The old format is there: [CAN_Log_Trigger_3_2.asc](https://bitbucket.org/tobylorenz/vector_asc/src/47556e1a6d32c859224ca62d075e1efcc67fa690/src/Vector/ASC/tests/unittests/data/CAN_Log_Trigger_3_2.asc?at=master)

The solution could be to recognize the format in the header and then to parse differently depending on the version.
