== Q&A ==
 +
Q: I changed a string for a category via pull request (and it got accepted and merged). Will the new string appear on all the products once a new version is deployed and released?
 +
 
 +
A: It depends. The canonical categories (e.g. en:cakes) that are associated to each product won't be updated right away, only when products are processed again. The strings displayed for it (e.g. if you added a translation) will be shown right away.
