* Compilation with gcc 4.4
2016-01-06 Dmitri Konstantinov
* Missing cross-section parsing added to HepMC2 reader

2015-04-21 Witek Pokorski
* ROOT reader and writer inherit now from Reader and Writer base classes
2015-04-03 Witek Pokorski
* optimisations in read_data method
2015-03-27 Andy Buckley <andy.buckley@cern.ch>
* Reduce/add HepMCDefs.h and SimpleVector.h to stubs for backward
compatibility, which include the modern equivalent headers and
produce preprocessor warnings. These should be conditionally
installed only when building in compatibility mode.
* Adding, removing, and tweaking feature detection macros.
* Adding backward compatibility typedefs to CrossSection,
HeavyIon, PdfInfo (i.e. without the Gen prefixes)
2015-03-26 Andy Buckley <andy.buckley@cern.ch>
* Overhaul of FourVector class and removal of FourVector.icc
* Differentiate between SmartPointer const and non-const
dereferencing and arrow operators, to pass on the constness
semantics to the contained type. This blocks accidents like
calling non-const modifying functions on a const GenVertexPtr or
const GenParticlePtr, which is not protected against by
e.g. shared_ptr<GenParticle>. Plus adding an operator for bool
comparisons to SmartPointer and (many) updates through the main
object classes to respect the newly invigorated constness
rules. Good!
* Changing GenEvent::event_pos() to return a FourVector ref rather
than the root vertex itself, and changing
GenEvent::offset_event(v) to two explicitly named
shift_event_by(v) and shift_event_to(v) methods.
2015-03-23 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* ReaderAscii and WriterAscii finished. IO_GenEvent is now only
backward-compatibility header file
* IO_Root divided into WriterRoot and ReaderRoot

IO_FileBase and IO_Base removed. Examples updated.

Attributes
2014-11-25 Andy Buckley <andy.buckley@cern.ch>

* improvement in Pythia8 example; possibility of setting number of events and passing conf and output file names as arguments
2014-10-22 Tomasz Przedzinski & Witold Pokorski
* Added ROOT I/O
* Added ROOT I/O examples
* CMake updated for use with ROOT
* Added check for C++11 to CMake. Now #ifndef BUILD_WITH_11 can be used in code
* GenPdfInfo, GenHeavyIon, GenCrossSection are now stored by shared_ptr not raw pointer
* GenPdfInfo, GenHeavyIon, GenCrossSection added to ROOT I/O and IO_GenEvent
Now they're properly written and read from/to text files and root files
2014-09-19 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Changed naming convention from HepMC3 to HepMC (namespaces, comments, defines, etc.)
* Changed PdfInfo to GenPdfInfo and changed names of the fields
* Changed HeavyIon to GenHeavyIon
* Added 'examples' directory. Currently only with pythia8 example
and with rushed Makefile that should be rewritten
2014-09-10 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Added README with coding standards for HepMC developers
* Added HEPEVT wrapper and sample test for it
2014-07-25 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Added cross-section sctruct
* Added prototype for Rivet interface on branch 'rivet'
2014-07-13 Andy Buckley <andy.buckley@cern.ch>
* Adding HepMC.h and Version.h headers.
* Use CXX and CXXFLAGS in place of CC,CFLAGS
* Adding ChangeLog and TODO to track developments.
2014-07-04 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Added PDFinfo and HeavyIon structs
2014-06-20 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Added Units class
2014-05-20 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Added serialization module for future ROOT interface
2014-05-13 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Improved and optimized in-memory representation prototype
2014-05-06 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Tested new in-memory representation prototype based on smart_ptr
2014-04-29 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Changed validation framework. Now it can be configured through config
files and can be used with selected with any (or none) of the tools
for which interface to HepMC3 is prepared
* Tested new in-memory representation prototype based on classes
acting like smart pointers
2014-04-22 Tomasz Przedzinski <tomasz.przedzinski@cern.ch>
* Added vertex position. Position accessor checks all vertices down the
decay tree for first vertex that has position set
* I/O classes updated to read and store vertex positions
