| .. versionadded:: 3.21 |
| |
| The :command:`list` command now detects invalid indices. |
| |
| Prior to CMake version 3.21, the :command:`list` command's ``GET``, |
| ``INSERT``, ``SUBLIST``, and ``REMOVE_AT`` subcommands did not detect invalid |
| index arguments. |
| |
| The ``OLD`` behavior of this policy is for invalid indices to be treated as |
| their integer value (if any) at the start of the string. For example, |
| ``2good4you`` is a ``2`` and ``not_an_integer`` is a ``0``. The ``NEW`` |
| behavior is for invalid indices to trigger an error. |
