+### Changed
+
+- A zoom step sets the column widths with the list's redraw off, gives the new
+  fonts to the rows and their titles only, and paints once. It no longer
+  rebuilds and repaints the whole window.
+- Ctrl+wheel notches already queued are taken as one zoom change.
+- Each column keeps the width it was designed at, so zooming in and out no
+  longer makes widths drift. A width set by hand becomes the new basis.
+- Columns of a file opened while zoomed are sized for that zoom.
+- The rows and the settings shortcut list have thin scroll bars in the theme's
+  colours, without arrow buttons, as in LeanMark. High contrast keeps the
+  system scroll bars.
+- The settings shortcut list fits its width: long actions wrap onto a second

+# LeanRows 0.5.1
+
+LeanRows 0.5.1 makes zooming fast and gives the lists thin scroll bars.
+
+Everything from 0.5.0 works as before.
+
+## Zoom
+
+- A zoom step now changes only the rows and their column titles and paints
+  them once. In 0.5.0 a step repainted every visible row once per column
+  and then the whole window.
+- A fast spin of `Ctrl` and the mouse wheel is taken as one change, at the
+  level the spin ends on.
+- Column widths no longer drift when you zoom in and out. A column you
+  widened by hand keeps its width, scaled with the zoom.
+- A file opened while zoomed gets columns sized for that zoom.
+
+## Scroll bars
+
+- The rows and the settings shortcut list have thin scroll bars in the
+  theme's colours, without arrow buttons, as in LeanMark. A thumb grows a
+  little under the mouse.
+- Dragging the thumb, clicking or holding the track, the wheel, the keyboard
+  and touch scroll as before.
+- With Windows high contrast on, the system scroll bars and colours come back.
+
+## Settings
+
+- Every shortcut in the settings panel fits its width. A long action wraps
+  onto a second line instead of being cut off, and the list has no sideways
+  scroll bar.
+
+## Measured
+
+On the maintainer's laptop, 0.5.0 and 0.5.1 built and measured the same way,
+in a 1400 x 900 window:
+
+| Measure | 0.5.0 | 0.5.1 |
+| --- | --- | --- |
+| Zoom step, six-column 2 MB file, median / p90 | 285 / 379 ms | 31 / 50 ms |
+| Zoom step, 10M-row two-column file, median / p90 | 115 / 155 ms | 21 / 24 ms |
+| 8 Ctrl+wheel notches at once, until painted, 2 MB file | 1,234 ms | 22.5 ms |
+| Ctrl+Plus held for 8 repeats, wait after the last, 2 MB file | 1,038 ms | 1.3 ms |
+| Page Down, 10M-row file | 20.4 ms (20.0 to 21.7) | 21.0 ms (21.0 to 21.2) |
+| One wheel notch, 10M-row file | 2.45 ms (2.40 to 2.60) | 2.07 ms (2.00 to 2.22) |
+| Open the 10M-row file until the row count settles | 3,957 ms | 3,966 ms |
+| Start to input idle, no file | 285 ms | 281 ms |
+| Start to input idle, the 10M-row file | 428 ms | 425 ms |
+| Peak working set, the 10M-row file open | 18.0 MiB | 18.0 MiB |
+| Peak private bytes, the 10M-row file open | 3.3 MiB | 3.3 MiB |
+| Executable size, local build | 986,112 bytes | 1,024,512 bytes |
+
+Zoom steps are timed until the rows have painted. Page Down and the wheel are
+medians of 300 presses or notches in each of 3 alternating runs, with the
+range of the runs. Page Down is 0.6 ms slower: the thin bars repaint with the
+rows. Start numbers are medians of 7 starts. The zoom numbers on the 10M-row
+file are from a second run; in the first, single steps took up to 0.7 s on
+0.5.0 and 1.1 s on 0.5.1.
+
+## Known gaps
+
+- A zoom step is not under 16 ms: most of it is the list painting its rows,
+  which costs about as much as a Page Down. On a file with 64 columns a step
+  takes about 150 ms, because the list asks for every column of every
+  visible row.
+- The column titles' text does not zoom, although the title row grows.
+- The rows can show an empty sideways scroll bar when the columns' total
+  width falls within 7 pixels of the window's width.
+- High contrast, a change of display scaling and touch were not tried on
+  this release; they need system settings changed or a touch screen.
+- Sorting and Find do not work on `.xlsx` workbooks yet. Sorting says so
+  instead of sorting.
+- The installer and the Store package do not register `.xlsx`.
+- The full local QA run with a receipt, as recorded for 0.2.0, has not been
+  run for 0.5.1.
