        • mrpt::math::make_vector<> => std::vector<>{...} braced initializator

      • Removed the include file: <mrpt/math/jacobians.h>. Replace by <mrpt/math/num_jacobian.h> or individual methods in [mrpt-poses] classes.

      • Added: mrpt::system::WorkerThreadsPool

    • [mrpt-rtti] [NEW IN MRPT 2.0.0]

      • All classes are now registered (and de/serialized) with their full name including namespaces. A backwards-compatible flag has been added to mrpt::rtti::findRegisteredClass().

      • CLASS_INIT() macro for automatic registration of classes has been removed, since it is not well-defined in which order global objects will be initialized. Therefore, manual registration (as already done in registerAllClasses.cpp files) is left as the unique registration system.

Version 1.3.0: Released 12-JAN-2015

  • Most important changes:

    • Classes in libraries [mrpt-obs] and [mrpt-maps] 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 [mrpt-nav], subsumming the old mrpt_reactivenav_grp.

    • New library [mrpt-tfest], a refactor of the old 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 [mrpt-obs] and [mrpt-maps].

        • #include files moved from old paths <mrpt/slam/…> => <mrpt/{obs,maps}/…>

        • Backward compatible headers added in <mrpt/slam/…> until mrpt 2.0.0

      • New library [mrpt-nav], subsumming the old mrpt-reactivenav (mrpt_reactivenav_grp).

      • mrpt_reactivenav_grp is now a meta-library, depending on [mrpt-nav].

      • [mrpt-tfest] : Old library mrpt-scanmatching (mrpt_scanmatching_grp) has been refactored, its API clean-up, and renamed [mrpt-tfest]

      • mrpt_scanmatching_grp is now a meta-library, depending on [mrpt-tfest].

      • These classes have been moved between libs for a more sensible organization:

        • mrpt::slam::CDetectorDoorCrossing ==> mrpt::detectors::CDetectorDoorCrossing

        • mrpt::slam::CPathPlanningMethod & CPathPlanningCircularRobot: [mrpt-slam] ==> [mrpt-nav]

    • 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:

    • BUG FIXES:

Version 1.2.2: Released 12-SEP-2014

  • Changes in apps:

  • New classes:

  • Changes in classes:

    • Consistency in all “laser scan” classes: angular increments between rays are now FOV/(N-1) instead of FOV/N.

    • [mrpt-base]

      • New method mrpt::img::CImage::loadTGA()

      • IMPORTANT : Changed behavior of CSerializable/CObject macros (see bugfix below), introducing the new macros DEFINE_SERIALIZABLE_POST_*. May require changes in user code if serializable classes are defined:

        • Previous version:

          DEFINE_SERIALIZABLE_PRE_*(...)
class XXX {
  DEFINE_SERIALIZABLE(XXX)
};

        • Must be changed in this version to:

          DEFINE_SERIALIZABLE_PRE_*(...)
class XXX {
  DEFINE_SERIALIZABLE(XXX)
};
DEFINE_SERIALIZABLE_POST_*(...)

    • [mrpt-hwdrivers]

    • [mrpt-maps]

    • [mrpt-opengl]

  • BUG FIXES:

    • mrpt::img::CImage constructor from a matrix crashed.

    • Unit tests: Named semaphores are not tested anymore if it’s detected that the kernel version doesn’t support them (Fix Debian 758725).

Version 1.2.0: Released 25-JUN-2014

  • Most important changes:

    • Public header files (.h) have undergone a serious refactoring to minimize unnecesary dependencies and reduce compile time and memory as much as possible. As a side effect, user code might need to add new #include<> lines. This change justifies the new minor version series 1.2.X.
