The user can now shift-click on a BC in the canvas to select that BC from the library for drawing
New pipe types (epoxy, HDPE) and pipe diameters added
Improved the way read-only models are visualized to the user
Zone volume can now be relative to the installed power. The zone volume dialog offers the alternatives to specify a volume, or to provide a volume-to-power ratio
PICV model improvements: minimal pressure default value is now 25kPa instead of in relation to the flow rate
Complete french translations for server resources
Removed restrictions on heat pump temperature
Pipe length lockable on floor plan drawings
Enable reverse-return and collectors tools in floor plan canvasses
Extend floor plan canvasses to allow all features we support on P&ID canvasses.

Bugfixes

Issue with floor plan drawing for cooling
Issue where cooling labels had strange CH label instead of just C for Cooling
Issue where the primary return temperature in heat exchangers was not computed correctly.
Issue where an Active Mixing error was not translated
Issue where CHP model has duplicate integral values for thermal power, removed one of them.
Issue where evaporator heatflow is not computed for the gas absorption heatpump and is displayed as 0.0 in integral values and plots. Evaporator heat flow has been removed for the GA/HP.
Issue where pump selection report didn't include Basic Circuit labels, and reported all evidence loops instead of just the one with the most resistance
Issue with attaching floor plan to canvas in the new version of Chrome
Issue where exporting to PDF is influenced by the type of canvas

Changes as of 7-jul-2017 

Features

On satellite unit and satellite heat exchanger, the DHW design flow can now be specified as either a "concurrent flow rate" provided by the user, or as a combination of different tapping point counts
Restyled pipe labels for CH + DHW combined flow rates
Reworked the way UA values can be supplied to satellite units and satellite heat exchangers. The software now accepts constant values, lookup tables, code fragments, and the 'classic' satellite unit parametrization
Ask a question feature was extended with a 'receiver' field
Added supply temperature to mixing circuit with primary bypass
Added primary power/flow propagation option on Satellite Heat Exchanger
Allow for undersized boilers to be installed up to a certain percentage.
Added activation signal to supply pump with external control and limited modulation to minimum rpm
Added shortcut key (Ctrl+H) to switch pipes between heating and cooling
Primary design temperature parameter on satellite unit Basic Circuit was removed. For propagation of the temperature regime over the DHW heat exchanger, the central heating supply temperature is used as primary supply temperature
Simulation model for satellite units modified to match the satellite heat exchanger simulation model
Simulation model for satellite heat exchanger and satellite unit validates tapping flow and warns when tapping flow exceeds design tapping flow

Bugfixes

Issue where Ctrl+Z reset the active canvas to the first canvas.
Issue where gas absorption heat pump, heat pump chiller and heat pump heating and cooling were not included in the energy report
Issue where SEPCOLL grouped circuits did not offer temperature override option
Issue where default authority for radiator valves was too large, adjusted to 0.1
Issue where liter/minute was abbreviated as l/m instead of l/min
Issue where gas absorpsion heat pump simulation yielded 'NaN' KWh values for primary fuel consumption
Issue where Flow Regulator didn't play well with zero flow rates...
