WhatsApp introduces a new feature that allows editing messages that have already been sent. However, the editing window is small.
Corrections are made possible
Until now, errors in WhatsApp messages have to be corrected by sending another message. With the ability to delete sent messages, this has already changed a bit: The incorrect message can since be deleted and replaced by a new one. With a new feature, WhatsApp now wants to allow even easier corrections. So it will soon be possible worldwide to edit messages that have already been sent.
The function has been tested for about a year and is to be made available to all users in the course of the next few weeks via an update. The time window in which edits are possible is fifteen minutes after the message has been sent. This ensures that messages sent far in the past cannot be changed and conversation histories manipulated in this way.
Note of editing, but no change history
The fact that a message has been edited is clearly indicated in the chat. This makes it clear to everyone involved that it is not the message that was originally sent. However, an editing history will not be retrievable. Anyone who receives an edited message will therefore not be able to find out what it originally read.
WhatsApp has pointed out in connection with the presentation of the new function that the existing end-to-end encryption will remain in its current form. The editing function has no influence on this.
