v1.0.0-beta21 (2024-08-26)

📦 Available on Clojars: Telemere and SLF4J provider.
Uses Break Versioning.

---

This is a pre-release intended for early adopters and those who'd like to give feedback. New betas will be released frequently, while I continue to fix issues and make other improvements/additions.

The included handlers and utils are still undergoing changes, though the signal creator and signal content APIs should already be mostly stable.

Please report any unexpected problems on GitHub or the Slack channel, thank you! 🙏
