When items are tagged with "obsolete" it reads as follows:

"This content is compatible with older edition(s) of the game it was made for, and not guaranteed to work with the current or development versions."

this is actually bad grammar it should read like on of the following:

"This content was made for older edition(s) of the game, and not guaranteed to work with the current or development versions."

"This content is compatible with older edition(s) of the game, and not guaranteed to work with the current or development versions."

"This content is not guaranteed to work, because it was made for older edition(s) of the game."

Just wanted to point that out
