The programme manual has been slightly revised according the decision made in June by the Interreg Europe Monitoring Committee on the COVID-19 measures. A series of approved measures increase flexibility and allow additional activities for projects. 

You can get the new version of the programme manual here.

If you are using an older version of the manual, you might find useful to consult the track changes version  where the few changes compared to the previous version, last updated in March 2019, are highlighted.
