I found out about a new Minecraft update by watching Major Nelson's "this week on xbox" and used the above link to check out the changelog - and there it is!

Finally, as of *December 8th 2015*, the update [TU-31](https://minecraft.wiki/w/Console_Edition_version_history#xbox-TU31), which equates to 1.8, listed the following change:

> Villagers have additional professions and trades, **will now harvest crops if they are farmers**, will only breed when willing and will turn into witches when struck by lightning.

About bloody time.
