Hi, folks, This week we released v0.1.0-alpha3
* Remove constrains on vectors, Simbase support arbitrary vectors now * Fix various bugs on memory structure to keep scale ratio linearly * Almost 7 times improvement on performance, right now it can handle 100k dimensional dense vectors in under 0.14 sec on a i7-cup mac laptop. >From now on, it enter the beta phase. If it is relevant to your work, we encourage you to have a try, and help us to find more bugs.
