Auto-detect new version of FontAwesome

I don't think that will be possible. Woltlab will include the new Version of FontAwesome within the next update (if necessary).

Any chance to get the male / female icons instead of the full text in the message sidebar?

can this be updated,some of the icons do not appear on the forum
I use correct code and it worked with previous Font Awesome icons

this works
[data-board-id="3"] .icon-folder-close-alt:before {content: "\f116";font-family: FontAwesome;}

tried with f204 and f205, getting empty squares..

Thank you

It's recommended not to use the codes. Instead, use the LESS variables (see icons.less)

But the toggle icons (f204 + f205) have been implemented in the latest version of FA (4.2.0), which has just been implemented in WCF 4.1

WCF 4.0 uses FA 3.2.1

Hm, WoltLab doesn't use the LESS variables either and as far as I know, @Alexander Ebert said sometimes in the forum that you should use the codes directly and not the variables because the latter change more often.

Quote from Black Rider

WoltLab doesn't use the LESS variables either

https://github.com/WoltLab/WCF…all/files/style/icon.less

I don't mean the icon LESS file, which is a port of the icon names. I mean in their own LESS content, e.g.:
https://github.com/WoltLab/WCF…es/style/layout.less#L118

I ll just have to wait for 4.1

a simple input with toggle icon did not work for me

[data-board-id="3"] .icon-folder-close-alt:before {content: "\f205";font-family: FontAwesome;}

Try out this Plugin: Burning Board: Forum-Icons

i did,but no toggle icons within the package,

but i will try to manually update it and replace required FA files

yes, you could upload the needed icons als Images

FA icons are not images,

I used FA generator, downloaded .png FA icons and added to CSS style.

i know, but as an workaround it is possible
