2.9 Obsolete Options and/or Features
====================================

This minor node describes features and/or command-line options from
previous releases of 'gawk' that either are not available in the current
version or are still supported but deprecated (meaning that they will
_not_ be in a future release).

   The arbitrary precision arithmetic feature is deprecated as of 'gawk'
version 5.2.  Use of '-M'/'--bignum' produces a warning message.  The
feature will be removed in the release of 2024.
