+       - fixes #320
+
+* 2018-01-24 Markus Frank ([PR#292](https://github.com/aidasoft/dd4hep/pull/292))
+  -  Fix bug in Alignment test:
+     - A long standing bug was fixed for the test `t_AlignDet_Telescope_align_new`.
+     - It was assumed that the `DetElements` were ordered in memory, which is **not** true (probably due to memory randomization).
+     - Moved to path dependent ordering. Test now OK.
+     - Closes #282 
+
+  -  Removed a Bunch of `rootcling` warnings
+     - Apparently `rootcling` now expects a class with the name of the dictionary header file.
+     - To satify this some dummy anonymous classes were added.
+     - Closes #290
+
+* 2018-01-26 Marko Petric ([PR#296](https://github.com/aidasoft/dd4hep/pull/296))
+  -  Check dynamic cast if it was successful
+
+* 2018-01-22 Markus Frank ([PR#289](https://github.com/aidasoft/dd4hep/pull/289))
+  - Add possibility to parse `XML` from string
+    - Please see  #288 for details.
+    - The main interface was not changed. Rather a view to the Detector class supports this functionality.
+     - The existing view `dd4hep::DetectorLoad` was enhanced to allow the required functionality:
+     ```cpp
+      Detector detector = ....;
+      /// So here is the actual test: We parse the raw XML string
+      DetectorLoad loader(detector);
+      loader.processXMLString(buffer,0);
+     ```
+     - An example was added (`ClientTests/src/XML_InMemory.cpp`, which illustrates the usage).
+
+  - Improve DDCond manual
+    - Improve that the DDCond manual reflects the source code.
+    - The possible plugins provided are not all described. This shall be future work.
+
+  - Enable the GDML reader plugin
+    - Closes #275
+
+* 2018-03-01 Markus Frank ([PR#325](https://github.com/aidasoft/dd4hep/pull/325))
+  - Add dictionaries to `DDRec`.

+      - add DetectorData classes to python 
+      - add example `dumpDetectorData.py`

+  - Remove unnecessary `import exceptions` from python
+
+* 2017-11-30 Markus Frank ([PR#272](https://github.com/aidasoft/dd4hep/pull/272))
+  ### DDG4 enhancements
+  - Enable framework support in DDG4. The `Geant4Context` is the main thread specific accessor to the `dd4hep`, `DDG4` and the user framework.
+      - The access to the `dd4hep` objects is via the `Geant4Context::detectorDescription()` call,
+      - the access to `DDG4` as a whole is supported via `Geant4Context::kernel()` and
+      - the access to the user gframework using a specialized implementation of:
+      `template <typename T> T& userFramework()  const;`
+
+      A user defined implementations must be specialized somewhere in a compilation unit of the user framework, not in a header file. The framework object could host e.g. references for histogramming, logging, data access etc.
+
+      This way any experiment/user related data processing framework can exhibit it's essential tools to `DDG4` actions.
+
+      A possible specialized implementations would look like the following:
+    ```cpp
+      struct Gaudi  {
+        IMessageSvc*   msg;
+        IHistogramSvc* histos;
+        ....
+      };
+      template<> Gaudi& Geant4Context::userFramework<Gaudi>()  const  {
+        UserFramework& fw = m_kernel->userFramework();
+        if ( fw.first && &typeid(T) == fw.second ) return *(T*)fw.first;
+        throw std::runtime_error("No user specified framework context present!");
+      }
+    ```  
+      To access the user framework then use the following call:
+      ```cpp
+      Gaudi* fw = context->userFramework<Gaudi>();
+      ```
+      of course after having initialized it:
+    ```cpp
+      Gaudi * fw = ...;
+      GaudiKernel& kernel = ...;
+      kernel.setUserFramework(fw);
+    ```
+
+  - `G4RunManager` is now a plugin. To enable user defined run managers in `DDG4`, the run manager is encapsulated in a `Geant4Action`. See `DDG4/plugins/Geant4RunManagers.cpp` how to implement such plugins. Currently there are to factories implemented: 
+     -  `G4RunManager` -> factory invokes the single threaded `G4RunManager`
+     -  `G4MTRunManager `-> factory invokes the multi threaded `G4MTRunManager`
+
+    The factory names here are identical to the names of the native G4 classes.
+
+* 2017-11-30 Marko Petric ([PR#268](https://github.com/aidasoft/dd4hep/pull/268))
+  - Introduce new DD4hep web-site: http://dd4hep.cern.ch/
+    - Page is automatically build from [this repo](https://gitlab.cern.ch/CLICdp/DetectorSoftware/DD4hep-website)

+  - Fixes to Doxygen configuration
+    - create reference manual `make reference`
+  - Better integration of DD4hep tex documentation and cmake
+    - create manuals in PDF format `make pdf` create manuals in HTML format `make html`
+    - allow creation of documentation if dependencies are not present
+  - extended gitlab runners to automatically build documentation PDF and HTML and also reference manual and publish to web-site, thus ensuring always up to date information.
+

+
+* 2018-02-16 Andre Sailer ([PR#315](https://github.com/aidasoft/dd4hep/pull/315))
+  - DDG4::ExtraParticles: particles with too small life time were tagged as stable, now correctly marked unstable

+
+* 2017-12-05 Marko Petric ([PR#278](https://github.com/aidasoft/dd4hep/pull/278))
+  - Remove `DD4HEP_USE_CXX11` and `DD4HEP_USE_CXX14` and use [CMake default way](https://cmake.org/cmake/help/v3.1/variable/CMAKE_CXX_STANDARD.html)`CMAKE_CXX_STANDARD` to define C++ standard
