Breaking: #75454 - TYPO3_db Constants removed¶
See Issue #75454
The PHP constants
which were used when TYPO3 initialized the database connection have been removed.
Checking for or using the mentioned constants may lead to unexpected behavior or errors. If not checked if the constant even was defined, the application will stop immediately.
Any installation which uses a third-party extension using these constants.
Use the configuration data within
to determine the username, password and host information for the default database connection.
