {area-chart-changes}

* Changed the **Stacked area chart** type name to [Area chart](../visualization-ref/area-chart.md).
* Added the **Stacking** [setting](../concepts/chart/settings.md#common-settings). It enables stacked or isolated data display for each category in the area chart. Available values:

  * **On**: Displays stacked data.
  * **Off**: Displays unstacked data.

### Coloring in selectors {#selector-color-accent}

Added the **Coloring** option to selector settings to highlight important selectors.

### Axis on chart {#axis-on-chart}

Fixed the issue with the **Axis on chart** setting where an axis reappeared when editing a chart again after setting the value to `Hide`.

### Maximum Y-axis value for normalized charts {#normed-charts-max-on-y}

Fixed the maximum **Y-axis** value for fields with fractional value in normalized charts. Now the default maximum value is `100`.

### Redesign of title and text settings {#title-text-settings-redesign}

Updated the design of [Title](../dashboard/widget.md#title) and [Text](../dashboard/widget.md#text) widget settings.

### Viewing change history of dashboard objects {#object-history-dashboard}

### _Readonly_ setting in a ClickHouse® connection {#ch-readonly-setting}

You can now use the **Readonly** setting in a [ClickHouse® connection](../operations/connection/create-clickhouse.md) to specify the permission level for queries to read data, write data, or modify parameters. This setting must not exceed the user's corresponding setting in ClickHouse®.

### Header size {#title-size-xl}

Added the `XL` text size for the [Header](../dashboard/widget.md#title) widget on dashboards.



## Changes available with the _Business_ service plan {#business}

### Changes in reports {#reports-changes}

* In a [report](../reports/index.md), you can now open the chart editing interface from the ![image](../../_assets/console-icons/ellipsis.svg) widget menu.
