   From Dirk Baechle:
     - Updated test framework to support dir and file fixtures and
-      added ability to test external (out-of-tree) tools.
+      added ability to test external (out-of-tree) tools (#2862).
       See doc in QMTest/test-framework.rst.
+    - Fixed several errors in the test suite (Java paths, MSVS version
+      detection, Tool import), additionally
+      * provided MinGW command-line support for the CXX, AS and
+        Fortran tests,
+      * refactored the detection of the gcc version and the according
+        Fortran startup library,
+      * provided a new module rpmutils.py, wrapping the RPM naming rules
+        for target files and further hardware-dependent info (compatibility,
+        compiler flags, ...),
+      * added new test methods must_exist_one_of() and 
+        must_not_exist_any_of() and
+      * removed Aegis support from runtest.py. (#2872)
 
   From Gary Oberbrunner:
     - Fix MSVS solution generation for VS11, and fixed tests.

+RPM specific helper routines for general usage in the test framework
+and SCons core modules.
+
+Since we check for the RPM package target name in several places,
+we have to know which machine/system name RPM will use for the current
+hardware setup. The following dictionaries and functions try to
+mimic the exact naming rules of the RPM source code.
+They were directly derived from the file "rpmrc.in" of the version
+rpm-4.9.1.3. For updating to a more recent version of RPM, this Python
+script can be used standalone. The usage() function below shows the
+exact syntax.
