Refresh supports the development of TYPO3 extension independent of the TYPO3 versions. It is especially developed to enable a smooth transition for extensions, which should run from TYPO3 6.2 to 9.x. This is the DUMMY VERSION. DONT USE IT! Please use the sponsored version available at https://typo3-browser-forum.de/sponsoring/?tx_browser_pi1[itemUid]649
