+## 2022-08-25
+- Add  `MAXCONN` environment variable to limit max connection among backends  (default to `0` - unlimited) [sauzher]
+- Add `STATS_REFRESH` environment variable to enable auto refresh. (default to `0` - no refresh) [sauzher]
+- Add optional weight parameter for remote backends `host:port:weight` (default to `1` - all same weight) [sauzher]

 ## Logging
 
 By default the logs from haproxy are present in the docker log, by using the rsyslog inside the container (UDP port 514). No access logs are present by default, but this can be changed by setting the log level.
