## Topics on events

Event definitions can now be associated with specific topics, to filter and group events by relevance.

Topics can be used into [Algorithms](/docs/algorithms) to process only specific events, such as those that have Health or Quality as a topic. In the DPS you can filter and group events, this allows you to create very highly focused pages that include only data with regard to a reference topic (e.g. Maintenance).

## Add Button component

Instead of having the add button directly into the list widgets (e.g. Customer List), with the [Add Button](/docs/add-button) component, you can place it as standalone and customizable button, for instance into the control bar section of the page.

Or even, in the case of mobile access, as a floating button in the list.

## RegEx based constraint on properties

In the [property definition](/docs/properties) you can define a constraint based on regular expression.

This will prevent DPS users from entering values that are not valid for the intended format.

## Dictionary labels into placeholders

When defining notification messages, you can use placeholders based on metric [dictionary and thresholds](/docs/dictionary-and-thresholds). For instance, you can include the label or severity label associated to a certain metric value. In this way, the notification received by the DPS users will be more effective and easy to understand.

```plaintext
// TEMPLATE
The machine is in ${metrics.status.valueLabel} status.
The temperature of ${metrics.temperature.value}°C is ${metrics.temperature.valueSeverity}.

// RESULT MESSAGE
The machine is in ERROR status.
The temperature of 55.6°C is CRITICAL.
```

## Minor console improvements

- The control bar template can be defined at the view and page level to be inherited by each sub-page.
- When editing a simple condition of an event, the selection of metrics has been improved, making it easier to select even when there are hundreds of metrics.
- The metrics label is now visible directly on the metrics list pages. This makes it easy to find metrics, even when using the label.
