May 2026 - Dashboard Release Notes

Resolved a Null Pointer Exception with connected data connections entering the dashboard configuration screen after refreshing the dashboard.

Resolved a performance issue when using very large numbers of database columns which occurred as part of updates to the configuration of frameworks.

Currently, most of our inner-chart elements which are style-able by a class within the themes are straightforward HTML elements. Now, with x-axis related classes, we allow Highcharts to automatically convert these elements to SVG elements, and apply the styling as inline styling rather than via the class. The affected classes are:

• pi-style__chart__x-axis-title

• pi-style__chart__x-axis-value

• pi-style__chart__null-x-axis-value

The reason for this is that chart-related styles were being lost upon export. Now, exported charts containing styled x-axis items will retain their styling applied at both the theme and chart level. This is consistent across browser exports, scheduled exports, report exports and scheduled report exports.

Style properties which have an SVG equivalent will be converted, e.g. 'color' will be converted to 'fill'.

The following style properties have no SVG equivalent and will therefore be lost:

We aim to gradually roll this change out across all chart-related style classes so that styles will no longer be lost upon export.

Previously, the following style classes were applied to SVG elements rather than the standard HTML elements that most style classes are applied to:

• pi-style__chart__pie-and-donut__data-value

• pi-style__chart__donut__total-data-value

• pi-style__chart__target-line-label

Now, they follow the same functionality outlined in release item pi#3539, and are HTML elements which are automatically converted to SVG by Highcharts, with their styles being applied inline, so that they are not lost upon export.

Previously, on these unique classes, you’d have to specify SVG-specific style properties such as 'fill' instead of 'color'. Now, HTML style properties which have an SVG equivalent will be automatically converted, i.e. 'color' will be automatically converted to 'fill'.

All of the styles without an SVG equivalent mentioned in release item pi#3539 will be lost.

A new type of indicator has been added to theme classes to signify that certain classes are automatically converted from HTML to SVG by Highcharts. This is done to retain styling upon export. This indicator has been applied to the classes mentioned in release itempi#3539 and pi#3542. The following classes are affected and therefore now have this indicator:

• pi-style__chart__x-axis-title

• pi-style__chart__x-axis-value

• pi-style__chart__null-x-axis-value

• pi-style__chart__pie-and-donut__data-value

• pi-style__chart__donut__total-data-value

• pi-style__chart__target-line-label

A feature permission has been added to enable the three currently supported AI features: Chart Finder, Chart Description & Report description tools. This is available to both users and roles. It is off by default due to cost and performance overheads, and includes a warning indicator to outline this.

To provide greater insight into the usage of AI features, which is especially important since they have direct performance and cost implications when used, we have added a comprehensive audit system in the repository database in line with the existing audit data that is already there. There is now a record created for each interaction, providing information on the user, the action invoked, an API key identifier (the last 6 characters of the API key) and token usage. You can use your repository data connection to build out charts, tables and reports around this data.

Improvements have been made to the Renderer in terms of:

• Mitigating the possibility that a download completes prior to the ‘watcher’ being established to confirm it has succeeded. This potential race condition may have resulted in some exports failing due to timeouts, even though the file was created and fetched correctly.

• Improved logging capabilities, including the addition of a reqId to log messages to simplify tracing requests when multiple are processed simultaneously. Logging has also been enhanced with additional debug messages and updates to improve consistency, clarity, and overall usefulness.

Triggers that were set on the mis_licensesdatabase table have now been removed as they related to a caching mechanism that has been rewritten. Licence data is cached both in node on a short-term basis and in the database for a longer period.

Despite rendering correctly on the Dashboard UI, charts using custom SQL that defined an alias, that did not match up to any data object defined on the chart would produce a corrupted CSV export. This has now been resolved.
