Version: v1.0 (2026-01-01)

We currently support the last 3 minor versions of Halcyon with security and bug fixes.

We regularly perform patch releases for supported versions, which contain fixes for security vulnerabilities as well as important bugs. Prior releases might receive critical security fixes on best effort basis; however, it is not guaranteed that security fixes get back-ported to unsupported versions.

If you discover a security issue in Halcyon, please report it responsibly, giving us time to investigate and fix the problem. We’ll do our best to respond quickly and work with you on a solution; however, it may take a bit longer at times, so we appreciate your patience.

Security advisories are published via GitHub Security Advisories to ensure our userbase is abreast of such issues.

To report a vulnerability, open a GitHub Security Advisory.
