+Face module changelog {#face_changelog}
+=====================
+
+Release 0.05
+------------
+
+This library is now included in the official OpenCV distribution (from 2.4 on). The
+cv::FaceRecognizer is now an Algorithm, which better fits into the overall OpenCV API.
+
+To reduce the confusion on user side and minimize my work, libfacerec and OpenCV have been
+synchronized and are now based on the same interfaces and implementation.
+
+The library now has an extensive documentation:
+
+-   The API is explained in detail and with a lot of code examples.
+-   The face recognition guide I had written for Python and GNU Octave/MATLAB has been adapted to
+    the new OpenCV C++ cv::FaceRecognizer.
+-   A tutorial for gender classification with Fisherfaces.
+-   A tutorial for face recognition in videos (e.g. webcam).
+
+### Release highlights
+
+-   There are no single highlights to pick from, this release is a highlight itself.
+
+Release 0.04
+------------
+
+This version is fully Windows-compatible and works with OpenCV 2.3.1. Several bugfixes, but none
+influenced the recognition rate.
+
+### Release highlights
+
+-   A whole lot of exceptions with meaningful error messages.
+-   A tutorial for Windows users:

+
+Release 0.03
+------------
+
+Reworked the library to provide separate implementations in cpp files, because it's the preferred
+way of contributing OpenCV libraries. This means the library is not header-only anymore. Slight API
+changes were done, please see the documentation for details.
+
+### Release highlights
+
+-   New Unit Tests (for LBP Histograms) make the library more robust.
+-   Added more documentation.
+
+Release 0.02

+-   New Unit Tests (for LBP Histograms) make the library more robust.
+-   Added a documentation and changelog in reStructuredText.
+
+Release 0.01
+------------
+
+Initial release as header-only library.
+
+### Release highlights
+
+-   Colormaps for OpenCV to enhance the visualization.
+-   Face Recognition algorithms implemented:
+    -   Eigenfaces @cite TP91
+    -   Fisherfaces @cite BHK97
+    -   Local Binary Patterns Histograms @cite AHP04
+-   Added persistence facilities to store the models with a common API.
+-   Unit Tests (using [gtest](http://code.google.com/p/googletest/)).
+-   Providing a CMakeLists.txt to enable easy cross-platform building.
