Think so. It might also be a third party Twitter app called tweetcaster. Either way I like it - think it is softer and more welcoming.
Personally I prefer the round avatars! 
Iāll say it one last time. Itās not a matter of preference. I simply canāt see the new round ones.
Iām not sure what you mean here. You mean when the avatars changed from square to round you stopped being able to see them here? Or are just some of them too light to see?
I vote a reversion back to square
I thought it was me,initially i was going to ask the same question but didnāt want to look like a idiot.
When I try to add a pic it doesnāt work.
I canāt see what the pictures on the round avatars on the page where topics are listed. I can see them on this page where they are larger. I canāt see them where the red arrow isā¦theyāre even smaller.
I like the round ones better for some reason.
Theyāre not too light to see. I stopped being able to make out what the pictures were of when they change to the circles. I looked back and am able to make some of then out but it takes an effort to study the others + make out ones that are less recognizeable and there are those that I canāt identify. However I am just one leg on the centipede. No one else seems to have this problem. I can live without them.
Computer, and same computer where the square ones showed a row of avatars, not just oneā¦this is what I get since the change from square to roundā¦
This is what it looked like with the square avatarsā¦
Im kind of in the middle on the round avatars. I think there easier on the eyes but I also think the cut some of the avatar picture out. I havenāt noticed any other changes though.
i hate them, change them back pls 
i will not conform to your beliefs about circles over squares
Hereās MY vote:
10-96
Sorry folks - I just upgrade the software - I donāt develop it. We get what the developers give us. I canāt change it.
Easily fixed. Just need to put this into the main stylesheet for your theme:
img {
border-radius: 0px;
}
img.avatar {
border-radius: 0px;
}
The rounded corners are courtesy of a CSS hack. (They are currently set to 50% instead of 0px.)
10-96
In protest of Round avatars, I present Bubbles of the PowerPuff girls. Take that, whammm.
No big drama for me as I was rounding the corners somewhat previously. But do prefer a choice in the matterā¦I must be delusional⦠I thought we were living in a democracy.
The user cards do seem to come up a lot faster then I remember. So thatās one good thing. I remember was a long drawn out wait to get them to come up. I often had to click them like 5 times to lift them on the board. Now a simple click and itās there.
Hopefully they can do something about the Emojis as they are so very slow to load.
