 it is the number of cores. In case you have SMT enabled and `num_hwthreads`
 is not the number of cores the core hours will be too high by a factor!
 
+** NOTE **
+If you are using the sqlite3 backend the `PRAGMA` option `foreign_keys` must be
+explicitly set to ON. If using the sqlite3 console it is per default set to
+OFF!  On every console session you must set:
+```
+sqlite> PRAGMA foreign_keys = ON;

+```
+Otherwise if you delete jobs the jobtag relation table will not be updated accordingly!

 **Notable changes**
 * Supports user roles admin, support, manager, user, and api.
 * Unified search bar supports job id, job name, project id, user name, and name
