Thread:Project:Support desk/wgArticle

Hello,

I wrote an extension which worked in earlier versions of Mediawiki, but doesn't work in 1.23. It appears that the global variable $wgArticle is no longer defined. Is it true? Is there another way to obtain this variable?

I am also curious about other changes that I need to be aware of. Is there a guide explaining how to migrate extensions to the newer version? Tnanks!
