Mostly fixes, a few breaking changes (below in the TL:DR) and a few cool features.
all release-notes available here.
TL;DR:
new cool random seeding for all rng dependant algo
better (s)kmean seeding
The only breaking changes are highlighted in there:
C++: some class signatures
SC: parameter order for seeding objects
PD: latency gets a proper message output instead of just a number to be consistent and future-proof
