This is a shop system extension for TYPO3 based on PHP 7 and PHP 8.
See the file manual.odt under the folder doc of the extension.
If you upgrade to a newer version of tt_products then you sometimes you must execute upgrade wizards in the TYPO3 Install Tool for tt_products. Do not forget to make a backup copy of the database before you execute them.
Only if you are still using TYPO3 < 9 you must execute the renaming of these database table fields manually in phpMyAdmin or a similar database tool.
