## Changes from ASTP 1.0.0 to 1.1.0
# Changed from ASTP 1.1.0 to 1.2.0
## API Changes
### FSFW Architecture
- New src folder which contains all source files except the HAL, contributed code and test code
- External and internal API mostly stayed the same
- Folder names are now all smaller case: internalError was renamed to internalerror and
FreeRTOS was renamed to freertos
- Warning if optional headers are used but the modules was not added to the source files to compile
### HAL
- HAL added back into FSFW. It is tightly bound to the FSFW, and compiling it as a static library
made using it more complicated than necessary
## Bugfixes
### FreeRTOS QueueMapManager
- Fixed a bug which causes the first generated Queue ID to be invalid
## Enhancements
### FSFW Architecture
- See API changes chapter. This change will keep the internal API consistent in the future
# Changes from ASTP 1.0.0 to 1.1.0
## API Changes
### PUS
- Added PUS C support
- SUBSYSTEM_IDs added for PUS Services
- Added new Parameter which must be defined in config: fsfwconfig::FSFW_MAX_TM_PACKET_SIZE
### ObjectManager
- ObjectManager is now a singelton
### Configuration
- Additional configuration option fsfwconfig::FSFW_MAX_TM_PACKET_SIZE which
need to be specified in FSFWConfig.h
### CMake
- Changed Cmake FSFW_ADDITIONAL_INC_PATH to FSFW_ADDITIONAL_INC_PATHS
## Bugfixes
- timemanager/TimeStamperIF.h: Timestamp config was not used correctly, leading to different timestamp sizes than configured in fsfwconfig::FSFW_MISSION_TIMESTAMP_SIZE
- TCP server fixes
## Enhancements
### FreeRTOS Queue Handles
- Fixed an internal issue how FreeRTOS MessageQueues were handled
### Linux OSAL
- Better printf error messages
### CMake
- Check for C++11 as mininimum required Version
### Debug Output
- Changed Warning color to magenta, which is well readable on both dark and light mode IDEs
## Changes from ASTP 0.0.1 to 1.0.0
# Changes from ASTP 0.0.1 to 1.0.0
### Host OSAL
