 * Added on-the-fly shutdown and re-start for specific smsc-ids via the
   administrative HTTP interface URIs 'stop-smsc' and 'start-smsc'.

 * Added traffic statistics of inbound and output SMS on the status page.

 * Added 'interface-version' config directive for SMPP module.

 * Added timing configuration directives for SMPP module to specify 
   reconnect delays and timeout values.

 * Added alternative DCS support for SMPP module to define alternative DCS
   value via sendsms's alt-dcs flag.

 * Added support for XML POSTs of SMS messages on the basis of the IETF
   draft http://search.ietf.org/internet-drafts/draft-koponen-sms-xml-03.txt.

 * Added transceiver mode for SMPP links.

 * Added wapbox directive 'smart-errors' for smarter WSP error messages to
   the handset device.

 * Added wapbox directive 'force-sar' for forced processing of segmentation
   and reassembly (WTP-SAR) packages.

Bugfixes:

 * Fixed compiler warning for gcc 3.x for compiler macros.

 * Fixed a couple of memory leaks in various modules.

 * Improved the output of the status page and fixed the status condition
   if an SMPP link is only used as receiver.

 * Fixed validity issues in the SMPP module.

 * Fixed a possible segv bug in SSL connection opening call.

 * Fixed handling of application ids in the PPG module.

 * Implemented a queue limit for outbound messages. This should hold up the
   situation that there are infinitely more messages injected to the queue
   then there are outflowing to the SMSC connections.

 * Further improvements in the AT2 module.

 * Fixed some MySQL related problems while processing DLRs to databases.


Changes since version 1.1.6:

Compatibility breakers:

 * GET method variable 'phonenumber' will be replaced by 'to' for the 
   sendota HTTP interface. Currently we run both, to allow users to 
   switch seamlessly.

New features:

 * sendota HTTP interface requests can be send in POST method mode
   containing special X-Kannel HTTP headers for the control information
   and the OTA XML document as body content.


Changes since version 1.1.5:

Compatibility breakers:

 * Major restructuring of the AT2 module has been done. 
   See the ChangeLog for more details.
 
New features:

 * PPG module has been introduced and works for both IPv4 and SMS based 
   bearers. Supported document types are SL and SI. The PPG is an essential
   item of the WAP Push architecture.

 * WTLS support has been included, but yet not finished. 
   Development in this area is still needed.

 * Flash SMS support added.
   Messages that arrive at mobile terminals are displayed directly to the
   user interface and usually they can not be saved to the inbox.

 * 3G Lab contributed the XML files for their Alligata.
 
 * Added "keepalive" feature for EMI2 module.

 * MWI (message waiting indicator) message support added.
   These messages do cause the mobile terminal to indicate special events
   on the user interface, i.e. showing that a new E-Mail has arrived.

 * AT2 now supports Siemens TC35

 * Added DLR (delivery report) support for SMSC modules.
   Delivery reports are returned by SMSCs and can trigger a defined URL in 
   order to inform the pushing application of a successful transmission of
   the message. URLs can be set on a per-message request basis and hence 
   semantics of the message ID is kept by the requesting application.

 * AT2 now support autodetection of modem devices.

 * HTTP basic authentication can be used now for sms-service groups.
   This allows SMS services to access HTTP resources that need explicit
   user authentication using the HTTP basic authentication scheme (RFC 2617).

 * EMI2 windowing control has been added.
   
 * DLRs may be stored to external storage.
   Using the --with-dlr configure flag external storage spaces may be used 
   for the DLRs. This is useful in cases you take your boxes down and 
   do not want to loose all pending DLR messages. 
   Currently MySQL is supported as external storage.
 
 * SSL-enabled HTTP servers are now available for any HTTP interface.
   Users may rely now on secured HTTPS scheme communication between HTTP
   clients and Kannel's HTTP servers. This is used for the sendsms and the
   administration HTTP interface.

 * Cygwin platform is now supported out-of-the-box without additional pthreads
   libraries from 1.3.9.

 * WAP OTA (over-the-air) has been improved.
   OTA settings and bookmarks may be send via SMS bearer to capable mobile
   terminals. Pre-defined sets from the configuration may be send or 
   individual sets using a GET request parameter. 
   This will change to allow POST of the OTA XML document.

 * Several new phones are supported for the AT2 module.
   See the doc/modems.conf file for their definitions.

 * New sendsms HTTP interface field 'account' has been introduced.
   This is mainly for accounting purposes.

 * SSL-enabled inter-box TCP communication can be used.
   In case boxes are running on different machines in different unreliable
   networks this may be used to secure the TCP connection between them, i.e.
   smsbox talking to a remote bearerbox and communication is SSL-enabled.

 * URIs for the HTTP interfaces configurable.
   The HTTP interface default URIs for the sendsms and sendota functions may 
   be defined in the configuration to individual URIs.
   
 * Added SMSC interface implementation to Sonera ContentGateway. 

 * Solaris packaging added.

 * Added 'exec' translation type to sms-service.
   This allows to execute arbitrary external code and pass the output as 
   reply to the message sender.

 * Include within configuration files added.
   This makes 'include = "foobar.conf"' possible and hence segmenting the groups
   to their own config files to make the setup more clean.

 * Improved HTTP SMSC behaviour.

 * SIM buffering for AT2 has been included.
   This is a fail-safe mechanism to handle messages that pass the regular line
   of processing to the SIM card.

Bugfixes:

 * Various fixes in all major SMSC modules.

 * Fixed bugs in text concatenation.

 * Fixed make process bug for Solaris 2.6

 * Various memory leaks have been fixed.

 * Fixed default DocBook detection for FreeBSD platform.

 * Fixed forced-smsc bug for sendota HTTP interface.

 * Fixed issues to support Linux on PowerPC and S390 again.

Development news:

 * WTLS is the next major challenge.
   At least --with-wtls=openssl configure leads to a clean make process.
   3ui's kwtls package seems to be good enough as sample for the missing
   WTLS parts.

 * Added general MySQL connection support.
   This may be extended to have several groups reside in corresponding MySQL
   tables and hence operation of highly dynamical environments gets easier, 
   because there is no need to restart or -HUP the boxes.
   

Changes since version 1.1.4:

Compatibility breakers:

 * sendsms service now uses the HTTP status code in replies, instead of
   always using 200.  Valid requests get 202 (Accepted), invalid requests
   get an error code.

New features:

 * fakewap is better at testing high loads.

 * Added sender-prefix configuration variable for CIMD2.

 * A new sms-service escape sequence, %i, which expands to the smsc-id
   of the message.

 * Added a status.xml service to the administration interface.

Bugfixes:

 * Minor bugfix to emi2.

 * Fixed handling of accept-x-kannel-headers and assume-plain-text
   configuration fields.

 * Phone-as-SMSC driver can handle text messages with UDH.

 * Fixed a rare case that could cause a deadlock between the bearerbox
   and smsbox.

 * Fixed a bug that prevented having many smsc configuration blocks.

 * HTTP: Correctly handle redirections to invalid URLs.

 * Don't panic if there is no "default" sms-service.

Development news:

 * Beginnings of https support.  Not secure yet.


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.
