What's new in Periscope.
## 2.78.0 — 2026-09-22 — 1000BASE-T from IEEE 802.3-2012 Section Three
IEEE Std 802.3-2012 Section Three Clause 40 fills 1000BASE-T: 1000 Mb/s, 100 m Class D link, cable 100 Ω, MDI return loss 16 dB (1–40 MHz), pair skew 50 ns, isolation 2 MΩ / 1500 V rms, MDI peak 0.67 V, link delay 570 ns. Cable 100 Ω is **CABLE**; L2 PCB Zdiff stays UNKNOWN. Clause 36 fills 1000BASE-X 1000 Mb/s (optical Zdiff N/A). Insertion-loss formula not packed as a single dB.
- [Changed] `protocol_catalog.py` + `catalog.json`.
- [Changed] pytest `tests/pcb/test_protocol_pdf_pack.py`, `test_protocol_m6_m7.py`.
## 2.77.0 — 2026-09-22 — 10BASE-T from IEEE 802.3-2015 Section One
IEEE Std 802.3-2015 Section One Clause 14 fills 10BASE-T: 10 Mb/s, 100 m design-objective link, cable 100 Ω ± 15 Ω, 11.5 dB link insertion loss, MAU TD return loss 15 dB, isolation 2 MΩ / 1500 V rms, TD peak 2.2 V. Cable 100 Ω is **CABLE**, not L2 PCB Zdiff. 1000BASE-T (Clause 40) is not in this volume.
