The changes in this beta will be available in the 4.11 production release, due out at the end of December 2019.

The biggest feature in this release is Combine catchments. It also includes:

Climate Data import tool improvements, including the ability to extend the duration of data
Zoom all the time with the scroll wheel for Catchment Scenarios
A fix for projects being corrupted by windows that affected a small number of users
Modelled variables being more stable when moving links.

Combine Subcatchments

You can now combine sub-catchments in a geographic scenario:

From selected catchments:

The first catchment selected is deemed to be the Primary Catchment.

At the moment you need to have a single outlet for all of the sub-catchments you are combining. We will relax this restriction in future versions.

At Selected Node Boundaries:

You can select a single node and combine all of the catchments upstream of it.

Blackwater plugin

Initial conditions can now be specified as varying according to elevation

Plugins

ScenarioRunFinalise now happens on all plugins. If there was an exception in one plugin, it previously wouldn't run ScenarioRunFinalise for the remaining plugins when there were multiple plugins.

Plugin Developers

We are planning on moving to C# 7, Visual Studio 2019 and .NET 4.8.0 soon, so you will need to make sure you have updated Visual Studio to continue developing plugins in the beta versions.
