A host of new features have been added to popular secure instant messaging service WhatsApp.
The developer of the software released no less than five updates in the space of just 24 hours – and all of the latest features are available on version 2.12.194.
Possibly the biggest change among the new features is the introduction of a 'mark as unread' facility.
It is hoped that users will never forget to reply to a message because of this function – and this could certainly prove useful for those who forget to reply to messages if they're out and about or busy at work.
Messages can be marked as unread by simply tapping and holding the conversation. They will then be returned to the 'green' status they had when they were first received.
The order of the chat history and the read message inside each conversation will remain unaffected.
Another new feature is a custom notifications setting, which offers users the chance to mute a conversation for eight hours, one week or one year.
Further customisation options have also have been added for tones, vibration lengths and pop-up notifications.
Low data usage options for voice calls have been implemented, which is ideal for those on limited data tariffs.
New sections of the app show Google Drive backup usage, which could indicate that the feature is set to return after it was introduced and deleted earlier this year.
The update is being rolled out across various devices gradually, but can be downloaded manually for anyone desperate to get the new features as soon as possible.
