The PostfixAdmin package in Leap 15.0 (and also Tumbleweed) comes with a
changed directory layout, which also brings a backwards-incompatible change
(PostfixAdmin will no longer read the config files at the old location).

This especially means users will have to move their config.local.php to
/etc/postfixadmin and (if they did changes to config.inc.php) migrate these
changes, ideally to /etc/postfixadmin/config.local.php.

Users will also need to enable or add the /postfixadmin alias in the apache
config.


Can you please add [something like] the following text to the "Upgrade" section
of the release notes?

PostfixAdmin: Changed directory layout

PostfixAdmin 3.2 comes with a changed directory layout. Instead of having
everything in /srv/www/htdocs/postfixadmin/,
- the config files (config.inc.php and config.local.php) are now in 
  /etc/postfixadmin/. (It's recommended to keep config.inc.php unmodified,
  and to add config changes to config.local.php.)
- the PHP code moved to /usr/share/postfixadmin/
- the smarty cache moved to /var/cache/postfixadmin/

Note that /srv/www/htdocs/postfixadmin/config.*.php will _not_ be moved to
/etc/postfixadmin/ automatically on upgrades, so you'll have to migrate your
config changes manually.

Also note that the /postfixadmin alias is _not_ enabled in Apache by default. 

To enable the /postfixadmin alias, run
    a2enflag POSTFIXADMIN && rcapache2 restart
This will make /postfixadmin available on all virtual hosts.

If you want to have the /postfixadmin alias only on a specific virtual host,
add the alias to the config of that vhost.

-------------------------------------------------------------------------

For the Apache config, you can replace the text starting at "To enable..." with
a reference to the comments in /etc/apache2/conf.d/postfixadmin if you think
the text is too long.

Also, feel free to drop the "(It's recommended ...)" sentence if you think it
makes the text too long.
