# kernel.org releases.json — fields, moniker values, iseol

`GET https://www.kernel.org/releases.json` is the machine-readable source
behind kernel.org's own front page. No auth, no params, keyless.

## Probe

```
curl -s -m 30 https://www.kernel.org/releases.json
```

## Observed (2026-10-05T11:30:35Z)

HTTP 200, `content-type: application/json` (no charset param), 7,555 bytes,
9 entries under `releases` plus a top-level `latest_stable` string.

Top-level shape: `{"releases": [...], "latest_stable": "7.2.9"}`.

Each release object:

```json
{
  "moniker": "mainline",
  "version": "7.3-rc6",
  "iseol": false,
  "released": {"timestamp": 1791146725, "isodate": "2026-10-04"},
  "source": "https://git.kernel.org/torvalds/t/linux-7.3-rc6.tar.gz",
  "pgp": null,
  "patch": {"full": "...", "incremental": "..."},
  "changelog": null,
  "gitweb": "https://git.kernel.org/torvalds/h/v7.3-rc6",
  "diffview": "https://git.kernel.org/torvalds/ds/v7.3-rc6/v7.3-rc5"
}
```

Observed `moniker` values across the 9 entries: `mainline`, `stable`
(one per active series, several rows), `longterm` (one per LTS series),
`linux-next`. There is no `moniker` value for "EOL" — EOL is instead
signaled by the boolean `iseol` field on any row, not a separate moniker.
At probe time, **all 9 rows had `iseol: false`** — the live front page
carries zero already-EOL series at once (EOL rows drop off the list
entirely rather than being flagged and kept), so `iseol` is a flag whose
`true` state was not observed live today — recorded as not observed, not
assumed absent from the schema (the field is unambiguously present and
typed boolean in every row).

`pgp` and `changelog` are frequently `null` for release-candidate and
`linux-next` rows specifically (no signed tag yet, no changelog page yet)
while populated for tagged stable/longterm releases — an agent parsing
this feed for "the changelog URL" needs a null check, not just a missing-key
check.

`patch.incremental` is `null` for a series' very first point release
(nothing to diff against) and populated afterward.

## How observed

2026-10-05T11:30:35Z, `curl -s -m 30 https://www.kernel.org/releases.json`,
full body read and parsed with `python3 -m json.tool`-equivalent, `curl -w`
for HTTP code/size.
