I just tried to write a note & I was able to write 212 characters without any issue that's more than 1 line.
Still can't add line breaks in notes (Windows client).
2 new changes I think -
1. You can see losing hands.
2. when you fold your hand, you can still see your hands.
I believe there were more changes which @Swc_poker can tell us in detail.
Most of the reported bugs are still not fixed.
