'''Geo'''
* Dutch CBS data is loaded into the Neighborhood, providing information about the population in the neigborhood (e.g. age, sex, ethnic diversity, etc).
* Dutch Agriculture is now loaded into the map. The official "gewascode" is also stored as an attribute.
* Waterhomes are loaded.
* More sources are optional/selectable via "advanced options" in the Area selection panel.
* Option to only update values of existing Items via GeoJSON files.

'''Performance'''
* 3D buildings are rendered faster. 
* Loading time of the maps has been improved.
* Popup performance has also improved (for maps with 100+ popups).
* Template loading time is improved.
* Map saving time is 3 times faster.
* Closing of a running Wizard Session has improved.
* Improved webserver (network) speed, e.g. updates are directly streamed from memory to the client.
* Performance has also improved (TQL statements are processed faster).
* Option to lower the accuracy for very large grid overlays, thus improving calculation speed.
*Faster calculation of the grid overlays by changes to the GPU architecture. 
*Better caching of Geotiffs for ground water levels for faster refreshing of an overlay


'''Indicators'''
* All indicators are Excel based now. This includes the personal finance and housing indicator who are linked via a new TQL statement to a specific Stakeholder. You can also make all other indicators personal (linked to a stakeholder). 
* The QUALITATIVE indicator was hardly used and it functionality can be replaced with TQL/Excel. Thus we have deprecated this Indicator.
* The API Indicator, like the QUALITATIVE indicator, was rarely used and has been deprecated.
* Indicators that have an update TQL call will be executed before Indicators that do not. So you can for example update your cost in Indicator 1 after which Indicator 2 (e.g. finance) can read in the new  value. 
* All Indicator- and popup panels are now loaded as web pages, giving you more flexibility for styling.
* Excels can now also use the latest Excel CONCATENATE (CONCAT) function. 
* Improved indicator update time by factor 10 for TQL statements that use grid data.
* Improved indicator calculation for large amounts of Excelsheets (e.g. 5000+)
* Global values can now be updated from one excel (UPDATE_GLOBAL) into another excel (SELECT_GLOBAL).


'''TQL'''
* Included a new TQL statement XA that allows users to select Items in de TQL query based on an attribute. ( e.g. SELECT_ID_WHERE_AREA_IS_X would show all Areas, using SELECT_ID_WHERE_AREA_IS_XA_PEIL would only show the areas with an Attribute PEIL (where value !=0).)
* New statements to check your budget (REVENUE and EXPENSES).
* New statement STATE that can be used by your Excel to see if the session was started. 0= editor mode, 1= first calculation round (use to init values at start of session) 2= remainder of session. See housing indicator for an example.
* Option to load specific Items with the X-query: use XA to select only Items with a specific attribute and add SORT to sort them on a specific attribute.
* New clauses available: ATTRIBUTE_MAX, ATTRIBUTE_MIN, ATTRIBUTE_MULT, to select Items in a specific attribute range. 
* To prevent roundoff errors, the Grid calculation is done on the orginal calculated values now.
* Option to set and remove attributes for all Areas at once. And option to create border areas between them.
* Added the new GRIDVOLUME Clause type that calculates e.g. the water volume in an area.
*The GRIDTYPE clause is deprecated. Use instead the GRID clause, in combination with the ID of the overlay (old queries using the gridtype clause will still work)


'''Overlays'''
* Correctly show overlay data in all zoomlevels.
* The Average Overlay can now also load attributes from Areas and Neighborhoods.
* Smaller grid cells, down to 0.5mx0.5m per tile.
* Overlays: livability, avg and heatstress now auto-calculate their range, impoving visual quality and accuracy.
* GeoTIFF export is done on the orginal values, no round-off values anymore.
* Server now uses the Tygron Cluster to delegate off GPU calculation tasks, this improves the calculation capacity to 20 GPU's in parrallel (3584 * 20 = 77.080 cores).
* The Distance Overlay (distance to object) has been changed such that a larger radius - with a maximum of 2km - is now possible.
* It is now possible to make multiple Distance Overlays (by 'filling' it with any attribute). This also goes for the Average and Sight overlay. 
* The visualization of the Distance Overlay has been improved.  
* Subsidence overlay is extended now including: settlement and oxidation per year indexation and also climate factors.
* GeoTIFF overlay, this overlay can display your own grid data.
* The AVG overlay can now also display included attributes from neighborhoods, areas, terrains and buildings.
* The Attribute overlay allows user to customize a color via Excel, therfore providing more flexibility in visualization.
* Loading in new maps with the Wizardhttp://support.tygron.com/wiki/Special:WhatLinksHere/Version_2017.3.0 is faster for terrains, water and land-use. This is especially useful for larger maps.
* A new protocol for communication between Tygron Servers improves calculation time for large overlays.
* A Larger stack size improves calculation time for large Excelsheets.
* Improved uploading of the GeoTiff Overlay (identical to Excelsheet handling).
* New Subsidence configuration Wizard.
* Both Rain and Subsidence are connected to the Geo Data Wizard.
* Avg Overlay can now also only calculate averages for single cells. Useful for showing rasterization of data used in other overlays.
* Avg Overlay can now also show values from a specific layer (e.g. buildings or areas)


'''Rainfall overlay:'''
*Multiple result types can now be calculated at once and visualized in the overlays bar at the right as a group, where you have a parent result type and child result types. This is also applicable to the Subsidence overlay(s). 
*Implementation of the discharge calculation (stuwformule), which ensures a more refined calculation of the water flow between water level areas. Attributes: WEIR_WIDTH, WEIR_COEFFICIENT (default 1.1, different types of weirs have different flow coefficients), WEIR_N (the default value 3/2 is for a horizontal weir, change accordingly for your type of weir)
*Implementation of two new hydrological constructions (pump and culvert) next to the already existing weirs and sewer overflows to define different relations between (water level) areas
*The new result type ‘ Building impact’, which shows all the constructions which will be flooded (defined by the IMPACT_FLOOD_THRESHOLD_M attribute) with the set rain event type. The result type is also a visualization of the new attribute ‘CRITICAL_INFRASCTRUCTURE’ in the function values table, in where a categorization in critical buildings is made. The values that can be entered in the function values table are: not critical = 0 (for example sheds or a park), important = 1 (most buildings), critical = 2 (such as a hospital or a school). 
*The rain event type can either be set to an equal distribution of rain, or an adjustable distribution of rain over time for modeling for example when it is raining harder at the start of a rain fall
*More insight in when the Engine is calculating a result
*The speed for water flowing over the sewer overflow buildings to surface area water is adjustable (attribute: SPEED in m3/sec)
*Fixed various bugs, wrong user input and border cases for the Rain Model.
*Added Courant number, which is a measure that indicates if a grid model is calculated with enough cycles (time steps). The Courant number can be found in the Rain Overlay debug info, shown in the Editor.
*Placed a limit on the maximum velocity water can travel.
*Added a Maximum Speed overlay, which records the maximum velocity water has moved in a cell during the entire Rain simulation. 
*Improved calculation time of min-max gridvalue TQL queries for Rain Overlays.

*Added Show in map button.
*Added new result type overlays.
*Improved input fields. F.e. Pump Speed may not be negative.
* Include negative outlets in the Water Balance sheet.
* Rainfall overlay makes use of surface runoff, underground storage, weirs and sewers, to calculate water stress.
* Rainfall overlay includes  now: evaporation, sewer overflows, a watersystem visualization and default popups.
* The water balance includes the water levels over time per water area now.
