What is Cloudflare Tunnel?

cloudflared's release feed is checksums and nothing else — until a release has to warn you off itself.

The tunnel daemon ships on a calendar-versioned cadence, roughly two to four releases a month. Nine of the last ten release bodies contain only SHA256 checksums for the packaged binaries across amd64, arm64, 386, arm, FIPS Linux and the macOS and Debian/RPM packages; no changelog text accompanies them. Whatever changed in a given version is not discoverable from this feed.

What is Prowler?

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

cloudflared's release feed is checksums and nothing else — until a release has to warn you off itself.

◆ Current state

The tunnel daemon ships on a calendar-versioned cadence, roughly two to four releases a month. Nine of the last ten release bodies contain only SHA256 checksums for the packaged binaries across amd64, arm64, 386, arm, FIPS Linux and the macOS and Debian/RPM packages; no changelog text accompanies them. Whatever changed in a given version is not discoverable from this feed.

◆ Where it's heading

The publishing pattern is stable and unlikely to change: release notes live elsewhere, and the feed functions as a distribution manifest. The one exception in this window is instructive — 2026.8.0 was amended after the fact to carry a known-issue warning, which is why it now carries a later timestamp than the 2026.8.1 release that superseded it. That is the only mechanism by which this feed communicates anything: a release gets edited when it turns out to be unsafe to run.

◆ Prediction

Expect continued checksum-only releases every two to three weeks, with substantive text appearing only when another regression forces a retroactive warning.

Prowler's assistant decides what to do with findings; the patches keep the scanner honest

◆ Current state

Prowler is shipping a minor release roughly weekly with patches filling the gaps. The agentic layer, Lighthouse, has moved from explaining findings to acting on them, with named skills attached to individual findings and every write path bound to the asking user's RBAC. Alongside that, 5.39.1 fixes an install path that had been quietly broken: 5.38.0 declared a cryptography floor its own dependencies capped below, so pip install prowler silently resolved back to 5.37.1.

◆ Where it's heading

Two tracks run in parallel and rarely overlap. The minor releases push the commercial agentic surface forward — triage skills, page context, the MCP tool set — while the patches defend the parts everyone uses: dependency resolution, container CVEs, and check correctness. That second track matters more than its version numbers suggest, because a security scanner reporting PASS when an API call failed is worse than one that errors. 5.39.1 fixes exactly that in the ECS task-definition checks, and makes the SES public-access check evaluate every identity policy rather than stopping at the first.

◆ Prediction

Expect the next minor to extend Lighthouse skills to groups of findings rather than one at a time, with patch releases continuing to absorb Trivy and base-image CVE churn.
