Regenerated 2026-04-15. Counts include `.docx`, legacy `.doc`, and (for Rel-20)
paired `.zip` packages. Earlier revisions of this file counted only `.docx`,
which undercounted Rel-18 by ~560 specs and Rel-19 by ~75.
## Totals per release
| Release | .docx | .doc | .zip | Total |
|---------|------:|-----:|-----:|------:|

| Rel-20 | 42 | 6 | 48 | 96 |
Grand total: ~17,686 spec files across 13 releases (excludes `.yang`/`.yaml`
API artefacts and the backup snapshots under `*.backup-20260413/`).
## Notes
- **Rel-18** and beyond use the per-series layout (`Rel-XX/{NN}_series/`). The
older flat `Documents/` snapshot for Rel-18 is archived at
`releases/Rel-18.backup-20260413/` and is not part of the current totals.
- **Rel-18** extends past the usual 21-38 range: 41, 42, 43, 44, 45, 46, 48,
49, 51, 52, 55 series are present (mostly legacy `.doc`).
- **Rel-14** is the first release that includes `38_series` (5G NR).
- **Rel-19** skips `25_series` (UTRA legacy, frozen).
- **Rel-20** is partial and mixes `.docx` with paired `.zip` packages; likely
still ingesting.
- **Series 25** (UTRA) is present through Rel-17 but not in Rel-19+, consistent
with 3GPP deprecating it.
