Hotfixes for MIKE 2021 (no service pack required)

MIKE View hotfix 03-05-2021
This hotfix corrects errors in the MIKE View Statistical Analysis tool.
MIKE+ hotfix 06-04-2021
This hotfix solves issues with location of distributed single sources and precipitation maps from 2D files, in 2D Overland simulations.
DHI License Manager hotfix 10-03-2021
This hotfix solves a “"no connect info" issue when using DHI Internet License on a Windows Server 2012 operating system.
LITPACK hotfix 01-02-2021
This hotfix corrects the generation of the wave direction axis in the littoral drift transport tables.
MIKE Zero hotfix 20-01-2021
This hotfix solves an issue with incorrect interpolation values in the Time Series Comparator.
MIKE+ hotfix 18-01-2021
This hotfix for the Water Distribution module corrects errors in water hammer simulations, respectively related to boundary conditions, pumps start up, and air-valves not correctly configured in the simulation.
MIKE+ hotfix 15-01-2021
This hotfix corrects various issues for SWMM models, especially related to import of data (from MIKE URBAN classic or inp files) and export of the simulation file. It also corrects a wrong logic in the editor preventing from editing the roughness value for force main conduits.
MIKE 21 hotfix 08-01-2021
This hotfix solves an issue in MIKE 21 SW related to progress visualization and the ability to stop a simulation in progress.
MIKE+ hotfix 05-01-2021
This hotfix corrects three issues in MIKE+: it crashed when picking up a node for the ‘From node’ and ‘To node’ fields with SWMM, 2D overland’s surface roughness was incorrectly set up in the simulation when using 2D infrastructure layers but without combining with a land cover layer, the ‘Catchment delineation’ tool was not displayed properly with Chinese Operating Systems.
MIKE HYDRO hotfix 27-11-2020
This hotfix corrects an error that prevented running small MIKE HYDRO Basin setups without a license for demonstration purposes
MIKE+ hotfix 27-11-2020

This hotfix corrects four issues in MIKE+: the inner diameter of pipes for Water Distribution was not visible, the ‘Zone mapping’ tool did not isolate zones in presence of pumps or open valves, connected nodes were sometimes lost for some SWMM conduits after importing scenarios from MIKE URBAN classic, and MIKE+ randomly crashed when configuring 2D overland simulations to run on GPUs.
