Cloudflare One Client for Windows (version 2026.6.880.0)
A new GA release for the Windows Cloudflare One Client is now available on the stable releases downloads page.
This hotfix resolves a regression that caused a large increase in DNS-over-TCP queries to fallback and internal DNS servers. The client now sends fallback DNS queries over UDP first, falling back to TCP only when a response is truncated, instead of querying both protocols in parallel.
