    - <b>Detailed list of changes:</b>
            - Applications:
                    - simul-landmarks:
                            - New parameter "show_in_3d" to display a 3D view with the complete simulated robot path and landmarks.
                            - It can now simulate random walks of a robot in 6D, not only over a 2D plane as in previous versions.
                            - Generated rawlogs are gz-compressed.
                    - RawlogViewer:
                            - Much more efficient operations of cutting a rawlog (removing a part, keeping a part only), via a new method mrpt::CRawlog::remove() for ranges of indices.
                            - The program can now export all the images from a given camera as an AVI file (or two, for stereo cameras).
                            - New menu option to regenerate the odometry timestamps of very old datasets (<=2007).
                    - icp-slam:
                            - The program 'icp-slam', and mrpt::slam::CMetricMapBuilderICP, are now capable of handling two kinds of rawlogs: based on CSensoryFrame's (as usual), and the newest only containing CObservation's.
                            - New parameters to set a minimum distance between pose correction with ICP, for faster execution.
                    - kf-slam:
                            - Now has a much more rich live visualization as a 3D view. See http://www.mrpt.org/Application:kf-slam
                    - ICP and RBPF SLAM now have a new option to always insert any kind of CObservation-derived class. See mrpt::slam::CMetricMapBuilder::TOptions::alwaysInsertByClass

                    - Implementation of the observer/observable design pattern in the classes: mrpt::utils::CObservable & mrpt::utils::CObserver . See also the example "observer_pattern".
                    - Usage of the observer/observable design to dispatch events in GUI windows. See mrpt::gui::CBaseGUIWindow.
                    - Usage of the observer/observable design to enable anyone to subscribe to changes in metric maps. See mrpt::slam::mrptEventMetricMapInsert,                    - New set of classes to represent 6D poses using 3D translation + a quaternion for rotation:
                            - mrpt::poses::CPose3DQuat  - which can be transparently converted to/from mrpt::poses::CPose3D
                            - mrpt::poses::CPose3DQuatPDF

                    - New thread-safe template queue: mrpt::utils::CThreadSafeQueue, which is a generalization of the previous mrpt::utils::CMessageQueue.
                    - New hardware driver: mrpt::hwdriver::CBoardIR for a MAPIR custom I/O board for infrared sensors.
            - Improved classes:
                    - mrpt::bayes::CKalmanFilterCapable now has a new parameter (debug_verify_analytic_jacobians) to automatically verify the user-providen Jacobians vs. numerical ones.

                    - New serialization format of CPose3D, which saves about a 5% in (uncompressed) rawlog file sizes.
                    - Pose composition operator += added to mrpt::poses::CPosePDFGaussian, since it was missing there, but existing in the 3D version mrpt::poses::CPose3DPDFGaussian.
                    - Lightweight geometry structs TPose* & TPoint* now also have method asString() and fromString().

    - <b>BUG FIXES:</b>
            - mrpt::utils::CConfigFileBase didn't always remove extra leading and trailing whitespaces in read_string().
            - Initial size of the window was ignored in mrpt::gui::CDisplayWindow3D.
            - Error returning 2x1 size() in dynamic matrices, since there was only one static member shared by all matrices.
            - Swapped red-blue channels in mrpt::gui::wxImage2MRPTImage (Closes <a href="http://www.mrpt.org/node/70" >this issue</a>).
            - mrpt::poses::CPose3D undefined values when initializing from a "-" operator, due to bug in mrpt::math::homogeneousMatrixInverse().
            - mrpt::math::CHistogram::getBinRatio() and hence mrpt::math::histogram when do_normalization=true, always returned zero.
            - Fixed crash in rawlog-grabber when grabbing from a (non-stereo) camera and enabling preview (Closes <a href="https://sourceforge.net/tracker/?func=detail&aid=2988657&group_id=205280&atid=993006" >SF #2988657 </a>).
            - When grabbing images with mrpt::hwdrivers::CCameraSensor and decimation is enabled in mrpt::hwdrivers::CGenericSensor, all the images were saved to disk. It's been fixed so only the decimated ones are saved.
            - Fixed direction errors in the computation of 3D rays of OpenGL viewports for perspective projection. See mrpt::opengl::COpenGLViewport::get3DRayForPixelCoord()
            - RawLogViewer: When loading gz-compressed rawlogs, the "Loading" dialog may close too early.
            - fixed compilation with GCC < 4.4.1 - thanks to zhangbo (张波) for testing.
            - mrpt::opengl::CPointCloud: When color_from_Z is enabled, sometimes the colors switched when the range in Z was very close to 0.
            - rawlog-grabber: Parameter SF_max_time_span is now observed BEFORE inserting observations in sensory frames, thus the time span limit is strictly respected now.
            - More robust handling of strings with \ r \ n chars in matrixes fromMatlabFormat().
            - Fixed wrong results with mrpt::math::mean() and other functions when applied to vectors of integers (By Edu).
            - Fixed mrpt::system::tokenize's wrong behavior with GCC.

  - <b>IMPORTANT CHANGES</b>:
          - All classes reorganized into a new set of namespaces. Existing user-code out of MRPT will not compile, though changes typically imply just changing the names of the included files and adding some "using namespace XXX;" lines.
          - Better support of user applications using CMake command "FIND_PACKAGE( MRPT REQUIRED )". Refer to: http://www.mrpt.org/Writing_applications_with_the_MRPT_C%2B%2B_Library
          - Pointers have been passed to smart pointer all across the code.
          - RawLog files: a new "observations-only" format has been introduced, and now all rawlog are saved compressed using "gzip" automatically (they are decompressed automatically to the user when loaded). Alternatively the user can rename a rawlog file to "name.rawwlog.gz", then use standard tools to extract the uncompressed version, if necessary.
          - The MRPT libraries can now be compiled as a shared library (.dll/.so), by setting MRPT_BUILD_SHARED_LIB from the CMake GUI.
          - New hardware libraries supported:
                  - Cross-platform (Windows/Linux) library ARIA (distributed by ActivMedia Robotics under GNU GPL) integrated into MRPT. Select the appropriate switch in CMake to enable it. See hwdrivers::CActivMediaRobotBase.
                  - New hardware driver for XSens inertial measuring units (IMU). See hwdrivers::CIMUXSens.
          - New applications:
                  - RawLogGrabber, for gathering data in real-time from a robotic platform. See wiki page: http://www.mrpt.org/Application:RawLogGrabber
                  - hmtMapViewer, an inspection tool for HMT-SLAM. See wiki page: http://www.mrpt.org/HMT-SLAM:An_Open_Source_Implementation
          - Visual Studio 6 is not supported anymore from now on: it's a too old compiler, buggy, and lacks many modern C++ features.
          - Many bugs fixed.

  - All changes:
          - Many additions to conform to Debian packaging standards and freedesktop.org standard files for creating application menus, etc.
          - Added new "colored points" map & opengl objects. See mrpt::slam::CColouredPointMap and mrpt::opengl::CPointCloudColoured.
          - SceneViewer also is able to read from .gz'd files (.3Dscene files, but can be renamed to .3Dscene.gz if desired).
          - Management of local and UTC times clarifies with new methods. See mrpt::system, time functions.
          - Added a new class for transparent disk-swapped loading of very large datasets. see mrpt::slam::CRawlogXXL.
          - Exception handling prepared to correctly manage bad_alloc exceptions (for out of memory scenarios).
          - Added a 1D function interpolator using splines. See mrpt::math::CSplineInterpolator1D.
          - Added a 6D poses interpolator, using splines. See mrpt::poses::CPose3DInterpolator.
          - Removed built-in zlib library, replaced by wxWidget's one.
          - Added support for easy read and write of .gz files. For the automatic streams, see mrpt::utils::CFileGZInputStream and mrpt::utils::CFileGZOutputStream. For manual operation, see mrpt::compress::zip.
          - New opengl object: mrpt::opengl::C3DSScene for importing complete scenes from 3D Studio files (using the open source lib3ds library, Copyright (C) 1996-2007 by Jan Eric Kyprianidis <www.kyprianidis.com> ).
          - Class for storing rawlogs renamed as "mrpt::slam::CRawlog", and enabled for the new observation-only <a href="http://www.mrpt.org/http://www.mrpt.org/Rawlog_Format">rawlog file format</a>.
          - Introduced precompiled headers for a dramatic reduction of compilation time thru the header <mrpt/slam.h>.
          - The method CSerializable::duplicate has been optimized using directly the derived class copy constructor instead of a temporary memory buffer.
          - Created a new metric map: grid map of heights. See mrpt::slam::CHeightGridMap2D.
          - Added a method for estimating the Jacobian of a function by finite differences. See math::estimateJacobian.
          - Source tree has undergone a re-ordering and rename. Now, libraries are named as: mrpt-core, mrpt-hwdrivers, mrpt-ann, etc. and all the sources are in <mrpt>/src.
          - Added generic class for Levenberg-Marquart optimization problems. See utils::CLevenbergMarquardt and the <a href="http://www.mrpt.org/Levenberg%E2%80%93Marquardt_algorithm">wiki tutorial on the topic</a>.
          - Added communications support for the new HOKUYO UTM-30LX (Windows and Linux). Refer to the <a href="http://www.mrpt.org/Example:HOKUYO_URG_Laser_Scanner" >wiki page</a>.
          - New method introduced to gas distribution mapping: optimized Kalman filter with constant time update. See mrpt::slam::CGasConcentrationGridMap2D.
          - The class utils::CTicTac now does not use dynamic memory, so it's constructor & destructor are faster.
          - Several optimizations applied to 2D and 3D geometry classes (poses::CPoseOrPoint derived ones).
          - Added cross-platform support for "alloca". See system::alloca.
          - Sources updated to be compatible with GCC 4.3 and Visual Studio C++ 2008.
          - Thread statistics now are also implemented for Linux. See system::getCurrentThreadTimes.
          - HWDRIVERS classes unified under the "generic sensor model". See hwdrivers::CGenericSensor.
          - 3D render canvas classes unified under the new class utils::WX_gui::CMyGLCanvas_Base.
          - Added serializable STL classes. See utils::vector_serializable, etc. See utils/stl_extensions.h
          - Added serialization to the whole mapping framework state in HMT-SLAM, and many related classes. See mrpt::hmtslam::CHMTSLAM.
          - lib_hwdrivers: Custom device-dependent initialization commands can be sent when opening a GPS interface. See hwdrivers::CGPSInterface.
          - Joysticks and game-pads fully supported now under both Windows and Linux. See hwdrivers::CJoystick.
          - Added new applications:
                  - RawLogGrabber, for gathering data in real-time from a robotic platform. See wiki page: http://www.mrpt.org/Application:RawLogGrabber
                  - hmtMapViewer, an inspection tool for HMT-SLAM. See wiki page: http://www.mrpt.org/HMT-SLAM:An_Open_Source_Implementation
          - Added new examples:
                  - /samples/UTILS/fileSystemWatcher: Demonstrating watching of directory changes. Based on class utils::CFileSystemWatcher.
          - RawLogViewer:
                  - A new facy custom tree view, extremely more efficient for very large datasets and with a time-line to graphically visualize timestamps.
                  - Many new commands: resort from timestamps, regenerate timestamps from GPS observations, etc.
                  - In the "raw-map" window the user can change now the number of types of maps to build from odometry + raw observations.
                  - Implemented building a map from a rawlog with RTK GPS data. See "RawMap" dialog.
          - BUGS FIXED:
                  - Textual representation of dates and times with seconds represented with just one digit.
                  - Fixed wrong computation of transformation from GPS to local coordinates.
                  - Exception raised if an empty CImage is serialized.
                  - Wrong conversion of old serialization versions of gridmaps.
                  - Parameters of a gas gridmap were ignored after loading from .ini.
                  - Changing by hand the coordinates in mrpt::poses::CPose3D was not persistent when serializing the object.
                  - Added missing "+ operators" to mrpt::poses::CPoint3D.
                  - mrpt::slam::CSimplePointsMap: Serialization was not cross-platform (it used "unsigned long" data type).
                  - mrpt::slam::CObservationGPS didn't save the "sensorPose" when streaming.

  - MAY-2008:
          - mrpt::poses::CPointsMap now also has a horizontal tolerance range for "horizontal" or "planar" maps.
          - Pseudorandom number generator algorithm Mersenne twister MT19937 implemented in utils::RandomGenerator for uniform distributions (in turn used for the rest). This assures same PRNs over different platforms.
          - gui::CDisplayWindowPlots now can also manage 2D bitmaps plots, that can be combined with 2D vectorial plots. See gui::CDisplayWindowPlots::image.
          - CPointsMap::compute3DMatchingRatio is now ~6 times faster (using KD-tree).
          - Missing implementation of KD-tree for 3D points in mrpt::poses::CPointsMap now complete.
          - Added support for file-system watching. See utils::CFileSystemWatcher.
          - SceneViewer:
                  - New option to allow free rotation and zoom of the camera even for scenes with the flag "followCamera".
          - RawLogViewer:
                  - Added importer for "rtl" log files.
                  - Added capability to export several GPSs to text files.
                  - Sensor labels appear in the tree view.
          - BUGS FIXED:
                  - "mrpt::slam::CSensFrameProbSequence::operator =" was wrongly implemented.
                  - In gridmaps (mrpt::slam::COccupancyGridMap2D):
                          - Calling mrpt::slam::COccupancyGridMap2D::resizeGrid only supports growing the grid (not shrinking). This is now forced internally to fix impredictable results.
                          - In some situations, inserting a 2D laser scan ray ending very close to the border didn't make the grid to extend its size, and may lead to memory corruption.
                          - Disabled ROWSIZE_MULTIPLE_16 in mrpt::slam::COccupancyGridMap2D to avoid rare memory corruptions (bug to be tracked down if wanna enable it in the future again...).
                  - Fixed support for Bumblebee in external applications through CMake system (MRPTconfig.cmake).
                  - Wrong reporting of stacked exceptions messages.
                  - Fixed wrong calculation of (x,y,z) coordinates from latitude, longitude and height, in mrpt::slam::CObservationGPS.
                  - utils::CClientSocket did send debug information in the middle of actual data!. Thanks to Vicente Arevalo for reporting.
