Hi, I just installed the latest version of log5 from github and found a copule of typos: In handle-message '(,@args) should be (list ,@args). In %handle-message (declare (dynamic-extent (function find-or-create-output handle-message-for-sender))) should be (declare (dynamic-extent (function find-or-create-output) (function handle-message-for-sender))) Thanks, Ilya
