Taken from the changelog:

New functionality, features: <<< – General:
* The brand-new C++ interface for most of OpenCV functionality
(cxcore, cv, highgui) has been introduced.
Generally it means that you will need to do less coding to achieve the same results;
it brings automatic memory management and many other advantages.
See the C++ Reference section in opencv/doc/opencv.pdf and opencv/include/opencv/*.hpp.
The previous interface is retained and still supported.

* The source directory structure has been reogranized; now all the external headers are placed
in the single directory on all platforms.

* The primary build system is CMake, http://www.cmake.org (2.6.x is the preferable version).
+ In Windows package the project files for Visual Studio, makefiles for MSVC,
Borland C++ or MinGW are note supplied anymore; please, generate them using CMake.

+ In MacOSX the users can generate project files for Xcode.

+ In Linux and any other platform the users can generate project files for
cross-platform IDEs, such as Eclipse or Code Blocks,
or makefiles for building OpenCV from a command line.

* OpenCV repository has been converted to Subversion, hosted at SourceForge:
http://opencvlibrary.svn.sourceforge.net/svnroot/opencvlibrary
where the very latest snapshot is at
http://opencvlibrary.svn.sourceforge.net/svnroot/opencvlibrary/trunk,
and the more or less stable version can be found
