Upgrade instructions

Move or delete all files from the logs directory. The reason is that starting from this version, the logs are in different format, and old logs cause failures when trying to show them in the “Logs” screen.

application.yml

Be sure to update application.yml, it often contains new necessary settings. Probably you need to do accuracy merge old application.yml and new one.

Also, with ver.36 we have logback.xml moved to conf/logback.xml , near by the application.yml. It will allow customer to tune logging policy. So, please make sure that logback.xml is also properly updated.
