finally I managed to upgrade the Stamp collection module code so that it should work under Moodle 2.x. I did not release it in the Plugins database yet as there are some missing bits still and I believe it needs more testing. The version for 2.x can be downloaded at https://github.com/mudrd8mz/moodle-mod_stampcoll/downloads
Please note that this version does not add any new functionality yet (like the requested bulk mode etc). As announced in advance, I was primarily focused on having the basic features set available in Moodle 2.x.
The current 2.x version (living on the "master" branch in the Git repository) is supposed to
- upgrade successfully from 1.9 version
- keep the eventual custom stamp image during the upgrade
- support 2.x backup and restore (MBZ format)
The 2.x version does NOT
- support restoring 1.x backups yet (as Moodle core does not support restoring user data yet and without user data, there is not really much to restore in this activity)
I will really appreciate if you find time and try to install the 2.x version at your test sites and give me feedback on how things go. If you could test upgrade from 1.9 site, that would be great.
