Why does FSEEK behave differently in MATLAB 7.0.1 (R14SP1) compared to earlier releases?

I am using FSEEK and FREAD to read a binary file. In previous versions of MATLAB, I could read less than a whole byte of data, call FSEEK, and then a subsequent call to FREAD would complete the read of a partial byte of data before going on to a new byte. In MATLAB 7.0.1 (R14SP1), it appears that the second call to FREAD starts at the beginning of the new byte.

We have verified that there has been a change in the way FSEEK operates in MATLAB 7.0.1 (R14SP1). Note that this change is a correction of past behavior that was considered a bug. The correct behavior as currently implemented is for FSEEK to ignore partially read bytes. That is, if you read a partial byte and then perform an FSEEK, the file pointer is set at the beginning of the specified byte, from where a subsequent call to FREAD will begin.
