There is no single healthy release cadence. A parser or framework usually ships often, while a small, finished utility may go quiet for long stretches. What matters is whether the rhythm fits the package's job and whether it suddenly changes. A recent release within twelve months is the OpenSSF baseline.
What the guidance actually says
The OpenSSF Concise Guide for Evaluating Open Source Software lists two related rules. Release Recency asks you to confirm the last release was issued within the previous 12 months. Communication asks you to verify recent releases or announcements from the maintainers. It also asks whether the version string signals instability, for example a leading zero or an alpha or beta label.
Those are floors, not targets. They filter out the obvious cases, such as a package whose last release is years old and whose API has moved on.
Match cadence to what the package does
| Package type | Reasonable rhythm | Why |
|---|---|---|
| Network or parsing library | Frequent patch releases | Handles untrusted input, so fixes matter |
| Framework or runtime plugin | Regular minor releases | Tracks platform changes |
| Small finished utility | Rare releases | Little to change |
| Build or CI tool | Frequent, watch closely | Runs with your secrets and source |
The Scorecard documentation makes the same point about maintenance. A library that decides whether an integer is even would not normally need maintenance unless the language definition changed. A lack of activity is a reason to investigate, not a conclusion.
Cadence changes tell you more than cadence
Compare a package against its own history. Three changes are worth a second look:
- A long silence, then a release with no changelog or issue discussion.
- A burst of releases in a short window after months of calm.
- Releases that skip the project's normal path, for example no matching tag or no linked build.
Each can be harmless. A maintainer may have returned from leave, or a security fix may have needed several quick patches. The point is to notice, then read the diff and the release notes before you adopt the update.
How to measure it in practice
The deps.dev API returns a publish time for each package version, as reported by the package registry. List the last 20 versions, sort by date and look at the gaps. Do the same for the versions you already run. If your lockfile pins a version that is two years behind the latest, the cadence signal is telling you about your own lag as well.

Where Safeguard fits
Safeguard provides SBOM and dependency scanning plus policies and gates, so a rule such as review new major versions before merge can be written down and enforced. A free scan is at gold.safeguard.sh/scan.
Quick check
Is a daily release schedule a warning sign?
Not by itself. Some projects release automatically from every merge. Check whether releases are built by a documented pipeline.
Is a version starting with 0 unsafe?
No. It signals the API may change, which makes upgrades harder, so plan for that.
