(moved to todo.txt)
There are some things that will be changed for version 0.6.0 that might break something in your site. Please read this section carefully before upgrading.
The mobile phone number for FE users will be moved to a separate extension. As a result, the SQL column name will change. The extension will offer an option to import data from the seminars extension.
The university-related fields for FE users (matriculation number, subject, semester) will be moved to a separate extension. As a result, the SQL column names will change. The extension will offer an option to import data from the seminars extension.
All m:n database relations will use real m:n relations instead of comma-separated lists.
Some code that is shared with other extensions will move to the oelib extension. You need to install the oelib extension before upgrading the seminars extension, or you site may be severely broken. In fact, you can even install the oelib extension right now so that you don't have to remember installing it when upgrading the seminars extension.
