Kannel release 0.12.3 - update to stable release

NEWS about Kannel: Open Source WAP and SMS Gateway version 0.12.3

This is a STABLE version. We will maintain it and make bugfix
releases until the next stable version is released.

We plan to rename this release to version 1.0 on December 18th
if there are no serious problems with it.

Please try it out and report problems to [email protected] (the  
development mailing list) or [email protected] (the bug tracking system).

Changes since version 0.12.2:

Security:

 * Removed the "www" example service from the sample configuration 
   file smskannel.conf.  It is a security problem in some setups, and
   people seem not to remove it from production installations.
   (Impact was: possible use of intraweb services by outsiders)

 * Made bearerbox not crash if a connection from a denied IP is tried.
   (Impact was: denial of service)

New features:

 * Improved userguide.

Bugfixes:

 * Bearerbox detection of inactive SMSCs is less trigger-happy. 
   This greatly improves throughput if the roundtrip to the SMSC is
   slower than 10 milliseconds.

 * SMPP driver handles unexpected data codings without crashing.
   Also fixed memory leak.

 * Detect libxml 2.2.10 and above as part of the 2.2.x series.

 * In HTML to SMS conversion, parse entities like Ӓ correctly.

 * Support WAP phones that claim to support an unlimited deck size.
