We have been working on a number of issues, including:

changes to stop Modelled Variables breaking when the Function they point at is moved
improving the handling of distribution system loss with travel time
improvements to Weirs, including mass balance for constituents with lumped routing
fixing the non-debit user interface
resolving several charting issues.

We have also made progress with the issue of different results for some models on different hardware. We found that the .net System libraries of Math.Pow() and Math.Exp() produce different results on different machines. We are implementing custom versions that produce consistent results on different hardware. This will be available in 4.8.3beta. This fix solves the problem for one of the models, however, one model still has inconsistent results on different hardware. We are continuing this line of investigation to attempt to resolve the problem for this remaining model.

Plugin Developers

We are planning on moving to C# 7, Visual Studio 2019 and .net 4.7.2 soon, so you will need to make sure you have updated Visual Studio to continue developing plugins in future beta versions.
