The most significant changes with this release compared to apache up to
Mandriva Linux 2006.0, 2007.0, 2007.1, 2008.0 and 2008.1

 o mod_ssl has support for distcache, apr_memcache and SNI per default.
 o The SSL certificates and directories has been moved to the new /etc/pki
   directory structure.
 o The SSL default vhost config file has been moved from
   /etc/httpd/modules.d/41_mod_ssl.default-vhost.conf to
   /etc/httpd/conf/vhosts.d/01_default_ssl_vhost.conf
 o The new htcacheclean subpackage will monitor and clean the mod_proxy
   (mod_disk_cache) directories at given intervals in a daemonized fashion.
   You can tune this in the /etc/sysconfig/htcacheclean configuration file.
 o There are three new experimental MPM's, the ITK, peruser and event MPM's.
   Use these with caution because of their experimental status. The packages
   are named:
   - apache-mpm-event
   - apache-mpm-itk
   - apache-mpm-peruser

Please read the following files for more in-depth information about the changes
in apache 2.2; upgrading.txt and new_features_2_2.txt

The best practise is to read the apache manual before sending in bugreports,
please install apache-doc like so:

urpmi apache-doc

and then read the somewhat localized apache manual online at:

http://localhost/manual/

Thanks in advance.
