 ## Features

- Very (very !!) fast broker I saw it re-sent 1000 topics per second for two
+- Very fast broker I saw it re-sent 1000 topics per second for two
  clients that had subscribed (payload ~15 bytes ESP8266). No topic lost.
  The max I've seen was 2k msg/s (1 client 1 subscription)
 - Act as as a mqtt broker and/or a mqtt client
 - Mqtt 3.1.1 / Qos 0 supported
+- Wildcards supported (+ # $ and * (even if not part of the spec...))
 - Standalone (can work without WiFi) (degraded/local mode)
 - Brokers can connect to another broker and becomes then a
  proxy for clients that are connected to it.
 - zeroconf, this is a strange but very powerful mode where
  all brokers tries to connect together on the same local network.
+- small memory footprint (very efficient topic storage)
+- long messages are supported (>127 bytes)
+- TinyMQTT is largely unit tested, so once a bug is fixed, it is fixed forever
+
+## Limitations
+
+- Max of 255 different topics can be stored (change index_t type to allow more)
+- No Qos because messages are not queued but immediately sent to clients

-  Version 6 library changes
-    Copyright (c) 2019 Gazoodle. All rights reserved.
-
-  1.  _BASED moved to template to remove type conversion to long and
-      sign changes which break int8_t and int16_t negative numbers. 
-      The print implementation still upscales to long for it's internal
-      print routine.
-
-  2.  _PAD added to allow padding & filling of characters to the stream
-
-  3.  _WIDTH & _WIDTHZ added to allow width printing with space padding
-      and zero padding for numerics
-
-  4.  Simple _FMT mechanism ala printf, but without the typeunsafetyness 
-      and no internal buffers for replaceable stream printing
