I recently upgraded our seafile server from pro 6.3 to pro 7.
One of our users just asked me, why he can’t import group members from a csv file anymore. Looking at the changelog, this feature has been introduced in version 5.0.1.
5.0.1 (2015.12.07) New features ... * Add importing group members from CSV file
Now it has been silently removed with version 7, as it seems. The same happend to the group discussion feature. I think, it’s not very user friendly to drop features without telling about.
