New WhatsApp Update: 4 Work-Group Features, and the Riskiest Sends Newcomers the Last 100 Messages

On 29 October 2026 WhatsApp announced four updates for groups: pinning important messages with no expiry, sending message history to someone who has already joined by tapping their name, a status that only one group's members can see and that disappears after 24 hours, and a filter that gathers the chats where you were mentioned or replied to. If you run your team or branches through WhatsApp groups, three of these features tidy up the work straight away, and one needs a decision before anyone uses it: a new member, whether an employee or a client you added, can receive from 25 to 100 earlier messages. This week, open the settings of every work group, decide who holds that right, and pin your standing instructions instead of repeating them every day.

What did WhatsApp announce in the 29 October update?

According to the official WhatsApp Blog announcement, the four updates are:

• Pin messages for longer: pins used to expire after 24 hours, 7 days or 30 days; you can now keep an important message pinned forever without choosing a time limit up front. The ceiling stays at 4 pinned messages per chat, according to the WhatsApp Help Center.
• Send message history after someone joins: WhatsApp launched group message history on 19 February 2026, available only when adding a member. Now you can also send it retroactively after they join, just by tapping their name in the chat, including people who joined through an invite link.
• Group status: an update visible only to the members of a specific group, who can view it, react and add their own, and it disappears after 24 hours like a regular status.
• Filter by mentions and replies: a new chat filter that shows every unread group conversation where you were mentioned or received a direct reply, including @all messages.

As with most WhatsApp updates, the four features may not reach every phone on the same day, so update the app on your supervisors' phones first and check for them yourself.

Pins with no expiry: what should you pin in a work group?

The four-message limit turns pinning into a decision rather than decoration. In a team or branch group, these are examples of what deserves to stay at the top of the chat:

• The price list or the offers running this month.
• This week's working hours or shift rota.
• The emergency contact and the escalation path.
• A standing way of working: how an order is received, or the daily report template.

According to the Help Center, the admin decides whether members may pin, through the Edit group settings option in Group permissions, and every pin shows everyone a system message naming who pinned it. Permanent pins have a flip side: an old price list stays pinned until someone removes it, so make reviewing pinned messages a monthly task for a named person. One point many people miss: someone who joins after a message was pinned does not see it, unless someone sends them message history that includes the pinned messages.

The last 100 messages for a newcomer: the feature that needs a decision

When you add someone to a group, or now after they join, you can send them the recent messages: from 25 up to a maximum of 100, according to WhatsApp's announcement of the feature, together with all pinned messages. The new member gets a notification, every member of the group sees a system message saying the history was sent, and the messages stay end-to-end encrypted. The history does not include disappearing messages, view once messages, live location or business transactions.

The benefit is clear: a new employee catches up in a minute instead of relying on screenshots and manual forwarding. But the last 100 messages in a work group may carry customers' mobile numbers, a special price you gave one client, an internal discussion about a supplier, and a colleague's leave. And if your group brings the team together with a client or supplier on one project, any new member, internal or external, is one tap away from context that was never written for them.

Three points from the Help Center change how you should handle the feature:

• An admin can turn off message history for members under: group name, then Group permissions, then Send message history, and this option is available when members are allowed to add others. Admins themselves can always send it.
• When someone joins through an invite link, group members see an in-chat option to send message history next to their arrival.
• If the recipient reports content in a history you sent, the report counts against you, not against the person who wrote the original message, according to the page about sending message history.

In an October 2026 update to the February announcement, WhatsApp added that it is testing ways to send history with fewer clicks. The easier sending becomes, the more the decision about who holds it matters.

Mentions filter, group status and member tags: tools for a busy supervisor

• Mentions and replies filter: a supervisor following the groups of several branches only needs to open this filter to see what concerns them. Make it a rule in your team: a request that needs an answer mentions its owner by name.
• Group status: suited to a daily announcement for one branch, such as a change in working hours, because it disappears after 24 hours. Do not put anything in it that you will need to refer back to.
• Member tags: not one of the four updates, but WhatsApp pointed to them in the same announcement. Each member writes their role under their name in up to 30 characters, such as Jeddah branch supervisor or Accountant, according to the Help Center, so a new employee knows whom to ask in a group that can hold up to 1000 people, according to WhatsApp's groups page.

5 steps to set up your company's groups this week

1. Update WhatsApp on your supervisors' phones and confirm the four features appear.
2. In every group that includes a client or supplier, turn off message history for members, make adding members admin-only, and do not leave the invite link in circulation.
3. Choose up to 4 standing messages for each group, pin them with no expiry, and assign someone to review them every month.
4. Ask every member to add a member tag with their job role.
5. Write the request rule: anything that needs an answer mentions its owner by name, so it shows up in their mentions and replies filter.

What the update does not solve

A group is a conversation, not a system. It does not know who owns a request, its status or its due date, and it gives you no report of what was done this week. The history itself is spread across personal phones, and whatever reached the phone of an employee who has left is not something you can take back. If a group is receiving customer requests and handing them out to the team, that is a sign you need a system that tracks every request, as we explained in Work Orders: From WhatsApp Messages to a System That Tracks Every Request, and if your customers already ask on WhatsApp, start with who is answering your customer on WhatsApp right now.

The Origami view

The four updates make a work group tidier, but at the same time they make it easier to pass information to everyone who joins. The right question for a business is not whether to use WhatsApp, but what stays a conversation and what has to be recorded in a system with permissions and a log of who saw what.

At Origami we build custom systems and apps, from small projects to large platforms: a requests system that receives customer messages through the WhatsApp Business API and gives each request an owner, a status and a due date, or an app for field teams that replaces the site group, with a fast phased launch based on the project's scope.
