The LASS message format is hardcoded in the LASS software. It may evolve over time, but it should avoide modifications because any modifications may result in failures of the existing backend data presentation/analysis tools.
For any changes made in the message format, please modify the variable VER_FORMAT in the source codes. It is recommended to change it incrementally by one for each update.
Once an update is made, please add descriptions of the changes in the below document (following the same description format).
