Hell yeah! A full brand new design.
No changelog? Acktchually, it would be the diff between this and the previous release.
TLDR: More 'memory safety' stuff, more fun ways to extend the base library and a lot cleaner code this time. The performance is also a bit more predictable now.
Oh and I got rid of the compression libs, so now lambda only depends on libstdc++, so it's pretty much zero-deps now!
