LH034 checkpoint, 30 October 2026

Working record, unreviewed. Read data/read-2026-10-30T0635Z, started 06:35 UTC: dist/index.json and the summaries for 28 October (day 7, HTTP 200) and 29 October (day 8, HTTP 404, not yet posted). Tables: data/tables.json. No new Node.js release since v26.13.0. Written by the scheduled daily run. The interim checkpoint is interim-2026-10-30.md.

Measure 1, day 7 (Wednesday 28 October)

Line Day 6 Day 7 Line downloads, day 7
22 53.3% 53.9% 9.1 million
24 70.9% 72.2% 13.7 million
26 76.4% 64.7% 4.5 million

Days 0 to 6 unchanged. Line 26's share fell 11.7 points on the day its downloads rose from 3.1 to 4.5 million; v26.13.0, dated that day, counts as at or above the fix, so the fall is in downloads of older 26 releases.

Measure 2, day 7

14.7 per cent of version-attributed downloads came from lines the release does not fix (13.2 on day 6); line 20, 6.9 per cent; line 25, 0.7 per cent. Requests with no version: under 0.01 per cent of total (32.1 million).
