cli_abort() has been updated to work nicely with rlang 1.0. The default call and backtrace soft-truncation are set to .envir (which itself is set to the immediate caller of cli_abort() by default).
Line formatting now happens lazily at display time via rlang::cnd_message() (which is called by the conditionMessage() method for rlang errors).
New hash_sha256() function to calculate SHA-256 hashes. New hash_raw_*(), hash_obj_*() and hash_file_*() functions to calculate various hashes of raw vectors, R objects and files.
You can use the new cli.default_num_colors option to set the default number of ANSI colors, only if ANSI support is otherwise detected. See the details in the manual of num_ansi_colors().

boxx() now correctly calculates the width of the box for non-ASCII characters.

New style_hyperlink() function to add hyperlinks, on terminals that support them.
cli_format_method() now works properly in knitr, and other environments that catch message conditions (#159).
ANSI strings created by col_*, bg_* and style_* now also add the character class to the result. This fixes issues with code that expect character objects.

make_spinner() clears the line properly now (@tzakharko, #164).
Semantic cli functions now automatically replace Unicode non-breaking space characters (\u00a0) with regular space characters, right before output. They are still used to calculate the line breaks, but not outputted (#161).

See the “Building a semantic CLI” article on the package web site: https://cli.r-lib.org
is_dynamic_tty(), setting R_CLI_DYNAMIC="FALSE" now properly turns dynamic tty off (#70).cli has now functions to add ANSI styles to text.

New is_dynamic_tty() function detects if \r should be used for a stream (#62).
