 - `qrlink()`: the QR code svg now carries a viewBox and scales to the box it is placed in. Without one, a code sized down by CSS -- as on the title slide -- kept drawing at its full 300px and only its top left corner remained visible. The svg is cropped to the code's dark modules, so its quiet zone comes from the surrounding layout (the white plate behind the title slide's code, and `padding` on `a.qrcode` elsewhere).
 
+- Auto-generated Overview slides: the table of contents now renders at the normal slide body size and in the theme's link colour, so its entries look like the navigation links they are (they were set to 0.72em and to `color: inherit`, which made them read as smaller, darker body text). Only the denser two-column variant with sub-headings is still scaled down. The section was also missing from the theme's scss source, where it has now been backfilled.

 - New `df_print` option (default `"kable"`): data frames are now printed as theme-styled HTML tables by default, so raw results on slides look reasonable without extra code. Use `df_print: default` for plain text output (or `tibble` / `paged` as in `rmarkdown::html_document`); `"kable"` prints all rows, so show only `head(x)` on slides with many-rowed results.
 
 - New transcript view, toggled with `r` (or, on touch devices, with a list button next to the speaker notes button): a single scrollable page containing every slide's content and speaker notes. Text-to-speech ("read aloud") browser extensions cannot walk a reveal.js deck (hidden slides are not part of the visible page text), but they can read the transcript from start to finish -- e.g. to have the whole talk including notes read aloud while practicing.
