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 namespaces 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].
• New library [mrpt-tfest], a refactor of the old [mrpt-scanmatching].
• 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.

See detailed changelog.
