 acquisition metadata with the pixel size), generic HDF5 read, append and write sessions, the BraggVectors writer, `FormatoLoader.sniff/load` over them, and `Peek` (one decimated frame and the header facts of a file, for Quick Look). Timings against
 RosettaSciIO: `docs/benchmarks.md`; what is open: the GitHub issues (the GMS EDS geometry needs a real file; DM and TIFF read speed); known limits: `docs/parity.md`.
 
+Since 0.11.0: 0.12.0 (2026-10-31) added the readers above, bounded the Velox metadata and frame counts a file can ask for, dropped the internal-only public helpers and tiled the DM4 scan-fastest gather (whole scan 420 ms to 68 ms); 0.12.1 (2026-11-01) made the reader notes state what is known. Details and the migration notes: `CHANGELOG.md`.

 Test split (2026-10-21): the comparisons with the pinned RosettaSciIO and Pint values (`PinsTests`, `SpectrumImagePinsTests`, `UnitsTests`, `FormatoTIFFPinsTests`) and the inherited golden baseline are the `FormatoKitParityTests` target (fixtures stay in `Tests/Formato*Tests/Fixtures`, found through `FormatoKitTestSupport`); `tools/test.sh --parallel --skip FormatoKitParityTests` (or `swift test -c release --parallel --skip FormatoKitParityTests`) is the per-session gate (380 tests), plain `tools/test.sh --parallel` the full suite (396 tests: 380 fast + 16 parity, counted with `swift test list` at 0.11.0). The HDF5 exit-barrier test needs `tools/test.sh` (it sets `FORMATO_HDF5_PATH`). Timings of 2026-10-21 (Mac, release, warm build): fast target 8.2 s, full suite 9.4 s through `tools/test.sh`.
