Kannel development version 1.1.4 released

NEWS about Kannel: Open Source WAP and SMS Gateway version 1.1.4

This is a DEVELOPMENT version. It should be usable for experimentation
and testing, and is a release candidate for 1.2. Please do try it out
and report problems to [email protected] (the development mailing list)
or [email protected] (the bug tracking system).

NOTE: This is not an update to 1.0.  Updates to 1.0 will be numbered 1.0.x,
until we decide to release 1.2.  See the VERSION file for details.

Changes since version 1.1.3:

Security:

 * smsbox: X-Kannel-UDH headers in HTTP responses are no longer accepted,
   unless accept-x-kannel-headers is configured for the service.  This
   prevents possibly untrusted sites from setting strange UDH values.

 * Bugfix: An empty POST request from a client could crash the wapbox.

Compatibility breakers:

 * smsbox: HTTP responses with content-type application/octet-stream (or
   no content-type at all) will be sent as "octet data" instead of assumed
   to be text/plain.  This makes it possible to send for example ring tones
   in response to user messages.

 * smsbox: The "user" field is now required in all sendsms services.

 * Kannel now uses the same "data coding scheme" values in all SMSC
   protocols that use them.  It is now used only to set the alphabet,
   and leaves the message class alone.  This affects the Phone-as-SMSC,
   CIMD2, OIS, and SMPP modules.

 * Compiling Kannel now requires libxml 2.2.5 or later.

New features:

 * New sms-service type "posturl", which makes a POST request
   containing the message in the body and other information in X-Kannel-
   headers.  The sendsms interface also accepts POST requests in this format.
   Not documented yet.

 * Sendsms services also accept POST requests.

 * smsbox: X-Kannel-From and X-Kannel-To headers can be used in HTTP
   responses to set the sender and receiver numbers, if
   accept-x-kannel-headers is configured for the service.

 * New, improved module for UCP/EMI SMSC protocol, called "emi2".
   It will replace the emi and emi_ip modules in the future, but coexists
   with them in this release.

 * New configuration variable catch-all in sms-service configuration
   groups.  If this is set, the service will be used for all messages
   that match its keyword, instead of only messages that have the right
   number of words.  Useful for defining service-specific error replies.

 * Configuration variables such as "concatenation" can now be set to
   yes/no or true/false instead of just 0 or 1.

 * Kannel can be configured to store incoming SMS messages in a file
   until they have been processed, so that they can not be lost in a crash.

 * Improved portability to MacOS X.

 * SMPP SMSC module will send enquire_link packets at regular intervals.
   This is needed to stay connected with some SMSCs.

 * Significant improvements to the SMPP SMSC module.  It should now be
   ready for serious use.

 * Phone-as-SMSC module will retry a few times if sending a message fails.
   This works around many temporary problems.

Bugfixes:

 * Support libxml versions that install xml2-config instead of xml-config.

 * Several memory leaks fixed.

 * Fixed panic if faked-sender configuration variable is used in a sendsms
   service.

 * Sendsms replies now have no-cache headers to prevent proxies from
   trying to cache sendsms queries.

 * Some PDU encoding errors in the Phone-as-SMSC module were fixed.

 * CIMD2 SMSC module works around a bug in some SMSCs that could cause
   messages to be received multiple times.

 * HTTP module can (again) handle "100 Continue" responses from servers.

 * Lots of minor bugfixes.

Development news:

 * More work on WAP Push.

Known problems:

 * New POST-based interface for SMS is not documented.

 * The CIMD2 SMSC module can sometimes send multiple "alive" requests
   at a time, which breaks the protocol and confuses the SMSC.

 * Concatenated text messages don't work with all protocols.
