 What's new in Periscope.
 
+## 2.74.0 — 2026-09-22 — Protocol packs from recovered PDFs (USB CTS, Type-C FTS, DVI 1.0, IEEE 802.3-2012 §2)
+
+NUMERIC constraints now carry title, revision, section/table, and page from the recovered PDFs. USB 2.0 HS fills data rate / rise-fall / 1.5 kΩ pull-up / DCR from Electrical CTS v1.08; Zdiff stays UNKNOWN (CTS does not state 90 Ω). Type-C Rp/Rd/VBUS volts stay UNKNOWN (Functional Test Spec points at Cable and Connector tables). DVI 1.0 is a separate protocol from HDMI. IEEE 802.3-2012 Section Two fills 100BASE-TX cabling 100 Ω / 100 m / isolation and 100 Mb/s; 10BASE-T Clause 14 and 1000BASE-T Clause 40 are not in Section Two.
+
+- [Changed] `protocol_catalog.py` + `catalog.json`; DVI recognition.
+- [New] pytest `tests/pcb/test_protocol_pdf_pack.py`.
+
 ## 2.73.0 — 2026-09-22 — Protocol certification M6/M7 (USB-C / Ethernet / HDMI packs)
 
 USB 2.0 (LS/FS/HS) is the protocol; USB Type-C is a connector/interface system; USB 2.0 over Type-C is the physical implementation. Type-C does not imply USB3 or USB4. Mini HDMI is a connector, not a protocol. Ethernet variants (10/100/1000/2.5G/5G/10G, SGMII, 1000BASE-X, 100BASE-FX, 10GBASE-R) are incomplete skeletons. All listed numeric fields stay **UNKNOWN** with `needed_document` (USB-IF / IEEE 802.3 / HDMI Adopter). No invented ohms, no typical-as-standard, no OpenEMS.
