The log file structure does not seem to match the description in the documentation in version 1.79

As described in the documentation and in the code. The logfile structure should be [flag seriesID measurementName tagKey tagValue checkSum],But whether they are locally generated or example files, they are similar to this format[0 175 215 47 0 0 0 182 162 96 100 0 214 159 47 0 0 0 242 12 47 229 0 232 159 47 0 0 0 204 124 73 56 0 183 215 47 0 0 0 89 39 224 146 0 209 19…].
Why measurement and tags are 0?
If this format is right. Why is this format?
