Recently there was this package announced as well:

> Hello everybody, We are glad to announce the package [SimilaritySearch.jl](https://github.com/sadit/SimilaritySearch.jl) package. The SimilaritySearch.jl package uses a graph index and search heuristics (beam search) to solve queries fast and accurately; the current version is auto-tuned for some minimum quality or for achieving a tradeoff between speed, accuracy, memory, and construction time (all of these are opposite objectives in this kind of algorithms). It has some level of multithreading support (searching and construction). Also, it …
