[Version Change] 2.7.6 to 2.8.0 [Approx. Date] 2003-Feb-14
Version 2.8.0 introduces a change to the format of the rollback journal file. The main database file format is unchanged. Versions 2.7.6 and earlier can read and write 2.8.0 databases and vice versa. Version 2.8.0 can rollback a transaction that was started by version 2.7.6 and earlier. But version 2.7.6 and earlier cannot rollback a transaction started by version 2.8.0 or later. The only time this would ever be an issue is when you have a program using version 2.8.0 or later that crashes with an incomplete transaction, then you try to examine the database using version 2.7.6 or earlier. The 2.7.6 code will not be able to read the journal file and thus will not be able to rollback the incomplete transaction to restore the database.
