It has always been the intention to make SAM a messaging protocol/
server neutral API and allow the addition of support for multiple
messaging infrastructures. Version 1.1.0 makes this a reality by
making it easy to add support for other protocols and messaging
systems either as C code PHP extensions or as simple PHP scripts. The
existing XMS support C extension has been restructured to be an
example of extending SAM using C while a new PHP implementation of the
MQTT protocol has also been added. SAM can now be configured through
php.ini entries to control which protocol implementation deals with
which SAM API requests. The API itself remains unchanged.
Documentation has been updated to reflect the new features and
installation steps and is available from the project website (http://
project-sam.awardspace.com) as are Windows binaries for PHP 5.0.5,
5.1.4 and 5.1.6.
