Breaking: #102151 - XML prologue always added in flexArray2Xml()¶
The second argument
$addPrologue = false on
has been dropped: When imploding a flex form array to an XML string using
this method, the "XML prologue" is always added.
This should have no impact for consumers of this method. The counterpart method
TYPO3\CMS\Core\Utility\GeneralUtility::xml2array() happily deals with this.
Instances with extensions using
FlexFormTools->flexArray2Xml() can drop
the second argument. The extension scanner will find usages with a weak match.
Since this is a detail method of the TYPO3 core flex form handling, not often handled by extensions themselves, few instances will be affected in the first place.
No data migration needed, PHP consumers should drop the second argument when calling the method.
