• Typo in VariableDatum::GetAsString() function. "Fixed Datum:" should have been "Variable Datum:"
• Timer in Logger playback is not started until the log is fully loaded

1.10.0 - 2009-08-08

Added

• Dead Reckoning implementation in class DeadReckoningCalculator. This class calculates dead reckoning transformations for all dead reckoning algorithms. This feature is currently in BETA until all algorithms are verified to work correctly
• < operator to EntityType, AggregateType, AggregateIdentifier, and ClockTime
• *, +, +=, -, -=, and [] operators to EulerAngles, WorldCoordinates, and Vector
• ApplyDeadReckoning function to Entity_State_PDU

Changed

• Namespaces are no longer global when included in a KDIS header. This prevents KDIS from conflicting with other class/struct/enums that have the same name

1.9.2 - 2009-07-30

Added

• Missing destructor implementation to Action_Response_R_PDU
• virtual to all destructors to it is called even when a base pointer is deleted
• == and != operators to all data types and PDUs
• < operator to EntityIdentifier, and TimeStamp
• More comments

Fixed

• Incorrect namespace references in function comments

1.9.1 - 2009-07-26

Added

• Additional comments to several PDUs to help further explain each field
• GetEnumAsString<Enum Name>(KINT32 Value) function to all enumerations. These functions return the string value for an enumeration (99 -> "Value"). It can be enabled/disabled by declaring the macro KDIS_USE_ENUM_DESCRIPTORS in the pre-processor definitions or in KDefines.h file. This feature makes the library significantly larger: disable if not used. When disabled the GetEnumAsString<Enum Name> functions return the enumerated value as a string (99 -> "99").
• Website based on MediaWiki available at https://sourceforge.net/p/kdis/wiki/Main_Page

Changed

• Moved remaining enumerations from KDISEnums.h to EnumEntityInfoInteraction.h
• Replaced all uses of strnset with memset

Added

• IsGroupOf_PDU PDU
• IsPartOf_PDU PDU

Changed

• Country Type in EntityType constructor from KUINT8 to KUINT16

Removed

• using namespace std directives from header files to prevent std attributes being exposed in the global namespace causing potential clashes

Added

Removed

• RecordSpecification data type. Record Sets are now placed directly into a PDU. When a change is made to a RecordSpecification parameter it was not always possible to update the PDU size. Removing RecordSpecification fixes this problem. This only effects Transfer_Control_PDU

Fixed

• Bug in FixedDatum that caused template functions to give linker errors due implementation in source file instead of header file

Changed

• KDataStream only accepts KUINT16 rather than KUINT32, which could have resulted in various buffer overrun problems
• KDIS_EXPORT macro now searches the project for preproccesor deflagrate. Use either EXPORT_KDIS or IMPORT_KDIS. E.g: /D "EXPORT_KDIS"

• DIS_Logger_Record and DIS_Logger_Playback examples. Included captured data is generated by MAK VR-Forces 3.10
• GetAsString and ReadFromString functions to KDataStream. GetAsString converts the data stream into a hex string, whereas ReadFromString converts the string into a KDataStream. These two functions allow DIS data to be logged to a file and viewed at a later time

1.3.1 - 2009-01-30

Removed

• References to the incomplete Intercom_Signal_PDU from PDU_Factory, which should not have been accessible

1.3.0 - 2009-01-24
