rlang 1.0.3

• Child errors may now have empty messages to enable this pattern:

  Error in `my_function()`:
  Caused by error in `their_function()`:
  ! Message.
  

• The rlib_bytes class now uses prettyunits to format bytes. The
  bytes are now represented with decimal prefixes instead of binary
  prefixes.

• Supplying a frame environment to the call argument of abort()
  now causes the corresponding function call in the backtrace to be
  highlighted.

  In addition, if you store the argument name of a failing input in
  the arg error field, the argument is also highlighted in the
  backtrace.

  Instead of:

  cli::cli_abort("{.arg {arg}} must be a foobar.", call = call)
  

  You can now write this to benefit from arg highlighting:

  cli::cli_abort("{.arg {arg}} must be a foobar.", arg = arg, call = call)
  

• abort(message = ) can now be a function. In this case, it is
  stored in the header field and acts as a cnd_header() method
  invoked when the message is displayed.

• New obj_type_oo() function in compat-obj-type.R (#1426).

• friendly_type_of() from compat-obj-type.R (formerly
  compat-friendly-type.R) is now obj_type_friendly().

• options(backtrace_on_error = "collapse") and print(trace, simplify = "collapse") are deprecated. They fall back to "none"
  with a warning.

• call_match() now better handles ... when dots_expand = FALSE.

• list2(!!!x) is now faster when x is a list. It is now returned
  as is instead of being duplicated into a new list.

• abort() gains a .trace_bottom argument to disambiguate from
  other .frame. This allows cli::cli_abort() to wrap abort() in
  such a way that .internal mentions the correct package to report
  the error in (#1386).

• The transpose() compat is now more consistent with purrr when
  inner names are not congruent (#1346).

• New reset_warning_verbosity() and reset_message_verbosity()
  functions. These reset the verbosity of messages signalled with
  warn() and inform() with the .frequency argument. This is
  useful for testing verbosity in your package (#1414).

• check_dots_empty() now allows trailing missing arguments (#1390).

• Calls to local functions that are not accessible through :: or
  ::: are now marked with (local) in backtraces (#1399).

• Error messages now mention indexed calls like foo$bar().

• New env_coalesce() function to copy bindings from one environment
  to another. Unlike approaches based on looping with [[<-,
  env_coalesce() preserves active and lazy bindings.

• Chaining errors at top-level (directly in the console instead of in
  a function) no longer fails (#1405).

• Warning style is propagated across parent errors in chained error
  messages (#1387).

• check_installed() now works within catch-all tryCatch(error = )
  expressions (#1402, tidyverse/ggplot2#4845).

• arg_match() and arg_match0() now mention the correct call in
  case of type error (#1388).

• abort() and inform() now print messages to stdout in RStudio
  panes (#1393).

• is_installed() now detects unsealed namespaces (#1378). This fixes
  inconsistent behaviour when run within user onLoad hooks.

• Source references in backtraces and last_error()/last_trace() instructions
  are now clickable in IDEs that support links (#1396).

• compat-cli.R now supports style_hyperlink().

• abort(.homonyms = "error") now throws the expected error (#1394).

• env_binding_are_active() no longer accidentally triggers active bindings
  (#1376).

• Fixed bug in quo_squash() with nested quosures containing the
  missing argument.
