The backward incompatibility consists in that plugins to the gridftp
server compiled against an earlier version don't work with the 6.5-1
version in precise. The backward incompatibility was introduced with the
release of version 6.5-1 and has since been fixed. First by applying a
patch (debian release 6.5-6), and later in upstream which allowed the
patch to be dropped (6.10-1). So the gridftp server version in ubuntus
after precise can use plugins compiled against gridftp server versions
before precise. It is just the version in precise that is not compatible
with neither earlier nor later versions. So fixing the backward
incompatibility in pricise also means fixing forward compatibility.

The fix for the backward incompatibliity was tested by developpers of
gridftp server plugins and these developers were also very active in
both providoing input to how it should be fixed and in providing
confirmation that the applied fix was working. Admittedly this work was
mostly done on Scientific Linux 5 (using the EPEL version of the gridftp
server) and not with the Debian version, because SL is these developers'
main development platform, and alse the most common deployment plotform
for these plugins. The EPEL and Debian version of the globus packages
are however very simimilar.

The process of this testing is documented in
https://ggus.eu/tech/ticket_show.php?ticket=79541

There is not yet any package in Debian/Ubuntu that installs any plugins
to the gridftp server.
