We have finally managed to get in the required reviews and editors decisions, and now also sent out the decision letters. Many e-mails bounced when we sent out the decision letters so please check your accounts on http://ifac.papercept.net. The deadline for final submissions is adjusted to April 4.
Some associate editors have not been able to gather the required reviews in time so we have to wait a bit more until we can send out the decisions. The final submission deadline will also be adjusted when we have the decisions ready.
