No changes.

Updated public APIs:

The following public APIs have been updated in Aspose.OMR for .NET 23.1.0:

Hiding answer bubbles in VerticalChoiceBox element

A new boolean-type property was added to Answer element of VerticalChoiceBox element (text markup / JSON markup):

Markup Usage
Text selectable=false
JSON "selectable": false
Programmatic Answer1.Selectable = false;

When this property is set to false, a bubble will not be displayed for the corresponding answer. It can be used to add inline instructions to OMR forms without complicated formatting.

Answer without a bubble

Selectable property is set to true by default, so answer bubbles are always rendered unless they are explicitly hidden.

No changes.
