# Breaking: #78581 - FlexFormTools public properties dropped {#breaking-78581-1668719184}

See [forge#78581](https://forge.typo3.org/issues/78581)

## Description {#description}

Two public properties have been dropped from PHP class `FlexFormTools`:

-   `FlexFormTools->traverseFlexFormXMLData_DS`
-   `FlexFormTools->traverseFlexFormXMLData_Data`

## Impact {#impact}

Accessing those properties will throw a warning.

## Affected Installations {#affected-installations}

Extensions that access these properties. These two properties were of little use from an extensions point of view,
it is very unlikely this actually breaks an extension.

## Migration {#migration}

No migration possible.
