[GNC] GNUCash XML format compatibility

[Wirawan Purwanto]

Hi,

I wonder if anyone has a pointer on the changes in Gnucash XML format
that can cause incompatibility across program versions. I have a
scenario where one OS uses Gnucash 2.6.x series whereas the other uses
3.5. I am concerned when transporting data file back and forth, if
there is corruption due to incompatible file format.

In my recent trial to migrate files back and forth between 2.6 and
3.5, I noted that data seems to be intact. But in the 2.6 series, the
"cmdty:space" field has the value of "ISO4217" whereas in 3.5 it was
"CURRENCY". But I noted that a very old GNUCash version (2.4.10)
failed to read the dates correctly from the file that was saved by
3.5. All dates became "1969-12-31" when read in the 2.4 program.
Because of this I am not quite sure what is safe to do or not safe.
Would be nice if there is a prominent / easy-to-find web page which
tells end-user like me regarding file version incompatibility.
