v0.7

• Notifications are transient by default. That is, when a notification expires
  or is dismissed, it is removed from the notification bar. To disable this
  behavior, set the plugins.var.python.notify_send.transient configuration
  option to off.
• When checking for a buffer-name match, consider >channel and #channel to
  be equal. The reason is that the
  wee_slack plugin replaces # with
  > to indicate that someone in the buffer is typing. This fixes the behavior
  of several configuration options (e.g. notify_on_all_messages_in_buffers)
  when weechat_notify_send is
  used together with wee_slack.
• Do not show notifications for some messages that were ignored in previous
  versions of the plugin. More specifically, do not show notifications for
  messages tagged with irc_part, irc_status, irc_nick_back, irc_401,
  and irc_402.
• 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 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
  might have happen that a message was split inside of a multibyte character.
  This created an invalid message and caused notify-send to fail.
