Just to clear this little bit of particularly unconstructive FUD from
the air , no they haven't changed NISAM but created a new format :-

Upgrading from a 3.22 version to 3.23
-------------------------------------

*MySQL* 3.23 supports tables of the new `MyISAM' type and the old
`NISAM' type. You don't have to convert your old tables to use these
with 3.23. By default, all new tables will be created with type
`MyISAM' (unless you start `mysqld' with the
`--default-table-type=isam' option. You can change an `ISAM' table to a
`MyISAM' table with `ALTER TABLE' or the Perl script
`mysql_convert_table_format'.
