Is six healthy, maintained, and safe?
Maintained, but watch it — six has real signals (drift, thin maintenance, or advisories) worth tracking.
The verdict
On the OSPulse health scale, six lands at 55/100 — medium risk, computed deterministically from live PyPI release history, and the OSV vulnerability database. Maintained, but watch it — six has real signals (drift, thin maintenance, or advisories) worth tracking.
Nothing has shipped since 4 December 2024 — over a year ago (601 days) — which points to a dormant project. Historically it released far more frequently, so the current silence reads as a genuine collapse in velocity rather than a natural gap. PyPI doesn't expose a reliable maintainer count, so bus-factor isn't scored here — treat maintenance depth as unknown rather than assumed.
On the security side, OSV has no advisories on record for six today. That's reassuring, but "no known advisory" is not the same as "no vulnerability" — it only means nothing has been disclosed and indexed yet.
six is usable but carries real signals — pin versions, watch for new advisories, and keep a fallback in mind. This is a one-time snapshot of a single package — real projects depend on dozens or hundreds of packages, and any one of them can drift or be compromised between releases.

Frequently asked
Is six still maintained?
Partly — the most recent release was 4 December 2024 (601 days ago), so maintenance has slowed but not fully stopped.
Does six have known security vulnerabilities?
No advisories are currently recorded for six in the OSV database. That means none have been publicly disclosed and indexed — it is not a guarantee of safety.
Is six safe to use?
Maintained, but watch it — six has real signals (drift, thin maintenance, or advisories) worth tracking. OSPulse rates it 55/100 (medium risk) based on release recency, cadence and known vulnerabilities.
