  • Slow printing of wide tibbles, tidyverse/tibble#360
  • Sometimes results in a delay between printing the body and the footer


  • unnecessary calls to pillar() for columns that are never shown
  • slow getOption() with default argument set
    • It is slow, but not *that" slow
  • unnecessary calls to crayon::make_style()

- `NA` values are now shown in plain red, without changing the background color (#70).

    - `pillar.sigfig` to control the number of significant digits, for highlighting and truncation (#72),
    - `pillar.subtle` to specify if insignificant digits should be printed in gray (#72),
    - `pillar.neg` to specify if negative digits should be printed in red,
    - `pillar.bold` to specify if column headers should be printed in bold (default: `FALSE`, #76),
    - `pillar.min_title_chars` to specify the minimum number of characters to display for each column name (default: 15 characters, #75).
- Shortened abbreviations for types: complex: cplx -> cpl, function: fun -> fn, factor: fctr -> fct (#71).
- Date columns now show sub-seconds if the `digits.secs` option is set (#74).
- Very wide tibbles now print faster (#85).
