* Added an extended version of the function mrcp_session_create(), which takes an external memory
pool as an input argument by optionally taking ownership of the provided pool.
* Added support for NTATAG_TIMER_C, which is disabled by default and can be specified via the
client API or the configuration file unimrcpclient.xml.
MRCP server library
* Moved the function mrcp_session_answer_create() to a common place, since this function is used
not only by the server, but also by a new proxy application.
* Added a new helper macro for the plugins providing support for the use a custom log source.
MRCPv2 transport library
* Added a new function mrcp_control_offer_copy(), which is used by the proxy application to copy
an offer received from the client in order to amend and send it over to the server.

mechanism by MRCP clients.
Changes for UniMRCP-1.3.0
APR-toolkit library
* Allow timers to be re-set. The ongoing timer, if any, will be implicitly stopped.
* Added an optional timer support to the consumer task. This change requires the UniMRCP-deps 1.3.0 or above.
* Slightly modified processing of start and termination requests in the apt_task interface.
* Release task message, if the method signal() fails.
* Added new methods to the apt_task interface to take a task offline: apt_task_offline()

* Compose native file paths by using APR_FILEPATH_NATIVE flag.
* Enhanced apt_dir_layout interface to allow creation and loading of bare and extended layouts.
* Made apt_dir_layout_t structure opaque. This change may incur insignificant changes in user applications.
* While parsing a header field spanning multiple lines, check the return value of
apt_text_line_read() first, and only then add the read line to the array.
* Check the return value of apt_text_field_read() and only then, based on the result,
use either apt_string_copy() or apt_string_reset().
* Fixed a possible integer overflow in the poller and consumer tasks.
MPF library
* Fixed a possible overflowed array index read (aka out-of-bound read) reported by Coverity.
* Use memmove() instead of strcpy() for overlapping buffers.
* While making calculations in mpf_codec_descriptor, cast to size_t first and only then multiply.
MRCP common library
* In mrcp_header_field_add(), do not try to add the same header field twice.
The second attempt would have failed anyway, though.
MRCP client library
* Use apr_ring instead of apt_obj_list for MRCPv2 connections.
* Use apr_filepath_merge() to compose native file paths while loading the client stack.
* Append a UniMRCP version string to the SIP user agent field.
* For SIP message logging, if enabled, compose a path relative to the log directory by default.
Alternatively, a full path can be specified.
* Fixed a potential NULL pointer dereference on processing of MPF messages.
* Fixed a possible explicit NULL pointer dereference in mrcp_client_profile_create_ex().
* Fixed a possible NULL pointer dereference which may occur when an invalid XML document name is
specified in the configuration file.
* Check the return value of apt_task_msg_acquire().
* Separated declarations of MRCP client and server profiles.
MRCP server library
* Use apr_ring instead of apt_obj_list for MRCPv2 connections.
* Use a connection specific pool for apr_socket_accept(). This makes memory allocation for accepted
sockets more predictable and prevents possible indefinite use of the shared pool.
* Use apr_hash to hold pending control channels. Before, mrcp_connection was used
as a temporary container.
* Append a UniMRCP version string to the SIP user agent field.
* For SIP message logging, if enabled, compose a path relative to the log directory by default.
Alternatively, a full path can be specified.
* Fixed a potential NULL pointer dereference on processing of MPF messages.
* Fixed a possible NULL pointer dereference which may occur when an invalid XML document name is
specified in the configuration file.
* If channel->resource is a NULL pointer, do not dereference it while composing a log statement.
* Separated declarations of MRCP client and server profiles.
RTSP library
* Use apr_ring to hold a list of RTSP connections. This change allows to get rid of a sub-pool
used for the connection list.
Sofia-SIP module (MRCPv2 agent)
* Let Sofia-SIP implicitly set the Contact header included in the transport parameter, when needed.
This change fixes an interoperability problem with Avaya using SIP over TCP.
* Do not uselessly check sip_contact->m_url against a NULL pointer,
since m_url is actually an array but not a pointer.
* In case of redirection (SIP 3xx responses), compose the To header based on the Contact using
the API of Sofia-SIP.
* Pass all the parameters to nua_create() and do not unnecessarily call nua_set_params().
Miscellaneous
* Remove automake generated build/compile script on maintainer-clean.
* Use AM_CPPFLAGS instead of deprecated INCLUDES.
* Use subdir-objects with AM_INIT_AUTOMAKE to prevent a bunch of warning messages encountered
with automake 1.14.
* Fixed support for out of tree build.
* Use GNU standard 'sysconfdir' variable instead of custom 'confdir'.
* Use APR_ENABLE_LAYOUT macro for pre-defined installation paths layouts.
* Separated var and data directories. The var directory is supposed to hold files being created
and modified on run-time.
* Enhanced UNIMRCP_CHECK_SOFIA m4 macro to look not only for Sofia-SIP installed prefix and
source/build tree but also for the full path to Sofia-SIP pkg-config file.
* Added a new optional command-line argument '--dir-layout' to the applications unimrcpserver,
unimrcpclient, and umc. The argument, if specified, allows to load a custom directories layout
from the provided configuration file.
* Use AM_PROG_CC_C_O macro in configure.ac, since automake 1.9 fails to generate Makefile.in
when/if the option subdir-objects is specified with AM_INIT_AUTOMAKE but AM_PROG_CC_C_O is not used.
* Added new configure enable/disable options to control build of libraries and applications
located in the platforms directory.
* Added uni_revision.h file to the repository. Removed utility project svnrev which was supposed
to generate uni_revision.h.
* Added a new #define UNI_REVISION_AT_LEAST(rev) which allows to check at compile time
that the revision base number is at least a certain level.

Changes for UniMRCP-1.1.0
APR-toolkit library
* The function apt_log_file_open() makes a copy of dir_path and file_name variables passed from a user application.
* Applied a patch to the apt_log routine which allows the log file to be appended instead of being overwritten. The patch was submitted by Dani. Thanks.
* Added a new parameter to the function apt_log_file_open() which specifies whether the log file should be appended or overwritten.
* Fixed the formatting of float values in the header fields. Applied a patch submitted by Randy (Issue-108). Thanks.
* Fixed apt_log_output_mode_check() which returned TRUE if any mode was enabled or checked regardless their correspondence. Thanks Vali.

MPF library
* Tweaked DTMF detector's energy thresholds to eliminate false positives during in-band (from audio) DTMF detection. Thanks Vali.
* Took into consideration the RTP marker in order to re-sync the jitter buffer on a new talkspurt. Audio data loss could be experienced in the RTP receiver in case of consecutive SPEAK (for client) or RECOGNIZE (for server) requests.
* Instead of discarding a non-aligned RTP packet, adjust the timestamp and write available frames to the jitter buffer (Issue-122).
* Added support for the adaptive jitter buffer. Applied a reworked patch submitted by Erik. Thanks.
* Enhanced the detection of a new RTP talkspurt by implicitly setting the RTP marker if a gap between two RTP packets is more than the specified threshold (INTER_TALSKPUSRT_GAP = 1000 msec).
* Allow the initial playout delay in the jitter buffer to be set to 0.
* Implemented a time skew detection algorithm for RTP streams. The detection can be enabled and used for both the adaptive and static jitter buffer.

* Added support for custom MRCP header fields.
* Added support for speaker verification and identification resource.
* Added missing recognizer methods used for voice enrollment and interpretation.
* Updated the state machine of the recognizer resource to take into consideration requests, responses and events used for interpretation.
* Enhanced helper functions which operate on the MRCP header to properly set, get and inherit header fields (Issue-110).
MRCP client library
* Added support for SIP redirection with 300 Multiple Choices used by the Nuance Resource Manager.
* Added support for feature-tags set in the SIP Accept-Contact header field in an outgoing SIP INVITE message sent to the Nuance Resource Manager.
* Added a new accessor function to the client API to get an audio stream associated with the specified channel. The function name is mrcp_application_audio_stream_get().
* Added the ability to retrieve an external object associated with the MRCP session through the log handler (apt_log_ext_handler_f).
* Fixed the processing of a response to the SIP OPTIONS request used for resource discovery (Issue-112).
* Added a new constructor function unimrcp_client_create2() which allows to pass the client XML configuration not by a file, but rather by a string parameter. Thanks Vali.

* When originating an offer from the client, take into account capabilities of an audio stream created by the client user application.
* Added a new function to the client API to retrieve a SIP/RTSP response code received from the server (Issue-90). The support is incomplete.
MRCP server library
* Fixed an interoperability issue with AVP. The mid attribute is not required when the SDP contains only one m-line.
* Fixed the build of C++ MRCP plugins for platforms other than Win32. Thanks Vali.
* Added the ability to take and use parameters set by the plugin in a response to the GET-PARAMS request. Thanks Vali.
Sofia-SIP module
* Took out unused tags (variables) to compile with Sofia-SIP 1.12.11.
* Added support for Sofia-SIP's TPTAG_LOG() and TPTAG_DUMP() tags which can be enabled from the client and server configuration to print out and/or dump SIP messages.
PocketSphinx plugin
* In the PocketSphinx plugin, instead of using one common timeout for detection of speech activity and inactivity, use two different timeouts: one for activity and the other for inactivity detection.
* In the recognition results sent from the PocketSphinx plugin, set both <instance> and <input> elements.
* Fixed a race condition in the PocketSphinx plugin which caused the server to crash.
* Fixed the use of recognition timer in the PocketSphinx plugin.
* Set an MRCP version specific completion cause in the PocketSphinx plugin.
UniMRCP server application

* Added support for Visual Studio 2010.
* Modified the MPF test application to read a raw PCM data from one file, transmit it over RTP, and write the data back to another file.
* Set the libtool parameters link_all_deplibs and link_all_deplibs_CXX to "yes" by default, with an option to disable them (--disable-interlib-deps), if ever needed. This fixes a link error on recent Debian/Ubuntu distributions.
* Modified the apr.m4 and apu.m4 macros to use '--link-ld' instead of '--link-libtool --libs' for the APR library dependencies. This addresses the problem with a wrong -L path to the expat library.
* Set prerequisite version for autoconf to 2.59.
* Added a checking for pkg-config to the configure script.
* Added a new option (-v or --version) to the unimrcpserver as well as the sample umc and unimrcpclient applications.
