-------------------------------------------------------------------------
CHANGES from version 0.9.5:
-------------------------------------------------------------------------
* fix overflow when decoding large integer numbers

-------------------------------------------------------------------------
CHANGES from version 0.9.4:
-------------------------------------------------------------------------
* fix possible memory corruption bug

-------------------------------------------------------------------------
CHANGES from version 0.9.3:
-------------------------------------------------------------------------
* Support for 15118-2-2016 (ISO2) started besides 15118-2-2013 (ISO1) and DIN
* fix eMAID fragment encoding/decoding support
* internal coding updates
* bug-fixes

-------------------------------------------------------------------------
CHANGES from version 0.9.2:
-------------------------------------------------------------------------
* resolves XML signature interoperability issue
  Note: To make use of xmldsig the following defines have to be set.
  in "xmldsigEXIDatatypes.h"
  #define DEPLOY_XMLDSIG_CODEC SUPPORT_YES
  #define DEPLOY_XMLDSIG_CODEC_FRAGMENT SUPPORT_YES
  in "v2gEXIDatatypes.h"
  #define DEPLOY_ISO_CODEC_FRAGMENT SUPPORT_YES
  Otherwise the code is turned off.

-------------------------------------------------------------------------
CHANGES from version 0.9.1:
-------------------------------------------------------------------------
* resolves bug with name clashes w.r.t. iso and din track
* fixes issue with test code for init handshake 
* Note: OpenV2G 0.9.2 is essentially just a bug fixed version of OpenV2G 0.9.1

-------------------------------------------------------------------------
CHANGES from version 0.9:
-------------------------------------------------------------------------
* includes support for DIN and hence interoperability with OpenV2G 0.7
  (needs to be switched on though by #define DEPLOY_DIN_CODEC)
* fixes bugs and warnings for Visual Studio
* Note: OpenV2G 0.9.1 is a superset of previous versions
  v2g...c/h files support ISO track
  din...c/h files support DIN track

-------------------------------------------------------------------------
CHANGES from version 0.8:
-------------------------------------------------------------------------
* large code footprint reduction which resulted in a new API
  (please take a look at the example in src/test folder)
* datatype differences w.r.t. arrays, strings, bytes, isUsed, and enum-naming
* bug-fixes
* Note: OpenV2G 0.8 and 0.9 are interoperable, meaning that one can generate
  streams with one and decode with the other or vice-versa

-------------------------------------------------------------------------
CHANGES from version 0.7:
-------------------------------------------------------------------------
* adaption of V2G schema changes (reflects the ISO/IEC 15118-2 FDIS status)
* bug-fixes

CHANGES from version 0.6:
-------------------------------------------------------------------------
* adaption of V2G schema changes (reflects the ISO/IEC 15118-2 DIS status and DIN 70121)
* reduced memory usage
* EXI decoder skips schema deviations according to EXI Profile
* bug-fixes

-------------------------------------------------------------------------
CHANGES from version 0.5:
-------------------------------------------------------------------------

-------------------------------------------------------------------------
CHANGES from version 0.4:
-------------------------------------------------------------------------
* adaption of V2G schema changes
* V2GTP implementation (replaces the DoIP implementation)
* EXI default coder for the 15118 schema (replaces the strict mode of EXI)
* AC demo interaction between PEV and EVSE, and
* DC demo interaction between PEV and EVSE


-------------------------------------------------------------------------
CHANGES from version 0.3.1:
