I have just released version 0.3.0 of collections.nim and reactor.nim libraries!
reactor.nim is an alternative asynchronous networking engine for Nim based on libuv. The main addition in this release is much improved documentation ([Github](https://github.com/zielmicha/reactor.nim), [tutorial](https://networkos.net/nim/reactor.nim/doc/tutorial.html), [API docs](https://networkos.net/nim/reactor.nim/doc/)). collections.nim is a collection of several mostly independent module ([Github](https://github.com/zielmicha/collections.nim), [API docs](https://networkos.net/nim/collections.nim/doc/)). Notably, is has [weakref](https://networkos.net/nim/collections.nim/doc/api/collections/weakref.html) module that implements weak references and [pprint](https://networkos.net/nim/collections.nim/doc/api/collections/pprint.html) which is a more readable alternative to built-in repr.
