Important: #89645 - Removed systemLog options

See forge#89645

Description

The systemLog API has been changed in TYPO3 v9.0 to use the Logging API as a breaking change. The relevant systemLog options have been kept in TYPO3 v9 for backwards-compatibility of existing extensions, however have no use in TYPO3 v10 anymore.

The affected options are:

  • $GLOBALS['TYPO3_CONF_VARS']['SYS']['systemLog']

  • $GLOBALS['TYPO3_CONF_VARS']['SYS']['systemLogLevel']

Impact

The options have been removed from the TYPO3's default configuration. When the options have been set, they are automatically removed in TYPO3 v10.0 when accessing the Install Tool or System Maintenance area.

For extension authors, the Logging API should be used starting with TYPO3 v9. The usage of the systemLog options should then be removed from the extensions' code.
