- * The function `print_with_color` can now take a color represented by an integer between 0 and 255 inclusive as its first argument ([#18473]).
- For a number to color mapping please refer to [this chart](https://upload.wikimedia.org/wikipedia/en/1/15/Xterm_256color_chart.svg).
- It is also possible to use numbers as colors in environment variables that customizes colors in the REPL.
- For example, to get orange warning messages, simply set `ENV["JULIA_WARN_COLOR"] = 208`.
- Please note that not all terminals support 256 colors.

- * The function `print_with_color` no longer prints text in bold by default ([#18628]).
- Instead, the function now take a keyword argument `bold::Bool` which determines whether to print in bold or not.
- On some terminals, printing a color in non bold results in slightly darker colors being printed than when printing in bold.
- Therefore, light versions of the colors are now supported.
- For the available colors see the help entry on `print_with_color`.
-
- * The default color for info messages has been changed from blue to cyan and for warning messages from red to yellow.
- This can be changed back to the original colors by setting the environment variables `JULIA_INFO_COLOR` to `"blue"` and `JULIA_WARN_COLOR` to `"red"`.
- One way of doing this is by adding for example `ENV["JULIA_INFO_COLOR"] = :blue` and `ENV["JULIA_WARN_COLOR"] = :red` to the `.juliarc.jl` file.
