The update follows the app’s adoption of encrypted messaging; Wire was was the first major messaging platform to roll out end-to-end encryped messages for all of its users. WhatsApp followed a few weeks later.
Now the company claims it’s the first to roll out encryped file-sharing for any file extension- PDFs, PowerPoints, APKs, whatever. Previously you could only share images natively.
The file transfers work in groups of up 128 participants. On desktop you can share any file on your comptuer, while on mobile you can attach both locally stored files or items stored on cloud services like Google Drive, Dropbox or iCloud.
In a smaller update for Android users, you can also now reply to messages directly from push notifications.
