I'd like to use the bottomrule option for the tcolorbox environment, as shown in the tcolorbox manual on page 12.

Unfortunately, the option does not seem to work, and the following code creates a standard tcolorbox instead of a bottomruled tcolorbox.


This should be a bottomruled \textbf{tcolorbox}.

The option should set the bottom boundary height to 3mm instead of the standard value (0.5mm), but it does not seem to do nothing. Similar options like toprule, rightrule and leftrule do not work, while boxrule (which sets the height of all boundaries) works.

Any idea what the problem may be?

After updating to the last version of tcolorbox the output is as expected

Can you provide an image of what you are seeing. I am no expert in this, but it appears to be working for me with TeXLive 2012. – Peter Grill Mar 17 '13 at 21:04
I don't see a bottomrule key in tcolorbox (as a matter of fact, I don't see toprule, rightrule or leftrule either); according to the package documentation, there's a boxrule key to change the width of the whole frame. – Gonzalo Medina Mar 17 '13 at 21:06
I'm referring to this manual: mirror.unl.edu/ctan/macros/latex/contrib/tcolorbox/… pag. 12 – domenico Mar 17 '13 at 21:08
Then, maybe you are using and outdated version of the package (as I am doing myself); you could update the package (I will do this right now). – Gonzalo Medina Mar 17 '13 at 21:09
yup, you're right, mine was outdated too. I was too confident in archlinux devs :D Thanks – domenico Mar 17 '13 at 21:25
