I like most of the recent changes so far, however, a new problem seems to have appeared with the latest update. As others have pointed out, text looks low-res and messy for certain users.
I've tried Opera, Chrome and Firefox, and unless I use 100% zoom in the browser, which results in a tiny window at higher resolutions, most in-game text gets hard to read. Text is somewhat easier to read in fullscreen mode, but still looks worse than before.
Both screenshots below were taken at the same level of zoom and at the same resolution. I couldn't find an old screenshot on my HDD with more text, but this illustrates the issue as well (left - old version; right - new version).
If you're not experiencing any problems with fonts and browser zooming, I'd like to ask which browser you are using.
