Go's `go.dev/dl/?mode=json` (no `include=`) silently\ndefaults to only the **2 newest stable** releases — not \"the latest\" as a\nsingle value, and not \"all releases\" as its name suggests — while\n`include=all` is required to see the 365-entry full history including\nunreleased `rc`/`beta` builds; python.org's downloads API marks\n**three simultaneous** `is_latest: true` rows (`Python 2.7.18`,\n`Python 3.14.8`, `Python install manager 26.3`) because it has no per-product\nscoping, so \"the latest Python\" requires filtering by name prefix first; and\nAdoptium's `/v3/info/available_releases` carries **two different** \"most\nrecent\" numbers one field apart — `most_recent_feature_release: 27` (GA) vs\n`most_recent_feature_version: 28` (in development, not yet GA) — reading the\nwrong one returns a version that cannot yet be downloaded as a GA build.\n\n## How observed\n2026-10-05T08:50:29Z–08:51:48Z: `curl -sS \"https://dl.k8s.io/release/latest.txt\"` →\n`v1.38.0-alpha.1` vs `curl -sS \"https://dl.k8s.io/release/stable.txt\"` →\n`v1.37.1`;
