CloudI (http://cloudi.org/) is a "universal integrator" using an Erlang core,
with its actor model, to pursue efficiency, fault-tolerance and scalability.
The CloudI API provides a minimal interface to communicate among actors that
are called services (long-lived processes), so programming language agnostic,
database agnostic, and messaging bus agnostic integration can occur.
CloudI currently integrates with the programming languages
Erlang, Elixir, C/C++, Java, Python, and Ruby, the databases PostgreSQL,
elasticsearch, Cassandra, MySQL, couchdb, memcached, riak, and tokyotyrant,
the messaging bus ZeroMQ, websockets, and the internal CloudI service bus.
HTTP is supported with both cowboy and elli integration.

Thanks to Irina Guberman for the Cassandra CQL integration and everyone for the
various feedback/issues/bugs that have been reported.
The details for this release are below:

   * backwards compatibility difference:
     * Some minor functions were deprecated in the cloudi_service module and the
       source code was moved to separate modules
       (cloudi_environment, cloudi_service_name, cloudi_request,
        cloudi_request_info, cloudi_key_value)
     * The CloudI Service API had some functions renamed with the older name
       deprecated (loglevel_set became logging_level_set and
       log_redirect became logging_redirect_set)
     * In version 1.4.0 of CloudI the cloudi_service behaviour will have a
       Timeout parameter in both the cloudi_service_init callback and the
       cloudi_service_terminate callback (if you want to start using it now,
       make sure cloudi_core is compiled with the CLOUDI_SERVICE_NEW define,
       a CLOUDI_SERVICE_OLD macro will exist in version 1.4.0 to avoid the
       change so older services can run without modification)
     * cloudi_service_api_requests now provides simpler URL paths for the
       CloudI Service API (while continuing to support the older URL paths)
(https://github.com/CloudI/CloudI/tree/master/src/service_api#api)
     * Python 3 usage requires that the request_info, request,
       response_info, and response data be bytes
   * Elixir is now supported officially and has an example at
https://github.com/CloudI/CloudI/tree/master/examples/Elixir.HelloWorld1
   * Python 3 is now supported by the Python CloudI API
     (both the cloudi module and the cloudi_c module)
   * queue_size is a service configuration option added so any service may
     limit their incoming service request queue by an amount of memory (in kB)
     (queue_limit provides a count limit and both can be used together)
   * Support for Aspects (from AOP, Aspect-Oriented Programming) were added
     as service configuration options
     (aspects_init_after, aspects_request_before, aspects_request_after,
      aspects_info_before, aspects_info_after, aspects_terminate_before)
     so a series of Erlang (or Elixir) functions can be executed
     before and/or after a cloudi_service behaviour function is executed and
     possibly modify the service state (for both internal and external services)
(http://cloudi.org/api.html#2_services_add_config_opts_aspects_init_after)
   * Service initialization and termination are now enforced to be synchronous
     as described here (for both internal and external services):
     * initialization must be completed before the next service in a sequence
       (including the configuration file list of services) is started
     * termination causes the service to stop and terminate within the
       termination timeout defined by slightly less than MaxT/MaxR
       (clamped to [1..60] seconds)
   * lager formatters and lager backends are now supported as described at
     http://cloudi.org/api.html#2_logging_formatters_set
   * cassandra CQL support was added by Irina Guberman
     (as cloudi_service_db_cassandra_cql)
   * Added Riak support with the cloudi_service_db_riak service
   * Added OAuth v1 support with the cloudi_service_db_oauth1 service
   * The cloudi_service_db_pgsql service now supports
     3 separate postgres drivers and provides common output for all 3
     (wg epgsql, semiocast pgsql, and epgsql epgsql (new))
   * The cloudi_service_db_mysql service was updated to use the
     Eonblast fork of emysql and supports the same common output as
     cloudi_service_db_pgsql
   * cloudi_service_http_cowboy was updated to use Cowboy 1.0.0
   * cloudi_service_filesystem now supports write operations as append/insert or
     truncate with byte ranges that can also be used to read
   * Many bugfixes, other additions, and documentation improvements
     (see the ChangeLog for more detail)

Please mention any problems, issues, or ideas!
Thanks,
Michael
