 ### 1.0.0-rc.166
 
-* `rugnux --mode calibration` writes `<prefix>.json` beside the `.poni`, whose `dataset_settings` member is a `jfjoch_broker` `dataset_settings` body as it stands.
-* `rugnux` and `jfjoch_viewer` read PILATUS miniCBF sweeps natively, without conversion.
-* Masters written by other facilities open, including Eiger 1.x and third-party NXmx variants.
+* `rugnux` reads PILATUS miniCBF sweeps natively, and opens masters written at other facilities, including Eiger 1.x and third-party NXmx.
 * `rugnux` measures the beam centre on every run, and indexes with it when the file's value indexes nothing.
-* A detector swung out on a 2theta arm is placed where the file says it stands, and the calibration can hold the tilt fixed.
-* `rugnux` writes the unmerged MTZ by default, and a P1 merge beside it, so a wrong space group can be re-merged without reprocessing.
-* Significant improvements to symmetry handling in `rugnux`: the lattice, the point group, the setting and the systematic absences.
-* The `rugnux` report gives the resolution the CC1/2 fit reached, beside the range the reflections were written to.
-* The `rugnux` report gives the twinning statistics measured before the space group was decided, beside the ones measured after.
-* The `rugnux` report gives the strong-direction diffraction limit, and warns when CC1/2 is not monotone with resolution.
-* `rugnux` ranks screw axes on the evidence their absences carry, rather than on how many control reflections a candidate happens to have.
-* The `rugnux` two-pass decision no longer reports a completeness it did not measure.
-* Twinning is no longer reported when the L-test contradicts it.
-* The `rugnux` report gives the detector tilt, the measured tilt and the direct beam beside the beam centre, and a post-refined beam centre is judged against the run's own measurement rather than the file's.
-* `--no-refine-tilt` holds the detector tilt at the value in the file, instead of zeroing it, when the calibration starts from the spots.
-* The HDF5 master file and the CBOR start message carry `direct_beam_x`/`direct_beam_y`, where the undeflected beam lands on the detector, beside the `beam_center_x`/`beam_center_y` PONI.
-* The `rugnux` report says what its measured detector tilt is worth: one sweep determines the direct beam rather than the tilt itself, and only the median over several crystals on one detector is comparable with a powder calibration.
-* The `jfjoch_viewer` grid scan view draws the cells in the proportion of the scan steps, so the map has the shape of the scanned area.
+* `rugnux` places a detector swung out on a 2theta arm where the file says it stands.
+* `rugnux` writes the unmerged MTZ by default, with a P1 merge beside it, so a wrong space group can be re-merged without reprocessing.
+* `rugnux` handles symmetry better: the lattice, the point group, the setting and the systematic absences.
+* `rugnux` reports the detector geometry it measured - the direct beam, the tilt and the beam centre - and what a single sweep can and cannot determine.
+* `rugnux` reports the resolution the CC1/2 fit reached and the strong-direction diffraction limit.
+* `rugnux` reports twinning measured before and after the space group was decided, and no longer reports it when the L-test contradicts it.
+* `rugnux --mode calibration` writes `<prefix>.json` beside the `.poni`, holding the geometry as a `jfjoch_broker` `dataset_settings` body.
+* `rugnux --no-refine-tilt` holds the detector tilt at the value in the file instead of zeroing it.
+* `jfjoch_writer` writes `direct_beam_x`/`direct_beam_y` in the HDF5 master - where the undeflected beam lands - beside the `beam_center_x`/`beam_center_y` PONI.
+* `jfjoch_broker` sends `direct_beam_x`/`direct_beam_y` on the CBOR start message.
+* `jfjoch_viewer` reads PILATUS miniCBF sweeps natively, and draws grid scan cells in the proportion of the scan steps.
 
 ### 1.0.0-rc.165
 This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use.
