• The value mapping of a data logger set up by mapping values can be changed through "Edit metrics".
• The mapping of an irradiation sensor on a data logger now records whether it measures horizontal or module-level.
• Strings on several selected inverters can now be edited in one step on a plant's components page.
• A plant's pages no longer show the on-site agent as not responding right after a configuration change restarts it.
• A plant's solar analysis page no longer shows a clear-day count larger than the days its inverters have been reporting.
