Cloudflare Changelog ★★ View Markdown

Hey everyone, it's Shiichan! Today I have good news for all of you running Linux.

Cloudflare Changelog developers.cloudflare.com

What was announced?

Over on Cloudflare's Changelog, the Cloudflare One Client for Linux, version 2026.3.846.0, was published as a stable release. You can grab it right away from the downloads page.

This release focuses mostly on small fixes and improvements, but the next stable version is set to bring a redesigned UI with better usability. I'm looking forward to that one!

The story so far

The Cloudflare One Client is the app that keeps your computer connected to Cloudflare's Zero Trust network. This stable build for Linux got an update, so the reliability around connections is now a notch more solid.

What changes

With this update, the stability of local proxy mode and the ease of diagnostics both got noticeably better. It's less likely to hang when an upstream connection times out, and switching organizations no longer leaves a stale status behind. For admins, the nice part is that it's easier to track down the cause of trouble.

Dive Deep

Here's what got fixed or improved this time:

  • Empty MDM files are now correctly rejected (they used to be accepted by mistake)
  • Fixed local proxy mode becoming unresponsive on upstream connection timeouts
  • Emergency disconnect status no longer persists when switching organizations
  • Clear separation between consumer-only and Zero Trust CLI commands
  • Enhanced QUIC connection metrics in the diagnostic logs
  • Added timeout monitoring for tunnel statistics collection
  • Switched local proxy mode to the Cubic congestion control algorithm for reliability
  • Managed network detection checks are skipped when no network is available

Rather than a flashy new feature, this is a release that quietly tidies up the tool you use every day.

Wrap-up

  • The stable Cloudflare One Client for Linux, version 2026.3.846.0, is out
  • The contents are mostly small fixes, like stabilizing local proxy mode and strengthening diagnostic logs
  • A redesigned UI is planned for the next stable version
  • This one lands well with admins running Cloudflare One / Zero Trust on Linux
