## Tutorial about database change auditing¶

Joe asked whether Lino can do audit trails (history log). Yes it does. At least something similar. Here is the beginning of a tutorial: /tutorials/watch_tutorial/index.

I added a new demo fixture for lino.modlib.countries which yields both few_countries and few_cities. This is to avoid having to specify few_countries few_cities in demo_fixtures of Sites which use lino.modlib.countries. As a consequence lino_welfare/modlib/cbss/fixtures/demo.py had to be removed, and demo_fixtures for Lino Welfare changed accordingly. Which in the end is clearer than before.

## Started the next release of Lino Welfare¶

I’m going to upgrade the testlino instance at Gerd’s site because they are going to test the new eidreader using real cards.

• Incremented version counter of Lino Welfare
• Started to write lino_welfare.migrate.migrate_from_1_1_10(), which as expected is some more work than usual because there were extensive database changes in lino.modlib.cal.
