TYPO3 Core

In typo3/sysext/core/Classes/Core/SystemEnvironmentBuilder.php, function defineBaseConstants() sets
define('TYPO3_URL_DOCUMENTATION_TSREF', 'http://typo3.org/documentation/document-library/core-documentation/doc_core_tsref/current/view/'); define('TYPO3_URL_DOCUMENTATION_TSCONFIG', 'http://typo3.org/documentation/document-library/core-documentation/doc_core_tsconfig/current/view/');

That URL is no longer used ; the documentation now is on docs.typo3.org. Update it to point to
define('TYPO3_URL_DOCUMENTATION_TSREF', 'http://docs.typo3.org/typo3cms/TyposcriptReference/'); define('TYPO3_URL_DOCUMENTATION_TSCONFIG', 'http://docs.typo3.org/typo3cms/TSconfigReference/');
