What's New in Slack

26.09.10

September 2, 2026

Bug fixes • Forwarded emails were crashing the party in disguise, showing up in channels wearing the icon and name of totally unrelated apps. Turns out that's not appropriate business attire. The masquerade is over, and these emails will now be clearly labeled as themselves.

User reviews

Works well

I love the catch me up button. It’s so simple and easy to see what you’ve missed while away

Photos

Not easy to upload photos from my iPhone

My job uses slack for everything.

Not everything can be communicated over a radio. Slack helps a lot, we can send pictures and videos so our managers can immediately understand the situation without having to give a coworker your personal information. We are also able to track projects and share ideas. If someone is out of the office you can still send them a quick msg, so when they come back they already know what’s going on. One of the best parts is because our company is global we can communicate ideas with people from different states. You’re never alone and can always reach out for advice.
