  • INTERNAL: Spent most of the week dealing with a major, ongoing, bot scraper attack - adding additional defenses against it, adding additional monitoring, and optimizing systems.

August 19, 2026

  • CHANGE: Groups on the free plan are now notified when people try to join but can't. If your group is at the 100-member limit, owners and moderators receive a weekly email when join attempts were turned away, with a link to the activity log showing who tried. Denied join attempts that arrive by email are now recorded in the activity log as well.

August 17, 2026

  • INTERNAL: Added additional protections against bot group signups.
  • BUGFIX: Fixed a case where in rare circumstances, when a message is deleted, it should still show up on the group home page and in search results. https://beta.groups.io/g/main/message/40992
  • BUGFIX: Messages that had signature blocks that were very long (or had parts that looked like signature blocks that were very long) would not be included in search results.

August 7, 2026

  • BUGFIX: The About page link was incorrect.
  • CHANGE: Change the `Automatic` Dark Mode setting label to `Follow Device Setting`

August 5, 2026

  • BUGFIX: The website now listens for light/dark mode change events and adjusts the page accordingly, instead of waiting for full page reloads.

August 3, 2026

  • NEW: New demo videos: subgroups, billing, moderation, invite members, account recovery, co-owners, and delivery settings.

July 31, 2026


July 29, 2026

July 17, 2026

  • CHANGE: Merged Stephane Fillod's French translations. Thanks Stephane!
  • CHANGE: Updated all translations and corrected several issues.
  • CHANGE: The Ask feature now respects commands to only search messages/files/etc as well as better date handling.
  • CHANGE: When someone changes their RSVP to "Will Not Attend," they're now prompted for the comment right in the confirmation dialog, so collecting a reason for not attending works naturally.
  • CHANGE: Previously, changing an event response could silently erase a member's earlier comment. Comments now carry over.
  • CHANGE: There's a new per-event option, "Attendee comments are visible to all members." With it checked, everyone in the group can see the comments on the event's Responses page - useful for coordinating who's bringing what, or who's filling which position or location. Left unchecked, comments stay visible only to the event organizers, as today.
  • BUGFIX: For format=flowed text emails, we would strip trailing spaces after the `--` signature delimiter.

July 16, 2026

  • API NEW: Added the `/updatetopic` endpoint to update a topic's subject and hashtags, moderation, locked and sticky states, and reply-to setting.
  • API NEW: Added a machine-readable Groups.io API skill guide at `/api/SKILLS.md`.
  • CHANGE: "Group Profile" sidebar now opens the editable form.
  • CHANGE: Empty profile fields become actionable on your own profile; there is now a muted "+ Add" link next to each.
  • CHANGE: In Settings, added a note next to the existing profile-sync note - _"Custom fields defined by a group (for example Organisation or Job Title) do not appear here — they live on each group's own profile. To fill them in… Subscription > Group Profile … Edit Group Profile."_
  • CHANGE: Added help text under "Viewable In A Member's Profile" — _"When checked, members can view and fill in this field on their own group profile (Subscription > Group Profile). When unchecked, only moderators can see or edit it."_
  • DOCS: Updates from Nina. https://groups.io/helpcenter/single/revisionhistory
