Zig is still a relatively young programming language and yet to reach a 1.0 release. This is why it’s rapidly evolving and breaking changes between releases are expected. This makes it a hard moving target when trying to develop and maintain learning resources about the language and its ecosystem. Nevertheless, there are already some very good resources available and we invite the community to add their own and help keep this list up-to-date. The list is not in any particular order to make it easy to add and remove items without having to break out a sorting algorithm. 
Also be sure to check out the learning resources list over at the official Zig project website.
