   A new API for upgrade wizards was introduced:
   :doc:`ext_core:Changelog/9.4/Feature-86076-NewAPIForUpgradeWizards`
   This chapter was updated to use the new API.

TYPO3 CMS offers a way for extension authors to provide automated updates for
extensions. TYPO3 itself provides upgrade wizards to ease updates of TYPO3
versions. This chapter will explain the concept and how to write upgrade
wizards.
