+# ## Changelog
+#
+# 2023-05-01:
+# - `obj_type_friendly()` now only displays the first class of S3 objects.
+#
+# 2023-03-30:
+# - `stop_input_type()` now handles `I()` input literally in `arg`.
+#
+# 2022-10-04:
+# - `obj_type_friendly(value = TRUE)` now shows numeric scalars
+#   literally.
+# - `stop_friendly_type()` now takes `show_value`, passed to
+#   `obj_type_friendly()` as the `value` argument.
+#
+# 2022-10-03:
+# - Added `allow_na` and `allow_null` arguments.
+# - `NULL` is now backticked.
+# - Better friendly type for infinities and `NaN`.
+#
+# 2022-09-16:
+# - Unprefixed usage of rlang functions with `rlang::` to
+#   avoid onLoad issues when called from rlang (#1482).
+#
+# 2022-08-11:
+# - Prefixed usage of rlang functions with `rlang::`.
+#
+# 2022-06-22:
+# - `friendly_type_of()` is now `obj_type_friendly()`.
+# - Added `obj_type_oo()`.
+#
+# 2021-12-20:
+# - Added support for scalar values and empty vectors.
+# - Added `stop_input_type()`
+#
+# 2021-06-30:
+# - Added support for missing arguments.
+#
+# 2021-04-19:
+# - Added support for matrices and arrays (#141).
+# - Added documentation.
+# - Added changelog.
