# v01-14
* 2020-09-26 Markus Frank ([PR#717](https://github.com/aidasoft/dd4hep/pull/717))
- Propagate condition names for printouts. Names are enabled by default. The feature can be disabled
to minimize conditions memory footprint. Comment `DD4HEP_CONDITIONS_HAVE_NAME` in `DD4hep/config.h`
- If the debug flag `DD4HEP_CONDITIONS_DEBUG` is set (enabled by the compile definition `DD4HEP_DEBUG`, which in turn is enabled by the cmake flag `DD4HEP_BUILD_DEBUG`, which is turned on in debug builds automatically), then condition objects offer optional storage e.g. to store the object address or an xml-string etc.
- Update and fix some tests, which were assuming names
* 2020-09-25 Marko Petric ([PR#715](https://github.com/aidasoft/dd4hep/pull/715))
- Rename `TruncatedTube` `zHalf` accessor with `dZ` resolves #714
- Add to `Trap` missing `dZ` accessor resolves #713
* 2020-09-23 Andre Sailer ([PR#712](https://github.com/aidasoft/dd4hep/pull/712))
- Cmake: add configuration option DD4HEP_BUILD_DEBUG, if ON or OFF enable or disable the DD4HEP_DEBUG definition
if not set, enable if BuildType is Debug, fixes #708
* 2020-09-23 bcouturi ([PR#709](https://github.com/aidasoft/dd4hep/pull/709))
- Added geoWebDisplay command that uses jsroot to render the Geometry, requires ROOT7 ROOTEve
* 2020-09-23 Andre Sailer ([PR#707](https://github.com/aidasoft/dd4hep/pull/707))
- DDG4.HepEvtReader: fix reading of input particles, fixes #706
- DDG4.HepEvtReader: fix the units, expecting GeV, mm as units of input files.
- DDG4.HepEvtReader: add abort if the file cannot be read, e.g., when the content doesn't match what is expected
* 2020-09-22 Marko Petric ([PR#710](https://github.com/aidasoft/dd4hep/pull/710))
- Fix variable name`SIGNATURE` in `Plugins.h` and `Plugins.inl` that conflicts with `#define` from `utmpx.h` in macOS libc implementation. Resolves #700
- Migrate CI from Travis-CI to GitHub Actions and include macOS and ubuntu18 tests
* 2020-09-17 Marko Petric ([PR#704](https://github.com/aidasoft/dd4hep/pull/704))
- Apply `clang-tidy` `llvm-header-guard` fixer
* 2020-09-16 Andre Sailer ([PR#705](https://github.com/aidasoft/dd4hep/pull/705))
- DDSim: add options to select which sensitive detectors are trackers and calorimeters, defaults unchanged
- DDSim: tweak log output formatting, logging goes now to stdout instead of stderr
- SiD example: remove `track_length_max` and `time_max` from silicon limits (fixes part of #703 )
* 2020-09-07 Markus Frank ([PR#702](https://github.com/aidasoft/dd4hep/pull/702))
- Add `starttheta`, `endtheta`, `endphi` xml accessors.
- Fix sphere shape creator and update shape example.
* 2020-09-04 Markus Frank ([PR#697](https://github.com/aidasoft/dd4hep/pull/697))
- Implement data member accessors for construction parameters in `Shapes.h`. As discussed in the thread cms-sw/cmssw#30931 it was felt that read-only access to the basic construction parameters of a shape would be highly useful.
* 2020-09-03 Marko Petric ([PR#699](https://github.com/aidasoft/dd4hep/pull/699))
- Set search order for python on macOS to search for system/framework python last (change in behavior of cmake 3.14->3.15)
* 2020-07-31 Markus Frank ([PR#692](https://github.com/aidasoft/dd4hep/pull/692))
- Protect XML file handling against non-existing files.
* 2020-07-30 Markus Frank ([PR#691](https://github.com/aidasoft/dd4hep/pull/691))
- Improve matrix helpers: Add extractors for scale and translation as `XYZVector` from `TGeoMatrix`.
- Add example to simulate the MiniTel with DDG4 using a HepMC input file
- Add example to load a sub-detector geometry from gdml.
* 2020-07-27 Markus Frank ([PR#690](https://github.com/aidasoft/dd4hep/pull/690))
1) New example to show the usage of multiple compact input files being processed from the command line.
The example illustrates how to maniplulate the opening and the closing of the geometry using the compact notation.
```
geoDisplay -input file:SiD_multiple_inputs.xml \
-input file:SiD_detectors_1.xml \
-input file:SiD_detectors_2.xml \
-input file:SiD_close.xml \
-print INFO -destroy -volmgr -load```
2) New example to scan the geometry starting from a given position in a certain direction. Command line like for g4MaterialScan.
The output shows then the pathes to the volumes traversed, the shape and the material of these volumes.
`g4GeometryScan --compact=DDDetectors/compact/SiD.xml --position=0,0,0 --direction=0,1,0`
Resulting output:
```

- The CAD volume plugin allows to embed valumes and shapes originating from Computer Aided Design drawings using multiple formats as they are supported by the open asset importer library (http://assimp.org ). The plugin can be used whenever the `xml` fragment matches the following pattern:
```xml
<XXX ref="file-name" material="material-name">
<material name="material-name"/> <!-- alternative: child or attr -->
Envelope: Use special envelop shape (default: assembly)
The envelope tag must match the expected pattern of the utility
dd4hep::xml::createStdVolume(Detector& desc, xml::Element e)
<envelope name="volume-name" material="material-name">
<shape name="shape-name" type="shape-type" args....>
</shape>
</envelope>
Option 1: No additional children. use default material
and place all children in the origin of the envelope
Option 2: Volume with default material
<volume name="vol-name"/>
Option 3: Volume with non-default material
<volume name="vol-name" material="material-name"/>
Option 4: Volume with optional placement. No position = (0,0,0), No rotation = (0,0,0)
<volume name="vol-name" material="material-name"/>
<position x="0" y="0" z="5*cm"/>
<rotation x="0" y="0" z="0.5*pi*rad"/>
</volume>
For sensitive volumes: add physical volume IDs:
<volume name="vol-name" material="material-name"/>
<physvolid name="layer" value="1"/>
<physvolid name="slice" value="10"/>
</volume>
</XXX>
```
