To give one example, you see the following warning:
postfix/trivial-rewrite[14777]: using backwards-compatible
default setting append_dot_mydomain=yes to rewrite
"localhost" to "localhost.example.com"; please add
"localhost" to mydestination or other address class
because:
1) the compatibility_level is not set to 2,
2) AND you haven't explicitly specified append_dot_mydomain,
3) AND the append_dot_mydomain built-in default setting has changed,
4) AND your system appears to depend the old setting.
Ditto for any of the other parameters whose built-in default setting
has changed, and whose old default setting appears to be depended on.

You see the above warning because your system appears to rely on
the old default setting, so you might want to explicitly set that
parameter before setting compatibility_level=2.
