  • BUGFIX: The Organizer field was sometimes different for individual events vs the repeat event declaration in an ICS file, which caused parsing errors for some CalDAV servers, and was against the spec.

April 1, 2024

  • CHANGE: Email unsubscribe requests must now be properly DKIM signed.
  • CHANGE: We now include a 'Resent-From' header whenever we include a 'Resent-Date' header, as required by RFC 5322.

  • INTERNAL: Optimized the bounce system.

March 25, 2024

  • BUGFIX: We were incorrectly adding a Bounced User log entry when we sent bounce notice messages to bouncing members.

March 21, 2024

  • CHANGE: When a user who is going through the reverification process visits the site, they are now redirected to a special page which lets them change their email address or send a new reverification email. Simply visiting the website no longer automatically reverifies someone.
  • CHANGE: The reverification email now includes a link to a new web page, which when visited, reverifies the user. Simply responding to the reverification email will also still reverify the user.

March 20, 2024

  • CHANGE: When a bouncing user visits the website, they are now directed to a special page which lets them change their email address or send a bounce probe email. https://beta.groups.io/g/main/topic/104774546#msg37751
  • CHANGE: We now always send an email notification to a member when they RSVP to an event, regardless of what the RSVP is. Also, events with a max number of attendees now also have ICS files formatted with METHOD=REQUEST so that members can RSVP directly in Outlook and other calendars. https://beta.groups.io/g/main/message/37722

March 15, 2024

  • BUGFIX: Include descriptions in #file-notice messages when adding new links.
  • SYSADMIN: Started sending email through remaining new servers.

March 14, 2024


March 13, 2024

  • BUGFIX: In some cases we were improperly encoding the 'To' header line for group & sender replies, leading to bounces from GMX associated servers.

March 12, 2024

  • SYSADMIN: Started sending email through a fourth email server.

March 11, 2024

  • CHANGE: Reverted the change where we re-write the Date header of emails. Instead, we now add a Resent-Date header.
  • MISC: Began new reverification process for some groups confirmed to have spam trap addresses.

March 8, 2024

  • BUGFIX: When a member leaves or is removed from a parent group, causing them to also be removed from any subgroups they are a member of, it was not logged in the activity logs of the subgroups that they had been removed or left.
  • BUGFIX: In some instances, it was not possible to edit extra member data fields in a member's group profile page.

March 6, 2024

  • BUGFIX: Fix permission errors when event organizer tries to modify events.

March 5, 2024

  • CHANGE: Switched DKIM signing to a 2048-bit key, as required by iCloud and others.
  • CHANGE: Strip any 'ARC' related headers from incoming group emails.
  • BUGFIX: In some instances, when uploading a directory to the Files section, one of the files would be rejected if it was at the top level.
  • CHANGE: For group messages, we now change the Date header to be the current date/time when we send the message to members. This is because some mail servers will reject messages with a Date that is too far in the future or past. We do not modify the Date header as it is stored in the archives.

February 29, 2024

  • SYSADMIN: A bunch of security changes to the production fleet.

February 28, 2024

  • SYSADMIN: Fixed incomplete SPF DNS records for \*.groups.io subdomains.
  • INTERNAL: Revamped our DNS publishing system.
  • CHANGE: We're now publishing 'DMARC p=none' records for all domains and subdomains that we host. This is to comply with recent Gmail changes.
