The obvious first change was replacing the muted tan with a vibrant yellow. And the font is smaller.
The second thing is thekinda of copied DeviantArt custom logos that removed the frayed three point ends on the T and A. It’s a straight point now.
Probably the biggest difference is the letters no longer overlap whatsoever. On the original the top of the T overlapped the bottom part of the T and the left of the A was over the bottom line that came out of the N. Instead the letters have spaces where they would’ve touched.
Which interestingly separates the top of the T from the bottom of the T and makes it look like an I, but with a a dash over it instead of a dot. I like it.
The final difference is they removed the tail that came off the N. Instead of have the line run from the T down the N and into the A, it stops with the top of the N. The A is then Pushed further left so it cuts off the bottom of the N instead and then starts its own new line completely the A. Making it easier to read the over TNA initials imo. I like it because it’s a good callback to the 2004 logo and it’s 2024 so it’ll be the 20th anniversary of it, but it’s still its own design.
