What is FOSSA CLI?

Ecosystem-by-ecosystem parser coverage is the whole roadmap.

fossa-cli releases every one to two weeks, and nearly every change is about correctly reading one more package manager's metadata. In this window alone: pnpm lockfile handling refactored, npm v3 lockfiles taught target-level dependency scoping, Node workspaces matched when declared with a leading ./, sbt 1.4+ routed through DependencyTreePlugin, Conan list-valued licenses handled, and container scanning extended to /var/lib/dpkg/status.d.

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.

5.0

Ecosystem-by-ecosystem parser coverage is the whole roadmap.

◆ Current state

fossa-cli releases every one to two weeks, and nearly every change is about correctly reading one more package manager's metadata. In this window alone: pnpm lockfile handling refactored, npm v3 lockfiles taught target-level dependency scoping, Node workspaces matched when declared with a leading ./, sbt 1.4+ routed through DependencyTreePlugin, Conan list-valued licenses handled, and container scanning extended to /var/lib/dpkg/status.d.

◆ Where it's heading

This is the unglamorous core of dependency scanning: correctness depends on parsing every ecosystem's format exactly, and every ecosystem keeps changing its format. The work arrives as many small, ticket-tracked strategy fixes rather than architectural change, and it comes from a mix of regular maintainers and first-time contributors. Some releases exist only to cut a version.

◆ Prediction

Expect the same cadence of per-ecosystem parser fixes to continue, since that is what every release in this window consists of; nothing in the entries points to a structural change in how strategies are implemented.

2.5

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.
