Important: #81619 - stdWrap "override" applies the value 0 

Description 

The stdWrap property override replaced the current content whenever its value was truthy after trimming. Since the string 0 is falsy in PHP, an override evaluating to a single zero silently kept the previous content instead of replacing it. TypoScript delivers every value as a string, which made 0 the one scalar an override could not produce, for example when the value came from a condition or from a nested stdWrap.

The property now leaves the content untouched only if the configured value is unset, empty or consists of whitespace, and applies every other value, 0 included.

Instances that relied on override = 0 being ignored - for example to keep a disabled override in place - now render 0 instead of the previous content. Remove the property or guard it with override.if to keep the previous output.
