If you're an obsessive designer, you might have seen a subtle tweak to Google's logo made over the weekend. If you're like the rest of the planet, you missed it.

Before we reveal what's new, we'll give you a chance to try to spot the difference. Here is the old logo:

And here is the new logo:

See anything different? The change made was a tiny shift in kerning -- or, the space between two letters -- of the "g" and "l," moving the "g" one pixel to the right and the "l" one pixel down and to the right.
看到不同吗?其实是对字母“g” 和“l” 之间的字距进行了很细微的调整。字母“g” 向右移动了一个像素,字母“l” 向右下方移动了一个像素。

The subtle difference supposedly makes the overall logo more pleasant on the eyes and easier to read.

Redditors spotted the change a few days ago, and a Google representative confirmed the tweak to The Huffington Post, saying, "Great to see people notice and appreciate even single-pixel changes -- we tweaked the logo a little while ago to make sure it looks its sharpest regardless of your screen resolution."

Here's a GIF that shows the change from old to new, for those of us who aren't kerning-obsessed:
