+[IMPORTANT]
+In scripts, with WeeChat ≥ 2.0, the callback arguments _status_, _gnutls_rc_
+and _sock_ are integers (with WeeChat ≤ 1.9, they were strings). +
+To be compatible with all versions, it is recommended to convert the argument
+to integer before using it, for example in Python: `int(sock)`.
