I noticed silent change in WordPress.com. Probably I just missed their announcement, but I found out that some of my old posts don’t have correct format for displaying source code.
So, I tried to figure out what happen.
Previously these were allowed to display C++ code.
[ sourcecode language="c++" ].... [ sourcecode ]
[ sourcecode language="cpp" ].... [/sourcecode ]
However, now the first form is not allowed.
So, any post with tags like the first one will be displayed ugly.
What a change!
