ReleasePort's take
Moderate signalTailscale v1.98.3 removes legacy authentication protocol support and adds DNS-over-HTTPS (DoH) for Tailscale nodes, while fixing a VPN tunnel manager memory leak and reducing handshake latency by 40%.
Why it matters: Patch to v1.98.3 immediately if using the legacy authentication module; plan migration to DoH before deprecation; test the memory‑leak fix in dev environments; expect faster handshakes post‑upgrade.
