Joined a group? WhatsApp will finally show you what was discussed before you arrived
WhatsApp is developing a feature that lets new members see the previous 24 hours of group messages without compromising end-to-end encryption.
Meta is continuing to refine WhatsApp’s group experience.
After years in which new members entered group chats without any context and relied on others to explain what they had missed, the platform is now testing a feature designed to ease that transition: a view of the group’s most recent message history.
The concept is straightforward.
When a new participant joins a group, they will be able to see messages sent during the previous twenty-four hours.
This will not appear as a full archive or group diary, but as a short window offering enough context to understand the ongoing conversation.
The feature is expected to apply to both users joining via link and those added manually by an administrator, activating automatically the moment they enter.
End-to-end encryption, a cornerstone of WhatsApp and Meta’s messaging philosophy, is not expected to be compromised.
To preserve encryption integrity, the system will automatically select an existing group member to share the most recent messages with the newcomer.
Each time someone joins, the app also generates a new encryption key for the entire group, ensuring that each participant can see only what they are permitted to see.
This process occurs silently in the background, without disrupting the flow of conversation.
The feature will appear in group settings, where administrators will be able to choose whether to enable it.
In the current beta version, new members can view only the last twenty-four hours of messages, though Meta may adjust this timeframe before a full release.
For highly active groups where hundreds of messages are exchanged daily, a full day’s chat history may be overwhelming.
Meta is therefore considering limiting the feature to approximately one thousand messages from the preceding twenty-four hours—though, realistically, few users are likely to read even a fraction of that.
The feature is designed to work in older, long-running groups as well as newly created ones, ensuring that anyone joining late—whether they missed an invitation link or were temporarily unavailable—receives an up-to-date snapshot of the discussion.
This is especially useful in large groups or fast-moving conversations, where newcomers often struggle to understand what is happening.
If, for example, a group has spent hours planning an event and someone joins midway, they will immediately see the relevant messages from the past day and can participate without asking, “What did I miss?” or reopening a decision the group had already resolved.
The feature is currently in development within the beta version for developers, and recent updates to the Android beta indicate that WhatsApp is already in the advanced stages of implementation.
It is expected to become available to users in the near future.
