Update, 5/3/17: Google is beginning to roll out the new version of Allo, which will include chat backups, group incognito mode, and link previews.
When Allo 9.0 arrived earlier this month, there wasn’t much to talk about. Aside from bug fixes and performance improvements, the update brought nary a new sticker pack to play with. But according to a tweet by Allo chief Amit Fulay, a new update rolling out to users will bring some interesting features.
Backups have been a major issue with Google's messaging clients, but the new version of Allo takes a major step toward changing that. According to Fulay, the update brings support for chat backups and restores, a feature 9to5Google previously found in a deep dive into the APK. Presumably the feature will allow you to back up your chats to Google Drive, which can then be synced to a new phone, along with any images and videos. Google is also expanding incognito to include group chats and link preview, which will give you a snapshot of what's inside a URL before you click on it.
