[ANN] http-2-next (0.4.0) released

* HoneyryderChuck / http-2-next · GitLab

http-2-next is a fork of the http-2 gem (GitHub - igrigorik/http-2: Pure Ruby implementation of HTTP/2 protocol),
a pure ruby HTTP/2 protocol implementation. I's goal is to address spec
compliance issues and missing features from upstream.

## 0.4.0

No API changes.

* `HTTPX::Buffer` has been removed, and was replaced by `String` usage with
an enhanced API via refinements.
* Using `String#byteslice` in significant chunks of the parsing process.
* Removed usage of `Time.now` and replaced it with monotonic time
calculations.

All of the above contributed to a massive reduction in memory usage and GC
pressure.
