The description of this text (in English "center") says "Description of aligning text to center, used in describing change" which is not enough to understand the exact usage. How is it specifically used in describing change? In what context? And why is it written with an initial lowercase letter ("center")? It's important to know this in order to be able to translate it correctly.
Thank you everyone for your kind and helpful comments! 🙂 I understand the usage now, and I believe the documentation in translatewiki is now sufficient for others to be able to understand it too.
