2.2.24
  * sandbox directories must be world executable (server runs as "nobody")

2.2.23
  * do not allow external mails to the steam group (to prevent heavy server
    load when spam is sent to the steam group)
  * add service user to admin group (this is required for search services
    which need read access to all objects on the server...)
  * pass the service user name and password to the services via environment
    variables and no longer via command line parameters
  * ldap bugfix (users and groups could be mixed up on lookup when certain
    attributes in ldap matched)


2.2.21
* bugfixes in security cache
* cleanup in spm module

2.2.19

  /etc/steam/persistence.cfg if you have an old version from 2.2.18)

2.2.18
* introduced persistence.cfg (preliminary version)

2.2.14
* fixed event problems

2.2.13
* Changed Config library back to the old behavior of not interpreting
  "yes", "true", "on", "no", "false", "off" as 0/1 int values. This
  caused problems because this behavior is usually unexpected.
  There is a new convenience function bool_value() in the Config lib.
