While Qt 5.9.3 does not add any new functionality to the long-term supported Qt 5.9 series, it would appear to be a major bugfix release that adds more than 500 changes compared to the previous update, Qt 5.9.2, which is currently used by default in various Linux-based and other operating systems. Over 100 of these are only bug fixes, as the rest are various improvements that should add an extra layer of performance to your Qt 5.9 implementation.
