The last eight weeks since the last sprint release have been mainly used to further push the integration of Doctrine DBAL
as a database layer replacement. We’ve seen a lot of patches from a large amount of different contributors in a lot of corners of the TYPO3 core. However, there is still a lot to do. After all, there are more than 1700 places in the TYPO3 core where database access is needed - and all of them need to be changed.
The efforts to stabilize the future releases even further have continued by including more than 200 unit tests since TYPO3 v8.1. Additionally, a further quality assurance check was added by adding so-called “pre-merge” tests - checking the whole TYPO3 core before a possible change is added to the TYPO3 core. The test infrastructure was also optimized, the test tool PHPUnit was updated as well.
