Version 1.3.0: Released 12-JAN-2015

- Most important changes: - Classes in libraries \ref mrpt_obs_grp and \ref mrpt_maps_grp now belong to new namespaces (mrpt::obs, mrpt::maps) instead of the old mrpt::slam - No more `using namespace`s polute MRPT headers. Errors in user projects missing `using namespace XXX` that might be formerly masked will now reveal. This is a good thing, though admitedly annoying... - New library \ref mrpt_nav_grp, subsumming the old \ref mrpt_reactivenav_grp. - New library \ref mrpt_tfest_grp, a refactor of the old \ref mrpt_scanmatching_grp. - Backwards compatible headers have been provided to ease the transition of user code for all those library changes. Warning messages will be shown recommending deprecated replacements. - Detailed list of changes: - Lib changes: - Clean up of the bad practice of `using namespace` in public scopes of headers. May lead to user code failing for missing `using namespace`s which were previously masked. - Namespace "slam" deprecated in libraries mrpt-obs and mrpt-maps (used for historical reasons): - New namespaces \ref mrpt_obs_grp and \ref mrpt_maps_grp. - #include files moved from old paths => - Backward compatible headers added in until mrpt 2.0.0 - New library \ref mrpt_nav_grp, subsumming the old mrpt-reactivenav (\ref mrpt_reactivenav_grp). - \ref mrpt_reactivenav_grp is now a meta-library, depending on \ref mrpt_nav_grp. - \ref mrpt_tfest_grp : Old library mrpt-scanmatching (\ref mrpt_scanmatching_grp) has been refactored, its API clean-up, and renamed \ref mrpt_tfest_grp - \ref mrpt_scanmatching_grp is now a meta-library, depending on \ref mrpt_tfest_grp. - These classes have been moved between libs for a more sensible organization: - mrpt::slam::CDetectorDoorCrossing ==> mrpt::detectors::CDetectorDoorCrossing - mrpt::slam::CPathPlanningMethod & CPathPlanningCircularRobot: \ref mrpt_slam_grp ==> \ref mrpt_nav_grp - Build System / General changes: - Many optimizations in function arguments (value vs ref). Forces ABI incompatibility with previous versions, hence the change to a new minor version number. - Updated embedded version of Eigen to 3.2.3 - Kinect: Dropped support for the CL NUI API, which seems discontinued. Alternatives in use are libfreenect and OpenNI2. - libfreenect is now detected in the system and used instead of compiling the embedded copy of it. - Embedded copy of libfreenect has been updated to (23/oct/2014). It now supports "Kinect for Windows". - More selective linking of .so files to avoid useless dependencies (Fixes #52). - (Windows only) MRPT can now be safely built with libusb support (Freenect, Kinect,...) and it will run on systems without libusb installed, by means of /DELAYLOAD linking flags. - More unit tests. - Changes in classes: - [mrpt-base] - New function mrpt::math::angDistance() - [mrpt-hwdrivers] - mrpt::hwdrivers::CIMUXSens_MT4: (by Joe Burmeister for Suave Aerial Software) - Upgrade to latest XSens SDK 4.2.1.

See docs for mrpt::maps::TMetricMapInitializer - Introduced mrpt::maps::TMapGenericParams to hold parameters shared in all maps. - [mrpt-obs] - CObservation::getDescriptionAsText(): New virtual method to obstain a textual description of observations. Refactoring of messy code previously in the RawLogViewer app. - [mrpt-vision] - mrpt::vision::CFeatureExtraction: Removed (unused) optional ROI parameter in detectors. - BUG FIXES: - mrpt::poses::CRobot2DPoseEstimator could estimate wrong angular velocities for orientations near +-180deg. - mrpt::system::CDirectoryExplorer::sortByName() didn't sort in descending order - Fixed crashes from MATLAB .mex files: mrpt::system::registerFatalExceptionHandlers() has no longer effect, and will be removed in future releases. (Thanks to Jesús Briales García for all the testing!) - Fixed potential crash for Eigen unaligned memory access in 32bit builds in mrpt::slam::CGridMapAligner and other places ([Closes #94](#94))
