Just read through the so called 'Spring Core Update' patch notes, and well... it wasn't a long read. Part of it is just third-party fixes. Before, a regular patch had more fixes than this. And you are selling this as a core update? Fancy words and fluff, nothing more. I think many will find it somewhat disappointing. Change my mind.
To be honest, I didn't expect much from it as it weren't announced a lot during last months and almost got dropped out of nowhere. Looking at the recent roadmaps missing the 6 months plus category, we all should be able to see that the next big core update (excluding Formation Designer coming to consoles and Suspension Improvements) will be TSW5.
Not surprising the free updates are barely updates. When the paid updates are few more unreal engine features toggled on back port those to a couple older DLC, then we get some half implemented new feature or two.
