Switch King client version 3.1 released

Version 3.1.0 of the client is now released and contains several news, e.g.:

• Linear value mapping makes it easy to for instance add an offset to collected data source values or to multiply a value with a constant. This function can also be used to calibrate a data source against a reference (e.g. for temperature transmitters).
• Data source values can now be exported to file for further analysis.
• Lists with rules, linked schedules, etc, are now sorted showing selected items first in the list. This makes it easier to administrate the system as the number of objects grows.

See Change log for client for more information about this release.
