### Fixed

-   Bug in `AggregateMarking` encode and decode functions 1 octet offset causing problems with Aggregate State PDU's

### Added

-   `Point_Object_State_PDU` PDU
-   `EulerToHeadingPitchRoll` conversion to `KConversions.h`

-   Bug in `Gridded_Data_PDU` where `GRIDDED_DATA_PDU_SIZE` was incorrectly set to `32` instead of `64`
-   Bug where all protected PDU status member variables belonging to the `Header` class to become `public`. Caused by using anonymous unions
-   Compilation error _Compiler Error C2635_ when casting from `Header` to a derived class. Caused by `virtual` inheritance

## 1.12.0 - 2009-11-23

### Added

### Added

-   `Environmental_Process_PDU` PDU
-   `Environmental_Process_PDU` example
-   `DecimalToDMS` and `DMSTODecimal` to `KConversions.h`
-   Initial support for `DIS` version `7`. `DIS` version can be specified via `CMake` or pre-processor definitions

-   Missing PDUs in `PDU_Factory`
-   `KException` new constructor allowing for more details to be added

### Changed

-   `Send` example uses a while loop to continuously send the PDU. Some applications do not always pick up the first PDU

### Fixed

-   Some of the `Vector` operators would return the referenced objects and not the new copy of the object. This effected operators `*`, `+` and `-` (thanks Michael)
-   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`

### Added

-   Missing destructor implementation to `Action_Response_R_PDU`
-   `virtual` to all destructors to it is called even when a base pointer is deleted

-   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`
-   Default constructor initialize all data types to zero (if not already)

-   `IsGroupOf_PDU` PDU
-   `IsPartOf_PDU` PDU
-   `MAX_PDU_SIZE` of `8192` from `1278.1-200X` standard
-   `KRef_Ptr` class. This is an implementation of referenced pointer, designed to prevent memory leaks where memory needs to be dynamically allocated
-   `HeadingPitchRollToEuler` to `KConversions.h`

### 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

### Fixed

-   Some catch blocks catch all exception types rather than just `KException`

## 1.8.2 - 2009-05-26

### Changed

-   `Linux` support (thanks Anthony)

### Added

-   `Record_R_PDU` PDU
-   `Record_Query_R_PDU` PDU
-   `Set_Record_R_PDU` PDU

### 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

## 1.7.0 - 2009-05-11

-   All PDU automatically set the Protocol Version

### Removed

-   `KDIS_NEWORK_ENDIAN` from `KDefines.h`
-   Removed line in `Example_Send` that sets the Protocol Family as this is now done automatically in the constructor

### Fixed

-   Bug in `GetData` function of `Signal_PDU`
-   Bug in `Decode` function of `Create_Entity_PDU`
-   Bug in `CMakeLists.txt` where file `Entity_State_Update_PDU.h` was not being included
-   Bug in `Simulation_Management_Header` constructor where protocol family is not set
-   Bug in `SEES` constructor where protocol family is not set

## 1.5.4 - 2009-03-12

-   Interface in `VariableDatum` for setting an arbitrary binary stream

### Fixed

-   `VariableDatum` encoding and decoding
-   `VariableDatum` bits/bytes mix up
-   Typos in comments
-   Because of needless `Microsoft Word` garbage, the changelog has been rewritten

## 1.5.2 - 2009-03-04

### Fixed

-   `Comment_PDU` constructor where the PDU type and length were not initialized
-   `DESIGNATOR_PDU_SIZE` was incorrect, should be `88`, due to a typo in the `IEEE` standard
-   `EncodingScheme` bits were incorrect on Big Endian machines

## 1.5.1 - 2009-03-02

### Added

-   Support for `DIS` version `5` in `PDU_Factory `

## 1.5.0 - 2009-02-20

### Added

-   `Intercom_Control_PDU` PDU
-   `Aggregate_State_PDU` PDU
-   `KDIS_LIB` (static library) and `KDIS_DLL` (shared library) examples
-   [`CMake`](https://cmake.org) which is a cross-platform, open-source build system. The `CMake` file has certain options that allow to specify the version of `DIS` to use (`5` or `6`) and if to link against a `static` or `shared` library. Any future examples will require the use of `CMake`

### 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"`_

## 1.4.0 - 2009-02-05

### Added

-   `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

### Fixed

-   `Entity_State_Update_PDU` PDU
-   `FF_ATC_NAVAIDS_PDU` PDU

### Changed

-   All `GetFunctions` that previously returned an object now return a reference/const reference

-   Licence from `GPL` to `LGPL`
-   Changelog in HTML format
-   `IsMachineBigEndian` use static variables providing a very small performance boost

### Removed

-   `#ifdef _win32` for primitive data types in `KDefines.h` that was prevented any other OS from working

### Fixed

-   Bug in `Comment_PDU` where the PDU length was incorrect while reading variable datum lengths since the returned variable datum lengths value was in bits

### Changed

-   `Signal_PDU` data length is number of bits instead of octets
