`v2.8.0-beta1` (2023-09-27)

📦 Available on Clojars, this project uses Break Versioning.

This is an early maintenance and feature pre-release.
Please test carefully and report any unexpected problems, thank you! 🙏

The main improvement in this release is to make it easier to automatically get good performance from http-kit client + server. Virtual threads are now used by default for both client and server on Java 21+, otherwise the default worker pools are now automatically sized based on available processor count.

As before, you may still want to customize your request queue and/or worker threading - but the changes here make it much easier to get started with reasonable defaults.

As always, feedback welcome! Cheers :-)
