It's still not that very slurred, slow legato that people like in "cinematic" sounding libraries. It's more like the kind of legato that VSL always did for their strings, like Dimension Strings or Chamber Strings. It's smooth and nice, but still doesn't drag and doesn't slur. It still has that VSL aesthetic, so don't expect any 180° turns philosophy-wise.
The transitions now feel clearly better playability-wise. The cantabile is the best sounding, with nice, smooth transitions that are clearly more audible than the original transitions from the old patches, and it has a very nice "emotive" vibrato which was previosly lacking. The "normal" legato will still feel way too abrupt for most people who would expect this patch to be the "standard" patch for legato, but this one is actually way more useful for stuff where in older libraries, the detache would have been the articulation of choice.
So, I'd say I'm now actually quite happy with the SyS legatos. I always felt drawn to the library because of the general sound and the other articulations, but could never really use it due to the legato issues. The updates and fixes have now rejuvenated my interest. For perspective: for me, the best string library is Dimension Strings. Ahead of stuff like CSS or SCS, which I also own and love. With SyS, there's still things that need fixing IMO - like the sfz and fp patches - but it's now becoming something I can enjoy and work with.
But: it's still a VSL string library, which some will appreciate and other traditionally will not. If you don't have this 270 GB beast already installed on your drive anyway, and you expect a CSS or 8Dio sound from your legato, I'm not sure if re-downloading the whole thing is worth it.
