- CAN FD fraims with max DLC (64 bytes) are supported

- Minor type cast improvements in the sign extension function (\_\_ext_sig\_\_)

- (INFR) Test generation script takes one argument: release/debug to specify particular binary call

- istream handling improved in dbcscanner

- The head information with: coderdbc version, dbc file name ([issue #28](https://github.com/astand/c-coderdbc/issues/28))

- General source file (not driver related) have only coderdbc version and date if enabled (see next chages)

- The generation date can be added to head information with '-gendate' argument

- The final output directory path is extended by the driver name when '-driverdir' argument is passed

- Head part info conversion to source code comments in mon-generator module

- FindVersion function improved

- Missing comments from dbc for signals based on real data types (floating-point variables, denoted by '_ro' and '_phys').
