When you open Facebook do you notice anything different?

Following the unveiling of its new, albeit almost identical, logo last week other design changes have been revealed - this time to the Friends and Groups icons.

In a blog post, a Facebook design manager has revealed how the woman in both icons is now in the forefront and she has a different hairstyle.

The previous icon (left) positioned the woman behind the man's left shoulder with what resembled a straight bob hair cut. The woman in the icon is now in the forefront with a different hairstyle (right). The man's hair has also been softened and the shoulders have been smoothed down

The man's hair has also been softened and the shoulders have been smoothed down. And these changes can also be seen in the redesigned Groups icon.

It is not known when the icons were updated, but the thought process behind the changes has been explained by the design manager Caitlin Winner on Medium.

The previous icon positioned the woman behind the man's left shoulder with what resembled a straight bob hair cut.

Ms Winner said she was 'dismayed' to find that the female glyph, or symbol, had a noticeable chip on her shoulder in the location where the male would have been placed.

'After fixing her shoulder I was tempted to remove the Darth Vader-like helmet and give her hair some definition...eventually I landed on a slightly more shapely bob.'

She experimented with lining the two icons next to each other, but said the icon looked like a 'two-headed mythical beast.'

The updated Friends icon now appears on the mobile, desktop and app versions of Facebook on the Requests tab. This is true for the Groups icon too on the Groups tab, however, the icon for a person's Friends list is the previous version. Advertisement

'As a woman, educated at a women’s college, it was hard not to read into the symbolism of the current icon, the woman was quite literally in the shadow of the man, she was not in a position to lean in,' Ms Winner added.

So she decided to place the woman in the forefront.

The updated Friends icon now appears on the mobile, desktop and app versions of Facebook on the Requests tab.

This is true for the Groups icon too, however, the icon for a person's Friends list is the previous version.

Last week, Facebook product designer Christophe Tauziet tweeted the site's latest logo design. The blue and white colours have remained the same.

These changes can also be seen in the redesigned Groups icon (old left and new right).

Facebook has swapped the double-storey 'a' on the previous logo for a single-storey version.

This seems like an unusual change because the double-storey version is how the letter is typed - and is used across computer fonts including those on Facebook - while the single-storey is more commonly seen in handwriting.

By comparison, the 'b' now has a terminal and more closely resembles a typed version.

Other subtle changes include making the edges sharper and increasing the logo's width.

My Tauziet later responded to a question about when we will see the update with 'soon.'
