On September 27 Zoom is implementing a mandatory functionality change. Zoom will now enforce all meetings to have either a passcode or a waiting room. If no passcode is enabled, attendees will automatically be placed into a waiting room and the meeting hosts will need to add the attendees to the meeting manually.

You should be looking for updated meeting invites from lists.hyperledger.org that contain an embedded passcode as part of the zoom meeting URL. These notices will be tagged with #cal-invite.

Please be sure to sync your calendars if the updates are not reflected on your calendar tools. You can always subscribe to the calendar feed to stay up to date with any meeting changes by following the instructions below:
