Signal - Private Messenger
2021-01-18 Version History
This update is filled with dozens of changes! Here are a few highlights:
• Adjust your media download
preferences to control when attachments get downloaded (Settings > Data
Usage). • We added support for longer
group names in languages like Hindi where the previous limit was too
small. • We raised the group call limit
from 5 to 8, so now you can call it • Share something funny from other apps with multiple Signal chats at the
same time. • Use the optional shortcut
to enable a shareable group link when you create a new group. • Additional file attachments can now be opened right from within the
app. • Now you can easily see the
latest Signal profile photo that your contacts have chosen, but we added an
option to always show system profile photos if you prefer the old behavior
(or start to miss the blurry photo of them from 9 years ago that has
travelled across multiple SIM cards). •
Video quality and size improvements. •
We fixed a bug that prevented iPad users from tapping Send when sharing
content from other apps, and another bug that prevented WebP images from
sending properly on iOS 14.
