Let's Encrypt 的官方 Client 決定改名，不過目前還沒有公佈新的名字：「New Name, New Home for the Let's Encrypt Client」。
主要是兩個原因，第一個是避免商標問題：
[...] we want the client to be distributable and customisable without having to create a complex process for deciding whether customized variants are appropriate for use with Let’s Encrypt trademarks.
另外一個是希望之後有其他的 CA 也可以用：
Another reason is that we want it to be clear that the client can work with any ACME-enabled CA in the future, not just Let’s Encrypt.
