+## 0.4.2 - 16/06/2017
+Fix another problem on generate installation identifier to sendo for statistic
+
+## 0.4.1 - 14/06/2017
+Fix problem on send identifier installation for statistic
+
+## 0.4.0 - 14/06/2017
+Add credentials support to socket server (define TCPSERVER_USER and TCPSERVER_PWD in your config file)
+Add management lock/unlock for prevent concurrente call to open/close solenoid
+Added the ability to enter an open / close schedule in disabled mode
+Add send statistic information to remote server
+During the initialization function, information on the last rain is no longer removed
+
+## 0.3.1 - 13/05/2017
+Add experimental support for monostable solenoid valve:
+- define in your config file the variable EV_MONOSTABLE and assign value 1
+- if the solenoid valves close instead of opening and vice versa, reverse the values of the RELE_GPIO_CLOSE and RELE_GPIO_OPEN variables in your configuration file
+
+## 0.3.0 - 07/05/2017
+Add command "open_in" for scheduling on the fly the opens/close a solenoid
+Add command "del_cron_open_in" for delete scheduling the fly the opens/close a solenoid
+Add api in socket server for command open_in and delete_cron_open_in
+Fix minor bug on command "open"
+Changed the path of some temporary files to prevent sd card faults
+
 ## 0.2.2 - 25/04/2017
 Fix bug: if it's reining, the solenoid valves were also closed even if they were pushed open in "force" mode
