Tom Warren, on theverge.com:
Known as Microsoft Teams 2.0 or 2.1 internally, Microsoft has been working on this new Teams client for years. The app should use 50 percent less memory, tax the CPU less, and result in better battery life on laptops.
Praise the lords of kobol. I suffer through Teams at work. I tried, really tried to like it and use its features… but it’s soooo slooooooow.
Hope this is a significant upgrade, and I it includes the Mac version.
