==Summary==
*Can now leave a proportion of trees cut in thinning in forest as dead wood
*New result variables for dead wood >= 20 cm diameter
*New management systems in RegWise: Checkerboard Management and Nature Conservation Management
*New result type: Disturbance Risk
*Simulation of initial soil carbon stock in litter
*Simulation of soil carbon in peat
*Improved calculation of breeding effect
*Expanded User Results definitions to include maximum diameter and age
*Several bug fixes in tactical simulation

==New Features==
===Leaving thinned trees as dead wood===
It is now possible to leave a certain proportion of trees cut in thinning “unharvested”, to become part of the forests dead wood pool. This to enable simulation of a nature conservation adapted treatment. In control table Treatment Model > Leave stems in forest after treatment, the percentage of thinned trees to be left as dead wood is given by the user (Default value: 0%).
===New result variables for dead wood with 20 cm diameter and coarser===
It is now possible to account the estimated volume of dead wood, standing and downed respectively, with a diameter of 20 cm and coarser, see Result Variables > Dead Wood. If the initial volume of dead wood is simulated, in control table Dead Wood > Initial dead wood, the proportions of dead wood with 20 cm diameter and coarser (of the total volume of dead wood) are based on Swedish NFI data (50% in Norra Norrland, 60% in the other regions of Sweden, and 70% in nature reserves).

====Project imported data set to new start date (Beta)====
Heureka now has a function (Beta version) for projecting the state of an imported data set, from the inventory date specified for each stand, to a desired start date for a new analysis. The program then creates a new area and the old data is not affected. In the projection, the program asks if you want to include treatments that have been carried out since the inventory.

====Conditional control tables - direct linking of control tables to stands====
"Conditional control tables" is a way to link specific control tables to stands, and takes precedence over the links created via forest domains and control categories. The feature is particularly useful if you have many different geographical regions in an analysis area, for example price regions, and can help keep the number of forest domains and control categories down to a minimum.

====New result variable for total dead wood volume====
To get total dead wood volume, you must sum volumes over decay classes manually, which prevents making graphs and tables that shows the total volume of dead wood. Therefore, a new result variable called "Volume Deadwood All Decay Classes to Include" has been added. You can select what decay classes that should be included in this variable in the Dead Wood control table. For example, you may prefer to exclude the classes with almost completely decayed wood. All decay classes are included by default.

====PlanWise: Let non-fertilization alternatives be generated automatically ====
A new setting in the Treatment Program Generator control table called "Also Generate Programs without Fertilization" simplifies things if you want create treatment programs both with and without fertilization. If the parameter is set to true, you do not need to add a separate control category to generate non-fertilized alternatives, they will be generated anyway.

====Explicit dates saved ====
In previous versions only the inventory year has been saved in the database when importing data, but now on the explicit date is kept (if available). The column name "InventoryYear" in the stand register is renamed to "Date" (although "InventoryYear" can still be used as column name).

====Multiple TPG-simulation can be included in the same optimization model ====
When solving an optimization problem, multiple TPG-simulation results can now be selected as input data. A condition is that no two TPG-simulations contains the same treatment unit, and an error message will be displayed of that criteria is violated.

 ===Adjustment of the growth in the first period in RegWise===
 In RegWise it is now possible to adjust the net growth in the first 5-year period with a factor, FPGA, to obtain a more realistic growth later used in specifying the harvest level of the first period. In earlier versions and when using the Harvest Level Factor (HLF) to specify the harvest levels in all periods of the planning horizon, the harvest level in the first period was often overestimated due to overestimation of the growth in the first period.

 ===Changed default settings===
 To enable more realistic simulations and obtain more realistic results several different default settings have been changed:
 ====Default settings in optimization====
 Rounding to integer solution is now set to "Off" by default.

 ===Ändring av mortalitet i hänynsytor===
-Utvecklingen på en hänsynsyta påverkas genom att mortaliteten ökar under 10 år efter slutavverkning av huvudbeståndet. Vi ändrade default-siffrorna från tidigare 12 % (första femårsperioden efter slutavverkning i föräldrabeståndet) och 6.8 % (andra perioden) till 9 % och 4.5 %, enligt en studie från 2015.[http://www.sciencedirect.com/science/article/pii/S0301479715001176]
+The mortality in nature conservation areas/retention patches are by default increased for two 5-year periods following the final felling of the parent treatment unit. Based on more recent findings (Roberge et al. 2015)[http://www.sciencedirect.com/science/article/pii/S0301479715001176], the default values of annual mortality rates are now set to 9% in the first and 4.5% in the second period. In earlier version the default values were 12% and 6.8% respectively.
