  • 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.
