What is Certbot?

Certbot is rebuilding its API around identifiers so certificates aren't only for domain names.

Certbot is on a roughly monthly minor cadence and the defining change in this window is IP address certificate support. 5.3.0 added the --ip-address flag for the standalone and manual plugins and began renaming the API's domain concept to identifier; 5.4.0 extended IP issuance to the webroot plugin. The other visible work is structural: the nginx and apache plugin code moved into the certbot package as extras, the pyOpenSSL dependency is being unwound through a series of deprecations, and certbot.ocsp is scheduled for removal from the public API.

What is Cloudflare Tunnel?

Ships on a calendar cadence and tells you nothing about what changed.

cloudflared tags releases on a date-based scheme — 2026.6.0 through 2026.7.3 — at roughly one to three per month. The release notes contain nothing but SHA256 checksums for the build matrix. There is no change description, no fixed-issue list, and no feature note in any entry in the visible window.

Certbot is rebuilding its API around identifiers so certificates aren't only for domain names.

◆ Current state

Certbot is on a roughly monthly minor cadence and the defining change in this window is IP address certificate support. 5.3.0 added the --ip-address flag for the standalone and manual plugins and began renaming the API's domain concept to identifier; 5.4.0 extended IP issuance to the webroot plugin. The other visible work is structural: the nginx and apache plugin code moved into the certbot package as extras, the pyOpenSSL dependency is being unwound through a series of deprecations, and certbot.ocsp is scheduled for removal from the public API.

◆ Where it's heading

The identifier rename is the tell — Certbot's data model assumed a certificate subject was a domain name, and IP address issuance forced that assumption out of the type system. Expect that refactor to continue reaching further into the plugin API, since get_chall_pref has already changed signature. In parallel the project is shedding dependencies and consolidating packaging: plugins as extras rather than separate distributions, pyOpenSSL functions deprecated batch by batch, and Docker images tracking new Python versions promptly. The releases have become small and predictable, with most content in the Changed and Fixed sections rather than Added.

◆ Prediction

Expect IP address support to reach the remaining plugins, following standalone and manual then webroot, and expect the pyOpenSSL removal to land as a major version once the deprecation cycle completes. Given 5.5.0 already deprecated certbot.ocsp for removal in the next major, that release is the one to watch for breaking changes.

5.0

Ships on a calendar cadence and tells you nothing about what changed.

◆ Current state

cloudflared tags releases on a date-based scheme — 2026.6.0 through 2026.7.3 — at roughly one to three per month. The release notes contain nothing but SHA256 checksums for the build matrix. There is no change description, no fixed-issue list, and no feature note in any entry in the visible window.

◆ Where it's heading

What the checksums do reveal is the shape of the distribution: packages for macOS as pkg and tgz on both architectures, Linux across 386, amd64 and arm64 as raw binaries, deb and rpm, and a separate FIPS-validated Linux build line. That FIPS variant shipping in every release points at regulated and government deployments as a supported constituency. Beyond packaging breadth, this feed does not support conclusions about product direction.

◆ Prediction

The date-based tags will keep arriving on the same monthly rhythm. What goes into them is not something this changelog reveals — readers who need that have to go to the repository's commit history instead.
