According to the developers, the only pre-3.x version of GnuCash that is expected to read data files that have been touched by a 3.x version is release 2.6.21, possibly with a suffix depending on the OS it is run in. When a file is first touched by 3.x there are some unspecified changes that may be at least partially mentioned in other threads here. They do not specify if there are any changes in the database variations, but there probably are.
