The Centrifuge Council has increased the amount of seats from 7 to 9 as a part of the most recent Runtime Upgrade 1007. Before the upgrade, there were two runners up (Kirill and Ash) and they have now been elected and given a seat in the Council.
Some of the most important tasks of the Council are:
Proposing referenda for the benefit of the network and token holders
Vetoing malicious or dangerous referenda
Managing the Treasury (which also was enabled with this Runtime Upgrade)
Having a well diversified Council is important when discussing changes/voting for proposals and with this increase, more experience and expertise has been added to it.
This is the status of the current Council on Centrifuge
This means that there are now 9 councillors and 9 slots for the runners up.
