+## [1.5.3] - 2026-05-10
+
+### Changed
+- **Forward log lines now distinguish histogram events from waveform-without-report.**  Previously every event without a paired `.TXT` report logged "no report", which on machines running histogram-mode units (extensions ending in `H`, e.g. `H907L1R7.PG0H`) generated alarming-looking lines on every single event when the lack of report was actually completely normal — Blastware doesn't auto-export ASCII reports for histograms.  Three log states now:
+  - **Waveform + paired TXT**: `+ <txt> attached`
+  - **Waveform without TXT**: `no report ⚠` (suggests checking BW's "Save Event Report" setting)
+  - **Histogram (any flavour)**: `(histogram, no report expected)`
+- New `is_histogram_event(filename)` helper classifies BW filenames by extension (4-char ext ending in `H` = histogram; old-firmware 3-char extensions remain unclassifiable and default to non-histogram for safe defaults).
+- 1 new unit test for histogram classification.

 Forwards each Blastware event binary (and its paired `<binary>.TXT` ASCII report when present) to an SFM server's `/db/import/blastware_file` endpoint, where the report is parsed and the rich per-channel stats (PPV, ZC Freq, Time of Peak, Peak Acceleration / Displacement, sensor self-check) land in a searchable database. **Default-off** — existing deployments keep their old behaviour after auto-updating until the operator opts in.
