+## v0.12.6 — 2026-05-01
+
+### Fixed
+
+- **`blastware_file.py` — waveform frame classification** — A5 frame classification for
+  waveform-only vs header-only frames now uses `frame.record_type` instead of frame index.
+  Only waveform frames (0x46) are written to the file body; metadata frames are skipped.
+  Fixes spurious data corruption from incorrectly classified frames.
+
+- **`s3_analyzer.py` — A5/5A frame naming** — Bulk waveform stream frames (SUB 5A response)
+  are now correctly labeled "A5" in analyzer output instead of being conflated with other
+  multi-frame responses (SUB A4, E5, etc.).
+
+- **`S3FrameParser` — frame terminator detection** — Corrected the bare ETX terminator
+  detection. Frame termination is now correctly identified by a standalone `ETX=0x03` byte,
+  not by the `DLE+ETX` sequence (which is part of the payload when it appears within a frame).
+
+---
+
 ## v0.12.5 — 2026-04-21
 
+### Added
+
+- **`seismo_lab.py` — Download tab** — New fourth tab for live wire-byte capture during event
+  downloads. Captures both BW→device and device→S3 frames in real time, allowing inspection
+  of the 5A bulk stream chunk sequence and frame-by-frame analysis without needing a bridge
+  or MITM proxy. Files are saved with user-specified labels for easy tracking.
+
 ### Changed
 
 - **`s3_bridge.py` — raw captures always-on by default** — `--raw-bw` and `--raw-s3` now
@@ -17,6 +43,10 @@ All notable changes to seismo-relay are documented here.
   "S3→BW raw" checkboxes start checked. Path fields are empty by default (bridge auto-names
   the files). Unchecking a box passes `--raw-bw ""` to explicitly disable capture.
 
+- **`Bridge tab` — TCP mode added** — Serial/TCP radio toggle allows connection via cellular
+  modem (RV50/RV55) instead of direct RS-232. Supports multi-capture design (simultaneous
+  Bridge + Analyzer + Download sessions).
+
 - **`ach_server.py` — TX capture added (`raw_tx_<ts>.bin`)** — Every ACH inbound session
   now saves both directions: `raw_rx_<ts>.bin` (device → us, S3 side, as before) and
   `raw_tx_<ts>.bin` (us → device, BW side). Both files are usable in the Analyzer.
