What’s New

Version 19.12.10

What’s New
• For those who love to format their messages on the move, good news, you can now get that done in a few clicks using the new formatting tool in the message field.

Bug Fixes
• Fixed: When loading messages containing a lot of custom emoji, the app was sometimes getting overexcited to the point of paralysis. We have chilled the app out, and this should no longer happen. Emoji away.
• Saving a file from Slack, and then attempting to open it from the Files app was occasionally causing the app to crash (which was bad). It is now causing the file to open (which is better).

just wished for a setting that allows compressed photos upload, regardless of mobile data or wifi connections


Good to use

It’s the best collaboration tool I have ever used, but will my boss see my messages? (Slack privacy announcement said they will hand in chat records to corporations, if they pay)


The new app icon is ugly af

Who designed the new icon? The original one was millions of times better looking. The new one looks so ugly. Your new designer needs to go back to school and learn about colors.
