nom, the Rust parser combinators library, is now available at version 5. This is the most mature version of nom. This is the one that feels "done". This is the parser library that I wanted when I started nom 5 years ago. It's here at last.

I am a bit dissatisfied with the use of the Tragedy of the commons to represent issues with free and open source software development. It is not an abstract resource that can be depleted when overused. It is not magically maintained if left alone.

As the main developer of nom, the Rust parser combinators library, I'm usually happy to see other parser libraries appear in Rust. The language's strengths play well in that space, and writing parsers is a nice way to explore it.

I'm delighted to announce that nom, the extremely fast Rust parser combinators library, has reached major version 4.
