Bonjour 3.1.0.1 [exclusive] Jun 2026

Bonjour version 3.1 was a pivotal release for Windows interoperability, effectively democratizing Zeroconf technology for non-Apple hardware. It successfully abstracted the complexities of IP addressing and DNS resolution for the end-user. However, due to its age, version 3.1.0.1 lacks modern security hardening found in later builds. Organizations running this specific legacy version are advised to upgrade to the latest available build via Apple Software Update to mitigate risks associated with mDNS amplification and service spoofing.
