Hi,
Is it possible to have a list of the files that have been changed in new update?
Yes : check the svn repository available at sourceforge.
Or is it an obligation to upload all the files of the new version?
Yes, it is, to be sure to get coherent updates.
By the way, you'll have to re-copy your updates into new files.
HINTS :
To avoid this constraint for objects (php classes), you can :
- create a new class extending the original object
- update the "menu" table to access your own classes
Then new deployments will overwrite original classes and not your own.
If you insert new common functionalities (for instance in projector.php), don't update existing files : create new files and just insert the include in the existing files : you'll just have to re-copy these includes on new deployments.
Regards.
