Important: #78650 - TypoScriptService class moved from Extbase to Core
See forge#78650
Description
The PHP class Typo
has been moved to the core extension, as it has no direct link
to Extbase, and a lot of other system extensions are using the class.
The old class name \TYPO3\
is registered as a class alias
for the new class name \TYPO3\
, so extensions can call the
class via the Extbase PHP namespace in TYPO3 v8 without any downsides.
