-### 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).
