-    - ~mu4e~ queries are much snappier now. ~mu4e~ benefits from the mentioned
-      speed-ups in querying, and adds some of its own - e.g., for showing 500

+    - ~mu4e~ queries are much snappier now, due to the mentioned speed-ups in
+      querying; ~mu4e~ also adds a new optimization =mu4e-mu-allow-temp-file=
+      (turned off by default), which speed up things further; e.g., for showing
+      500 messages (debug build), we went from 642ms to 247ms, given an

     - after retrieving mail (~mu4e-update-mail-and-index~), save the output of the
