-* Notifications are now transient by default. That is, when a notification

 * When checking for a buffer-name match, consider `>channel` and `#channel` to
   be equal. The reason is that the
   [wee_slack](https://github.com/rawdigits/wee-slack) plugin replaces `#` with
   `>` to indicate that someone in the buffer is typing. This fixes the behavior

 * Made notifications for ordinary messages look like highlight notifications
   when the buffer is in `notify_on_all_messages_in_buffers`. Previously, such
   notifications looked like private-message notifications, which was
   misleading.
 * Do not show notifications for messages without a nick. A nick is required to
-  form a correct notification source/message.
+  form a correct notification source and message.
 * Fixed displaying of notifications without a source. Previously, `notify-send`
   failed with the following error message: `No summary specified.`
 * Fixed shortening of messages containing non-ASCII characters. Previously, it
